Authors:   IAGBT, Yuni Rosdiana Yuni Rosdiana , Khomsiyah Khomsiyah , Harti Budi Yanti Harti Budi Yanti
Published: February 2024

Purpose - A society that cares about environmentally friendly products demands companies have a green competitive advantage through the application of the principles of Reuse, Reduce, and Recycle. The purpose of this research is to examine and analyze the influence of green organizational culture (GOC) on green innovation performance (GIP) and green competitive advantage (GCA).
Design/Methodology/Approach - The study collected data from 314 manufacturing companies that are members of Proper (Environmental Performance Rating Program) on Java Island. Data collection was conducted through online and offline surveys using questionnaires that measured each research variable. Structural equation modelling with SEM PLS software were applied to analyze the data.
Findings - The findings of this paper indicate that green organizational culture has a positive influence on green innovation performance. GOC also positively influences GCA, and GIP fully mediates the relationship between GOC and GCA.
Research Implications - This research contributes to existing literature on GOC, GIP, and GCA, taking into account environmental issues, which have been empirically understudied, especially in manufacturing companies that are members of Proper. Furthermore, this research also explores green innovation performance as a mediator, which has been relatively unexplored in previous studies. However, this research has several limitations, including the dominance of blue-rated Proper participant companies in the sample, as most questionnaires were distributed during the blue certificate awarding moments. Additionally, the sample size per province was uneven, with the majority of participant companies located in the province of West Java.

Published: February 2024

Purpose - This study examines the pivotal role of local expert reviewers in the financial success of imported foreign films (Hollywood movies) within the Chinese market. It integrates signaling theory and gatekeeping scholarship to examine how these intermediaries reduce mainstream uncertainty. We hypothesize local expert reviewers to better grasp spaces for resonance between imported films and local preferences compared to foreign critics. Moreover, we examine the moderating roles of films attributes such as production scale, prestigious awards, and local adaptation strategies.
Design/Methodology/Approach - We test hypothesized relationships and contingencies via OLS regressions on box office performance spanning 500 top-grossing Hollywood studio imports in China from 2000 2017 with data from multiple sources.
Findings - The OLS regressions reveal that local expert reviewers significantly influence cross-border film success, with the impact moderated by production budgets and awards, but potentially diminished by cultural adaptation.
Research Implications - Our study unpacks market drivers and product-level contingencies around imported creative products amidst mainstream uncertainty. The findings contribute to international business literature and cultural business by showcasing the nuanced impact of local cultural intermediaries on the financial performance of foreign cultural products. This research underscores the importance of local expert opinions in navigating the complex landscape of global content distribution and consumption, offering valuable insights for content creators and marketers aiming to optimize the global reach of products.

Published: February 2024

Introdução: O segmento protestante da religião cristã interpreta os textos bíblicos de várias formas no que diz respeito ao pecado e à sexualidade e corpo, ora a condenando, ora tratando-a como inerente ao ser humano. No Brasil, o protestantismo teve como influência o movimento puritano, que considera a sexualidade como perigosa e que deve ser evitada, gerando uma cultura de repressão que gera obstáculos no conhecimento sobre o próprio corpo pelas mulheres e em seu autocuidado. Objetivos: Investigar o autoconhecimento de mulheres evangélicas quanto ao próprio corpo e identificar o impacto da cultura protestante nesse autoconhecimento. Método: Pesquisa quali-quantitativa, realizada por meio de questionário estruturado sobre a anatomia do sistema reprodutor feminino e realização de dois grupos focais, compostos por: (1) mulheres solteiras e sem vida sexual ativa e (2) mulheres casadas com vida sexual ativa. Os dados foram analisados utilizando-se estatística descritiva e análise de discurso de Bardin. A presente pesquisa foi autorizada pelo Comitê de Ética em Pesquisa da Unicamp, CAAE 58364822.9.0000.5404/2022. Resultados: O questionário possibilitou identificar as principais lacunas de conhecimento quanto às estruturas anatômicas e os grupos focais permitiram identificar seis principais temas de discussão: (1) Sexualidade e autoconhecimento; (2) Experiências com a atuação dos profissionais de saúde; (3) Papel da Igreja; (4) Papel da família e da escola; (5) Conhecimento científico versus conhecimento tradicional; (6) Mudanças no processo de autoconhecimento entre as diferentes gerações. Conclusão: O avanço da discussão sobre corpo e sexualidade tem tomado forma com o passar dos anos no ambiente evangélico, evidenciado nos ambientes da igreja, da escola e da família, porém as mulheres evangélicas ainda encontram obstáculos nos serviços de saúde. Dessa forma, a Igreja tem impacto tanto positivo quanto negativo, podendo apresentar-se como um espaço de opressão, mas possuindo potencial de configurar-se como espaço de promoção de autocuidado e autoconhecimento.

