Published: February 2024

Macrozoobenthos is a sedentary aquatic biota and is often used as a bioindicator for assessing water conditions. Therefore, this study aimed to investigate the species diversity of the macrozoobenthos and to analyze the heavy metal contamination inFaunus aterin the Rasian and Asahan estuaries in Aceh Province, Indonesia. The sampling was carried out in July 2022 on a squared transect of 1 m × 1 m for the collection of macrozoobenthos samples at random locations. The results showed that there were 17 macrozoobenthos species from both locations, of which 14 species were found in the Rasian River estuary and seven species in the Asahan River estuary. The diversity index of macrozoobenthos was in a moderate category.Terebralia sulcatahad a higher density in the Asahan River, whileF. aterhad a higher density in the Rasian River. The results of the heavy metal analysis in theF. atersample showed that this macrozoobenthos was contaminated by mercury, cadmium, and lead, of which the concentration of mercury exceeded the threshold limit, and they are, therefore, not safe for consumption.
Foreign ownership and gender differences in pay: causal evidence from a sample of Polish workers
Authors: Taylor Larry W. , Hyclak Thomas J. , Sedlak Piotr , Adamchik Vera A.
Published: February 2024

The study attempts to estimate the causal relationship between foreign company ownership and wages that is driven by ownership per se, and not by observable or unobservable worker and firm characteristics. We employ proprietary data from surveys conducted by Sedlak & Sedlak, a major Polish HR consulting firm, with our pooled cross-section data set comprising over 300,000 men and 250,000 women working in the Polish labor market between 2013 and 2017. The foreign-firm wage premium is estimated by several techniques, ranging from ordinary least squares and two-stage least squares to a recently developed frequentist RX-2SLS econometric procedure that relaxes IV assumptions via the exclusion restriction. Our major findings are: (1) regardless of gender, Polish workers employed by majority foreign capital firms earn a significant wage premium; and (2) the foreign-firm wage premium is substantially larger for women, suggesting that the wage policies used by foreign-owned firms in Poland have an equalizing effect on the gender wage gap.

Authors: Ghosh Anindya , Kumar Brajesh , Sharma Sushila , Chaudhary Vinay Kumar , Sarkar Rajan
Published: February 2024

Temperature measurement and transmission of a signal safely to the control room for further processing is important for the process industry. In this paper, a modified head-mounted temperature measurement system using a thermocouple with opto-isolation has been developed. Here, the thermocouple is connected to the terminals, mounted on the ceramic base in the head of the thermo-well. It consists of two signal conditioners for thermocouple and AD590, both signal conditioning outputs applied to a summer circuit. The output of the summer circuit which is in the range of 1.73–3.43V, adjusted by a signal conditioning circuit, is applied to the middle electrode of Mach-Zehnder interferometer (MZI). MZI produces normalized optical signals according to the variations in temperature. These optical signals are then transmitted to the control room safely in the inflammable process industry. The transmitted signals are demodulated in the control room and then sent to the PC through an Opto-isolator circuit and DAS card. The necessary theory as well as mathematical equation has been derived. The experimental and simulation results are reported here.
So much more than news: Revisiting press epochs from an explorative study of non-news genres in Danish newspapers, 1918–2018
Authors: Willig Ida , Bengtsson Mette , Blach-Ørsten Mark , Jørndrup Hanne
Published: February 2024

Newspapers are so much more than news content. However, the history of journalism is typically told through studies of news genres or news epochs. In this article, we test the theory of three epochs of Danish press history in an explorative study of non-news genres, as exemplified by letters to the editor, editorials, and “celebratory items” on birthdays and deaths. Through an investigation of newspapers from 1918 to 2018, we demonstrate how these non-news forms were established in the first half of the twentieth century, were institutionalised during the period after World War II, and have been transitioning over the past two decades. This confirms the theory of the partisan press epoch, the omnibus press epoch, and the segment press epoch in Danish press history. At the same time, this study expands our understanding of these three press epochs by showing how the non-news genres provided in printed newspapers are important in the construction of readers as a class in the partisan press period; as a population in the omnibus press period; and, most recently, as elites in the segment press period.