Published: February 2024

Introduction: Despite the effective global mass vaccination programs, which included booster shots, the emergence of new SARS-CoV-2 strains threatens to undo the enormous success achieved thus far in stopping its spread. This study aimed to assess the demographics of COVID-19 patients from February to May 2021.
Methods: Data were collected using secondary data from the medical records of Klungkung Regional General Hospital, Klungkung, at the time range according to the study period. Statistical Package for the Social Sciences (SPSS) version 25.0 for Windows and Microsoft Excel 2016 were used for the statistical analysis. All quantitative data, such as age, length of stay, and neutrophil-to-lymphocyte ratio (NLR), were estimated using central location measures (mean range). Proportions were used to describe qualitative or category variables.
Results: The demographic description of COVID-19 patients at Klungkung Regional General Hospital, Klungkung, found an average age of 51.94 years old. More patients were found to be male (55.4%) and did not have comorbidities (55.3%). Fourteen patients (14.4%) were gravid, and 37 patients (17.8%) were treated in the Intensive Care Unit (ICU). A total of 61 patients (29.3%) had desaturase with an NLR (mean) of 6.97 (51% increase). The average length of stay was 10.16 days, with the result of 24 patients dying (11.5%).
Conclusion: Patients with COVID-19 were found to have milder symptoms with less use of the ICU, not all of them experienced decreased saturation, and the case fatality rate was 11.5%.

Published: February 2024

Introduction: Shortness of breath is the most distressing long COVID-19 symptom associated with the decline of small airway function, as shown by a decrease in forced expiratory flow (FEF) 25-75% value in the spirometry test. This study aimed to compare FEF 25-75% values as a predictor of small airway disease between mild-moderate and severe-critical long COVID-19 patients.
Methods: This study used a prospective cohort design that included 24 post-hospitalized COVID-19 patients who came to the long COVID-19 clinic at Universitas Gadjah Mada Academic Hospital (UGM AH), Yogyakarta. The subjects were divided into mild-moderate and severe-critical groups based on the World Health Organization (WHO) classification. The subjects were tested for spirometry three months after the onset of COVID-19 symptoms. The comparison of both severity groups used the percent prediction of FEF 25-75% spirometry results. The value was interpreted as abnormal if the predicted FEF 25-75% value was below 65%.
Results: There were three (25%) and two (16.67%) subjects with FEF 25-75% predicted below normal values in the mild-moderate and severe-critical groups consecutively, which showed a decline in small airway function. This study showed no statistically significant differences (p-value = 0.882) between the means of FEF 25-75% predicted values of the two groups.
Conclusion: A small proportion of post-COVID-19 syndrome patients had small airway disease, and there were no statistical differences in small airway function between the groups.

Introduction: COVID-19 disease has become a comprehensive world issue and has been declared a significant threat to global health. Interleukin-6 (IL-6) is an important inflammatory marker and one of the triggers of the cytokine storm in COVID-19, where increased levels can be an independent predictor of COVID-19 mortality. This study aimed to observe the effect of upper arm and breathing exercises on IL-6 levels in severe COVID-19 patients.
Methods: The study design was quasi-experimental, with blood tests conducted before and after the examination. A total of 20 patients with confirmed COVID-19 were involved, divided into intervention and control groups.
Results: Blood tests to determine baseline IL-6 levels were performed in all patients. Patients from the intervention group were given upper arm and breathing exercises for ten days, twice a day, via video tutorials on mobile phones, while patients from the control group did not receive any exercises. Patients from the intervention group obtained mean pre- and post-exercise IL-6 levels of 42.38 ± 48.48 and 16.78 ± 18.29, respectively (p = 0.005).
Conclusion: Upper arm and breathing exercises showed significant changes in IL-6 levels in severe COVID-19 patients.

Published: February 2024

Introduction: Community-acquired pneumonia (CAP) can deteriorate into respiratory failure requiring immediate ventilatory intervention. This study compared the performance of the PaO2/FiO2 (P/F) ratio, the ratio of oxygen saturation (ROX) index, and the heart rate, acidosis, consciousness, oxygenation, and respiratory rate (HACOR) score in predicting non-invasive ventilation (NIV) failure and length of hospital stay in patients diagnosed with CAP.
Methods: This study was conducted at Universitas Sebelas Maret Hospital, Surakarta, from March to September 2023. All patients diagnosed with CAP who were eligible for NIV were recruited. Each patient’s age, sex, comorbidities, vital signs, pneumonia severity index (PSI), blood urea, bilirubin, hematocrit, blood sodium, P/F ratio, ROX index, and HACOR score were measured within the first 24 hours of NIV. Subsequently, the correlations between these variables and NIV failure (intubation or mortality) and length of hospital stay were assessed.
Results: The P/F ratio, ROX index, and HACOR score were not correlated with intubation or length of stay. The P/F ratio was correlated with mortality (p = 0.040), whereas the other scores were not. Higher body temperature was correlated with intubation (p = 0.032). PSI was correlated with both mortality (p = 0.033) and length of hospital stay (p = 0.009).
Conclusion: The P/F ratio is superior to the ROX index and HACOR score in predicting mortality in patients with pneumonia-related respiratory failure treated with NIV. Since it is simple and accessible, measuring the P/F ratio within the first 24 hours of NIV is recommended to identify a patient’s risk of NIV failure and apply appropriate monitoring.

Published: February 2024

Introduction: People with tuberculosis (TB) have an increased risk of pulmonary cancer. They are also disproportionately affected by risk factors like immune suppression, smoking, and alcohol misuse. A lung tumor is reported to have occurred after an episode of TB, but we reported a patient with a lung tumor with co-infection TB and lung abscess at the same time.
Case: A 73-year-old man was hospitalized at Arifin Achmad General Hospital, Pekanbaru, with a 3-day history of bloody cough 2-3 times a day, 1-2 tablespoons estimated by the patient for blood from the cough. The patient had a cough with white phlegm in the last 4 months before the bloody cough. The patient also had a fever, night sweats, a limp body, decreased appetite for 6 months, and decreased body weight by 15 kg in the last year. Heterogenic consolidation on the superior lobe of the lung with prominence compression and irregular boundaries in the apex was found. We found an air bronchogram and multiple cavities with air-fluid levels inside the lesion. We also found a satellite nodule in the inferior lung and a mass connected with the chest wall. GeneXpert showed low detection for Mycobacterium tuberculosis. The patient was diagnosed with a left lung abscess, pulmonary TB, left lung tumor T4N2M1a, unspecified type of tumor stage IVA PS2, and osteoporosis.
Conclusion: Lung tumors could also be diagnosed with co-infection TB. Proper diagnosis to make sure cancer and TB are co-infected is necessary. Therefore, it will not be just a single disease that is treated.
Cycloserine- and Fluoroquinolone-Induced Seizure in Multidrug-Resistance Tuberculosis (MDR-TB) Patient: A Case Report
Authors: Yanifitri Dewi Behtri , Arliny Yunita , Utami Wilia Aprilisa , Winardi Wira
Published: February 2024