Authors:   , Cirovic Stefan
Published: February 2024

Non-invasive healthcare technologies are increasingly pivotal in research anddevelopment due to their affordability and the convenience they offer to bothhealthcare recipients and providers. Alongside traditional non-invasive methodssuch as ultrasound imaging, a variety of innovative non-invasive devices havebeen developed. These include cardiovascular diagnostic systems, bioimpedancebasedscales, and various types of analyzers. These analyzers, which can be fluidlessor fluid-based, are capable of measuring not just physical parameters of thebody but also key biomarkers like glucose and lactate. This comprehensive andtransdisciplinary thesis encompasses three distinct yet interconnected segments:1) Advanced ultrasound imaging (Papers I and II): The first explored vortexformation time in female athletes and the second detailed investigations of thesuperficial venous systems of apparently healthy volunteers.2) Validation and application of commercially available fluid-less bloodanalyzers (Papers IV-VI). These papers focus on non-invasive blood glucosemonitoring (Paper IV) and the general use of non-invasive healthcaretechnologies among female participants from socioeconomicallydisadvantaged areas (Papers V and VI).3) Design and testing of novel, fluid-based sensors, and biosensors (Papers II andIII): Paper II delves into biosensing of viruses, and paper III deals withcontinuous ex vivo glucose sensing in human blood using an enzymatic sensorin a vein replica.Each of these segments contribute to the broader understanding and advancementof non-invasive healthcare technologies, highlighting the significant role suchtechnologies play in modern healthcare research. The thesis's transdisciplinaryapproach, spanning from advanced imaging techniques to the development ofnovel biosensors, exemplifies the dynamic and evolving nature of medicaltechnology research.

Published: February 2024

Introduction. Massive perioperative blood loss that accompanies major surgical interventions is a specific critical condition, the  pathogenesis of which is dominated by severe hypovolemia, anemia, and threatening coagulopathy in combination with powerful shockogenic sympathoadrenal stress. Both massive blood loss itself and massive transfusion are associated with a significant risk of serious complications, including death. It is worth noting that information on the survival of patients after replacement of several circulating blood volume (CBV) is limited, and most of the articles are devoted to adult patients with highly traumatic surgical interventions.

The objective was to present the experience in managing the patient with blood loss of more than 5.5 CBV according to the MT protocol adopted at the Research Institute of Pediatric Oncology and Hematology. The 3-year-old patient underwent surgical intervention in the following volume: median laparotomy, nephradrenalectomy on the right (lesion 10–15–20 cm in size), paracaval and aortocaval lymph node dissection (conglomerate 7–8 cm in size), resection of S5-S6-S7 liver segments, resection of the right domes of the diaphragm. During the surgical  intervention of 440 minutes (7.3 hours), the total blood loss was 5.5 CBV (5.500 ml).

Results. After surgery, he was transferred to prolonged assisted ventilation of the lungs, the duration of which was 2 days. On the 3rd day after the operation, adjuvant polychemotherapy was started. 17 days after the operation, the patient was transferred to the specialized department for further treatment. The patient was alive for a year after surgery.

Conclusion. Maintenance of homeostasis, normothermia, normocoagulation through basic infusion therapy with balanced crystalloid solutions, targeted transfusion therapy with the introduction of fresh frozen plasma, transfusion of donor platelets and donor  erythrocytes/autoerythrocytes during anesthesia in the child with extremely massive blood loss, contributed to early post-anesthetic rehabilitation,  provided the opportunity to continue special treatment in the intensive care unit.
Patient advance care planning in end of life care: international data review
Authors: Sergienko S. K. , Reznik O. N.
Published: February 2024

Intensive care allows maintaining the vital functions of patients with irreversible brain damage for a long time. Under appropriate criteria, human death is determined by brain death, but most patients die after an undetermined period from the inevitable complications. Our legislation does not allow stopping futile treatment and letting a hopeless patient die naturally. In Russia, patient’s right to autonomy and self-determination is fulfilled through the informed consent or refusal to medical intervention. An adult comatose patient with a brain damage isn’t able to make this decision and sign the consent or refusal form, doesn’t have a Health Care Agent, and the medical council makes decision. In this situation, proper treatment is performed regardless of the prognosis. Even if the patient would prefer to die with dignity and comfort, his right to decide cannot be realized.