Introduction: Multidrug-resistant tuberculosis (MDR-TB) is a type of tuberculosis (TB) that is resistant to at least two of the most effective first-line anti-TB drugs, isoniazid (H) and rifampicin (R). Cycloserine (Cs) and levofloxacin (Lfx) are second-line anti-TB drugs used in MDR-TB therapy. Even though they are considered to have high effectiveness, both drugs have the potential to cause side effects. One important side effect is neurotoxicity. Seizures have been reported as a common complication of some drugs.
Case: A 39-year-old man was diagnosed with MDR-TB and was treated with individual regimens consisting of Lfx, bedaquiline (Bdq), linezolid (Lzd), clofazimine (Cfz), and Cs. After consuming anti-TB drugs for 27 days, the patient had seizures several times. The patient experienced full-body seizures and loss of consciousness during the seizures. Cs and Lfx were discontinued and replaced by other regimens. Serial electroencephalogram (EEG) showed normal results. After Cs and Lfx were discontinued, the patient never had another seizure.
Conclusion: Management of MDR-TB is sometimes complicated because of severe drug side effects. Patients taking Cs and fluoroquinolones (FQs) should be advised to report any sign of seizure or changes in mental status to their healthcare provider.

Published: February 2024

Biomedical science, which initially required only conventional research in the laboratory, currently involves information technology and has created bioinformatics in its development. Bioinformatics, a branch of biology, quantitatively analyzes information within biological macromolecules using software. Contemporary applications of bioinformatics have advanced biotechnological, medical, and pharmaceutical practices. Among the established applications of bioinformatics is diagnosing lung diseases using the genome-wide association study (GWAS) technique. Owing to sequencing technology and rapid computational methods, this technique is applied to analyze the link between genes with essential traits in the population, thus mapping the target genes to diagnose and treat diseases. The lung diseases diagnosed using GWAS include the responsible locus in asthma, chronic obstructive pulmonary disease (COPD), and lung cancer. Moreover, it can identify the treatment for COPD and suggest a new locus in lung cancer. Advancing the current gene-mapping technology demands genotype and phenotype data to study disease-linked genomes. Currently, bioinformatics is barely known and receives little attention in Indonesia. However, it can grow rapidly through open-source basis data and cross-disciplinary collaboration.

Improving Casing Running Efficiency through a Comprehensive Wellbore Quality Scorecard: A Data-Driven Approach
Authors: Cockburn C. B. , Huseynzade N. , Rasul-zada A.
Published: February 2024

This paper presents the successful development and implementation of a wellbore quality scorecard which is used to evaluate wellbore quality using deterministic and probabilistic methods. This evaluation is based on analysing the real time data during the final trip out of hole with the drilling BHA.

The Wellbore Quality Scorecard is being used systematically across a large multi-asset drilling project where there was a history of problematic hole sections. Casing and liner running operations frequently encountered difficulties, and it was recognised that a system for evaluating the hole condition would help to improve operational decision making. The result of the evaluation is used to provide a better understanding of the condition of the wellbore that was drilled before committing to run casing or liner. Understanding the wellbore condition helps the team to decide, for example, whether to run a wiper trip to condition the wellbore or to save time and go ahead with casing or liner run.

The evaluation process is a collaboration between the remote collaboration centre, the rigsite team and the office-based operations team. A database is generated which records historical wellbore condition vs liner and casing running information which holds very useful technical insights about how each wellbore parameter quantitatively affects the wellbore quality.

The paper will describe how this process has now been applied to over 50 hole sections, and how it has improved decision making and the liner and casing running success rate.

A machine learning model has been developed which predicts the likelihood of successfully running the casing or liner to the target depth. This information is used to compliment the Wellbore Quality Score for informing operational decisions.
Implications of Setting a Centralized Production Liner on Bottom: A Numerical Approach
Authors: Esteva M.
Published: February 2024

Occasionally, operations require setting a production liner on bottom. This could be unintentional, e.g. when the liner hanger slips fail to operate, or intentionally, e.g. when the liner is purposely run without a hanger to guarantee sufficient bypass area. A consequence of setting the liner on bottom is that the buckling force will be compressive, and assessment of the buckling severity is required to avoid high buckling induced dogleg severity (DLS). After the liner is cemented, the induced DLS is made permanent. Thus, this change in well path trajectory could jeopardize the runnability and installation of completion equipment.

In this study, the buckling induced DLS is estimated using a finite element based stiff-string model. The model takes in consideration the additional compressive loads of setting the liner top packer. It also accounts for liner centralization. It was found that this model overcomes the limitation of the theoretical models implemented in widely used commercial casing design software as it captures the physics of the buckled casing in between centralizers with more accuracy.
Blind Trust: Challenges in Data Sharing for Oil and Gas Well Construction
Authors: Willerth M. , Gibson D. , Fortney R. , Piskin A.
Published: February 2024

The drilling and completion of oil and gas wells is a collaborative business, involving employees from many contractors working together. Well construction generates many documents that are shared cross-functionally between these different groups. A regulator may receive an as-drilled plat from a well planner, using surveys from an MWD operator, based on a pipe tally from a rig contractor. In this scenario, the person legally specifying the well location has likely never physically seen the wellhead or the equipment used to define the location. The regulatory database might later be used by a different operator for identifying offset wells on a nearby drilling program, further confounding matters. While document sharing is critical for successful well construction, there is often little opportunity for verification before use or transmission to another party.

A review of documents related to well construction was performed. This included plats, well plans, bottom hole assembly reports, directional surveys, and other drilling records. The examination was performed on which data was contained in these documents, how it might be verified by a third party using it, and the potential for errors to arise when the data is received or transmitted. Of particular concern were documents such as well locations and directional surveys which are not only difficult to verify but are also likely to be further shared with additional parties. These documents are frequently the basis for critical decisions related to well construction, implying a strong potential for erroneous data to be used when making those decisions.

For most of the document types investigated, there was little to no standardization on the content or format of the data presented. Similarly, when documents contained redundant data (such as a well name across a directional survey record, bottom hole assembly reports, and well plans) there was often inconsistency in how that data was presented. While in many cases the accuracy of the data may still be unverifiable, several good practices for identifying gross errors in documentation and preventing erroneous data from entering a curated database are presented. Examples include ensuring personnel are trained in the significance of the data being received and requesting redundant data whenever possible so internal cross-validation can be performed for data consistency.

Data quality processes for internal workflows have long been a focus for the industry. As more systems become increasingly connected, a similar amount of attention must be paid to external workflows, where if care is not taken data of unknown and unverifiable quality may be used to make critical decisions.
Enhancing Information Retrieval in the Drilling Domain: Zero-Shot Learning with Large Language Models for Question-Answering
Authors: Pacis F. J. , Alyaev S. , Pelfrene G. , Wiktorski T.
Published: February 2024

Finding information across multiple databases, formats, and documents remains a manual job in the drilling industry. Large Language Models (LLMs) have proven effective in data-aggregation tasks, including answering questions. However, using LLMs for domain-specific factual responses poses a nontrivial challenge. The expert labor cost for training domain-specific LLMs prohibits niche industries from developing custom question-answering bots. This paper tests several commercial LLMs for information retrieval tasks for drilling data using zero-shot in-context learning. In addition, we studied the model’s calibration using a few-shot multiple-choice drilling questionnaire.

To create an LLM benchmark for drilling, we collated the text data from publicly available databases: the Norwegian Petroleum Directorate (NPD), company annual reports, and petroleum glossary. We used a zero-shot learning technique that relies on an LLM’s ability to generate responses for tasks outside its training. We implemented a controlled zero-shot learning "in-context" procedure that sends a user’s query augmented with text data to the LLM as inputs. This implementation encourages the LLM to take the answer from the data while leveraging its pre-trained contextual-learning capability.

We evaluated several state-of-the-art generic LLMs available through an API, including G4, G3.5-TI, J2-ultra model, and L2 series. The paper documents the pre-trained LLMs’ ability to provide correct answers and identify petroleum industry jargon from the collated dataset. Our zero-shot in-context learning implementation helps vanilla LLMs provide relevant factual responses for the drilling domain. While each LLM’s performance varies, we have identified models suitable for a drilling chatbot application. In particular, G4 outperformed on all the tasks. This finding suggests that training expensive domain-specific LLMs is not necessary for question-answering tasks in the context of drilling data.

We demonstrate the utility of zero-shot in-context learning using pre-trained LLMs for question-answering tasks relevant to the drilling industry. Additionally, we prepared and publicly released the collated datasets from the NPD database and companies’ annual reports to enable results reproducibility and to foster acceleration of language model adoption and development for the subsurface and drilling industries. The petroleum industry may find our solution beneficial for enhancing personnel training and career development. It also offers a method for conducting data analytics and overcoming challenges in retrieving historical well data.