In many countries of the world, there has long been a practice of the advance care planning in case the patient is unable to decide. A person signs advance directives, appoints a Health Care Agent for the medical decision-making. Based on the documented preferences of the patient and communication with his surrogate, doctors can limit the life-sustaining treatment for a hopeless patient and allow him to die. The presented analysis of international data provides basic information for the discussion of the possibility of advance care planning in our country.

Authors: Bender Özenç Damla , Öz Kökten
Published: February 2024

In this study, the effects of hazelnut husk on growth, quality parameters, and nutrient content of primrose were evaluated. For this purpose, thirteen different growing media were prepared by mixing fresh hazelnut husk (FHH) and mature husk wastes (MHH) with peat at different rates. Some physical and chemical properties of the media and nutrient analyses were made for the nutritional status of the plants. The study was carried out in greenhouse conditions with four replications according to the randomized plot design. The aeration capacity and easily available content of the growing media is within the limit values, the medias with 50% FHH and MHH were prominent in terms of air-water balance. The effect of the medium on the aesthetic appearance, total shoot, leaf, and flower number of the primrose was not significant, but it was effective on flower weight, plant height, and root fresh-dry weight. In terms of plant root-shoot development, 30% FHH and 50% MHH were prominent. The media have caused significant differences in nutrient concentrations in primrose except for nitrogen, phosphorus, and copper. The leaf phosphorus concentration was high, nitrogen and potassium concentrations were within the limit value range, iron was sufficient, and manganese and copper were insufficient, while zinc was mostly lower than limit values. When all the data are evaluated, 50% ratios of hazelnut husks can be recommended in primrose cultivation and hazelnut husk can be evaluate in ornamental plant cultivation as a growing media.

Authors: Fadıloğlu Eylem Ezgi , Ergezer Haluk
Published: February 2024

The study was carried out to develop chicken patties by incorporating acorn flour as a meat replacer at 3%, 6%, and 9% levels in the formulation. For this purpose, the chemical (moisture, protein, fat, ash), pH, thiobarbituric acid (TBA), and color analyses in the raw and cooked chicken patties were analyzed. In addition, the cooking properties (cooking yield, diameter reduction, thickness reduction), functional properties (moisture and fat retention) and sensory properties were examined on cooked chicken patties. There were significant changes in the chemical, cooking, functional, and color properties of chicken patties with acorn flour. The moisture and protein values decreased, in both raw and cooked samples incorporated with acorn flour but fat level increased only in raw acorn flour added samples. Lightness (L*) and redness (a*) values decreased significantly. The addition of acorn flour caused an increase in b* values of raw samples and a decrease in cooked samples.  Acorn flour was not effective in preventing lipid oxidation. The addition of acorn flour contents in chicken patties improved functional and cooking properties, decreased cooking loss, and increased moisture and fat retention. The use of acorn flour improved the quality parameters of patties, but the addition of acorn flour resulted in a darker color in patties.  The use of acorn flour in chicken meatballs did not negatively affect sensory properties except color. In conclusion, acorn flour can be used as a filler and binder in chicken patties.

Published: February 2024

Proper nitrogen (N) management is vital for gaining potential yield benefits of a variety. Adjusting transplanting time enables the plant taking benefit from natural conditions favorable for its growth. In light of these, an investigation was carried out in the Boro season at the Agronomy Field Laboratory, Bangladesh Agricultural University from November 2022 to April 2023 to investigate the impact of various transplanting dates and N levels on the yield of Nizershail rice. The study involved four dates of transplanting viz. 16 December, 31 December, 15 January, 30 January and four nitrogen (N) levels viz. 0, 50, 100 and 150% of the recommended dose (RD) of N from urea where the recommended dose was 90 kg urea per ha. The trial was replicated thrice using Randomized Complete Block Design (RCBD). Results showed that the tallest plant, the uppermost grains/panicle and 1000 grains weight were detected in 16 December transplanting and the maximum grain yield was observed in 31 December transplanting. For N, total tillers and effective tillers/hill, grains/panicle, the highest grain and straw yields were found from 100% RD of N and the highest panicle length and sterile spikelets/panicle were found from 150% RD of N. In interactions, the maximum effective tillers/ hill and straw yield were observed from 100% RD of N in combination with 15 January transplanting. The maximum 1000 grains weight and the grain yield were obtained from 100% RD of N in combination with 16 December transplanting. From the result, it may be assumed that to get the maximum yield of Nizershail rice in Boro season could be transplanted between 16 December to 15 January with 100% RD of N from urea.