This paper will discuss the engineering process used to redesign the polycrystalline diamond cutter (PDC) and roller cone cutting structures of a Hybrid Bit in the challenging Foothills application of Colombia. The primary challenge to drill 14 3/4" section in Colombia foothills is high torque values its oscillations and vibration that produce premature damage of the PDC bits; specially while drilling Carbonera C5 formation, which has a very high abrasiveness and compressive strength (25 Ksi UCS). In addition to the traditional post-drilling analysis of the bit design, the use of an advanced polygonal mesh drilling simulation software in combination with laboratory test will be described as a key element to maximize the durability of the bit. This step of the process allows for the first-time an integrated analysis of the PDC/roller cone cutting structures all together. Analysis of the engagement balance along with the calculation of forces applied to the various cutting structure components, ultimately resulting in an improved optimization of bit performance beyond the common scenario considering the use of 4-5 PDC bits for the whole section.

A computational model, using a polygonal mesh simulation was developed for getting a deeper understanding of the PDC and roller cone interaction in the cutting structure of a hybrid drill bit; afterwards, this simulation software was calibrated with data from pressurized tests obtained in a drilling lab. Improvements of the bit cutting structure started with the ability to correlate the dull condition of the bit under several conditions of torque on bit (TOB), weight on bit (WOB) distribution and Depth of Cut (DOC). This, in turn, guided the bit design changes which were then validated by running the new design through the same simulation and achieving desirable results.

The optimized hybrid drill bit sets a footage record in the Foothills area drilling 50% further than standard PDC bits and achieving 39% more ROP than the previous hybrid bit design in offset wells. In addition to ROP and durability improvements, the original bearing – seal life was improved from 50% to 100% of effectiveness with the new design for this application in this hole size. The new design features optimized the depth of cut (DOC), the weight distribution across the cutting structure and increased stability and efficiency as well. Thus, overcoming the challenge to drill further and more efficiently through these challenging formations.

A specialized team has for the first-time optimized Roller cone structure and PDC structure together improving bottomhole drilling dynamics, performance and bit reliability for this application through the combination of robust polygonal mesh simulations of the drilling process and pressurized rock drilling tests in a drilling lab.

Rotary steerable systems (RSS) were first introduced as push-the-bit systems in the late 1990s and were drilling in manual mode sending downlinks by mud pulses downhole. The point-the-bit RSS was introduced in 2003. The first automated mode, known as inclination hold, was introduced in 2003. This was followed by vertical mode in 2004 and by hold inclination and azimuth mode in 2008. The last well profile type, the curve section, was not automated until 2020 when curve control was implemented for push-the-bit RSS. Implementing curve control for push-the-bit RSS has reduced the frequency of downlinks sent from surface and has improved the rate of penetration, thereby supporting a sustainable digital solution for directional drilling and drilling engineering. Curve control for point-the-bit RSS was introduced to the field in mid-2022 and has opened new applications for downhole automation. Point-the-bit RSS has a different steering mechanism (fixed bend) and it has the sensor offset farther from the bit, which creates challenges for implementation of trajectory automation.

In our work, we analysed several case studies and examined new application opportunities for autonomy for trajectory automation based on the field results. Until mid-2022 directional drillers sent manual downlinks to point-the-bit RSS from the surface to follow a planned trajectory and hit the target. These downlinks sent a steering ratio to achieve desired dogleg severity (DLS) and a desired toolface to turn the well if needed. By introducing downhole automation, the Directional Driller is able to send curvature commands, and the tool determines steering ratio to achieve planned DLS by applying a closed-loop algorithm to drill the trajectory. The closed-loop system minimizes the influences of variations of weight on bit, RPM, and formation characteristics on trajectory response.

Point-the-bit RSS have shown the ability to drill different curve profiles in curve control mode from 2D build to 3D build or drop. Some of the trajectories included a tangent section that were executed with DLS demand of zero. The case studies demonstrate that curve control mode has drilled entire hole sections while reducing the frequency of downlinks, increasing the rate of penetration, and increasing consistency.

Our work examined the next level of downhole automated directional trajectory control for point-the-bit RSS that is currently handled and controlled by the directional drillers (e.g., geometric and geological steering). The curve control mode minimizes the interactions with the surface and allows the driller/surface system to optimize the drilling parameters. The algorithm also minimizes the influences of variations of weight on bit, RPM, and formation characteristics on the trajectory response.
Recovery Control - Closing the Loop in Automated Control Systems

Drilling process automation has been a trending topic within the technical community, most recently discussed in SPE-212565-MS (Cayeux et al. 2023). Recovery control - specifically in the case of motor stalls - is not only integral to consistently completing automation control system execution, but also building confidence for the control system users and ultimate automation benefactors. Predicting, preventing, detecting, mitigating, and recovering motor stalls through automated recovery control solves an issue affecting most operators, contributing to additional bottom-hole assembly (BHA) damage and unplanned trips.

The recovery control system was designed with six major process control interfaces, two of which occur during on-bottom drilling: drilling while rotating and drilling while sliding. Each control interface is a means by which an external system can control the rig tools in a coordinated fashion, managing what control is currently active and ensuring the driller can ultimately assume control at any given time. The recovery control is customized and preconfigured with an observation window to execute the recovery process once the stall criteria has been breached while on-bottom drilling, sliding or rotating. The result is mitigated motor stalls that are consistently managed with a configurable automation system, less BHA damage, and no motor stall related unplanned trips - displaying both time and cost value.

After two years of testing the recovery control system internally, there were no undetected stalls, no false detections, and no unplanned trips due to motor stall, displaying detailed accuracy. The recovery control complements the process control, limit control, and manual control components of the automation control system to drill a stand effectively and consistently.

A complete and effective automation control system gives time back to the rig crew and allows for leadership development opportunities. The reliability gained through recovery control, faster than manual attempts, allows the driller to focus more time on safety and training the rig crew instead of monitoring differential pressure in the hopes of manually preventing a motor stall. In nearly all cases, stalls were detected faster with the automatic recovery control system compared to manual detection by the driller. Drillers cannot be expected to pay attention to the hundreds of potential drilling problems - a control system can.

There are systems claiming to identify motor stalls, but this recovery control is the only technology to date that actively detects and recovers the system from the stall.
Review of Design and Operation of the Integrated Riser Joints Used in Deepwater MPD Operations

Published: February 2024

Integrated Riser Joints (IRJ) have become a key component of deepwater Managed Pressure Drilling (MPD) operations. They enable the surface MPD system to be integrated with the riser, allowing for safe and fast installation and retrieval despite complexities.

Deepwater MPD integrated riser joints are made up of (a) a below-tension-ring rotating control device (BTR-RCD) to create a seal around the drill string during the drilling and tripping process. (b) an MPD annular packer that serves as an alternative sealing device when the rotating control device (RCD) or active control device (ACD) is not deployed or needs maintenance (c) a flow spool featuring valves and tie-in points for hoses facilitating the circulation of drilling fluids from downhole to surface equipment. (d) Choke, kill and boost line conduit to interface with the rigs riser joints. The instrumentation system installed on the IRJ enables real-time wellbore pressure monitoring and remote control of MPD flow line valves. The choke, kill boost conduits as well as mux line clamp locations facilitate a normal riser set up for surface to subsea blowout preventer (BOP) communications.

IRJs that are deployed for deepwater MPD installations represent a significant advancement over the systems used in early floating rig MPD operations. They are designed for efficient and safe deployment and are compatible with a variety of deepwater drilling systems. MPD integrated riser joints operate in a complex wellbore condition allowing efficient and effective wellbore pressure control, improving the safety of deepwater drilling operations. It enables real-time monitoring of the wellbore parameters allowing drilling supervisors and engineers to make timely adjustments to drilling parameters. This technical paper reviews key design considerations of different IRJ systems developed by the industry and used in deepwater MPD operations. The paper examines how the IRJ system has evolved over time due to the requirement for a more efficient method of deploying RCD and annular isolation devices in deepwater wells.

The authors provide an unbiased view on the recent developments of Integrated Riser Joint technology based on their experience and actual application of the system worldwide.