Authors: Öztürk Mustafa , Can Aysen
Published: February 2024

Kaymak is a traditional Turkish dairy product with high fat and moisture, and low protein content. According to the Turkish Food Codex, Kaymak must contain at least 60% milk fat. Obesity is one of the most important health problems of our era, and there have been many initiatives to reduce the fat content of ready-to eat consumer products. In this study, the effect of emulsifying salts (trisodium citrate, disodium phosphate and tetrasodium pyrophosphate) on texture and sensory properties of reduced fat Kaymak (30% fat) was investigated. Emulsifying salts were used in the manufacture at two different concentrations (5 and 10 mM) and a reduced fat Kaymak without emulsifying salts was used as control. Manufacturing reduced fat Kaymak with 10 mM trisodium citrate and 5 mM tetrasodium pyrophosphate increased Kaymak hardness. Samples manufactured with 10 mM trisodium citrate exhibited the highest sensory quality, while Kaymaks manufactured with 10 mM tetrasodium pyrophosphate received lowest sensory scores. In conclusion, 10 mM trisodium citrate successfully improved textural and sensory properties of reduced fat Kaymak.

Gdy opisuje się oryginalną fasadę kościoła w Zabrzu oraz jego plan odwołuje się do historycznych stylowych inspiracji oraz języka symbolicznego zastosowanego w kościele św. Józefa gdy wszystko to służy dobru architektury i liturgii. Uwzględnia się jednocześnie inne realizacje sakralne Dominikusa Böhma oraz innych działających w owym czasie architektów. Dotyczy to analizy wnętrz kościelnych o układzie liturgicznym centralnych, podłużnych i tego wszystkiego co przybliża ku sobie w architekturze sakralnej, wspólną drogę historii, teraźniejszości i przyszłości.
Odnowa czy reforma liturgiczna w świetle teologii Benedykta XVI
Authors: Litawa Karol
Published: February 2024

Zagadnienie odnowy czy reformy liturgicznej wpisuje się w pontyfikat wybitnego teologa i miłośnika liturgii papieża Benedykta XVI.  Sam papież określił ją jako „reforma w ciągłości” (la riforma nella continuità), natomiast w ocenie współczesnych teologów - „dynamiczną hermeneutyką ciągłości”. Zarówno w nauczaniu Benedykta XVI, jak i w jego osobistej trosce oars celebrandi, a szczególnie w jego reformie liturgicznej wyraża się nieustanne zabieganie o wcielanie w życie Kościoła i wszystkich jego członków zasadylex orandi – lex credendi. Ta zasada wzajemnej zależności między liturgią a wiarą Kościoła ma prowadzić do ukazania ciągłości sprawowanego kultu oddawanego Bogu.
Ars celebrandi – niespełniony postulat odnowy liturgicznej Soboru Watykańskiego II?
Authors: Potoczny Mateusz R.
Published: February 2024

Odnowa liturgiczna Soboru Watykańskiego II zdefiniowała szereg postulatów, które w zamierzeniu ojców miały nadać nowy wyraz liturgii Kościoła rzymskiego. Owe postulaty określone zostały przede wszystkim w konstytucji o liturgii świętej Sacrosanctum Concilium, która stała się dokumentem założycielskim późniejszej reformy. Wśród rzeczonych postulatów część została sformułowana w sposób precyzyjny, natomiast inne – nie zapisane explicite – wynikają z ducha proponowanej reformy. Jednym z tych nie wyartykułowanych wprost postulatów jest troska o kształt sztuki celebrowania (ars celebrandi) liturgii. W niniejszym studium autor stara się wyartykułować soborowe wskazania dotyczące tej problematyki i z perspektywy sześciu dekad dokonać ewaluacji ich recepcji w liturgii Kościoła rzymskiego.
Customized Matrix Acidizing Simulation for Optimum Acid Placement in Smart Completion Applications Resulting in Homogeneous Acid Placement, A Case Study Review
Authors: Baioumy Basma , Prossaird Sylvain , Rivas Jose , Mustafa Hammad
Published: February 2024

Maximum Reservoir Contact (MRC) wells with up to 10,000 ft laterals are drilled to increase well productivity. It is common to complete such wells with smart liners & inflow control devices (ICDs) for effective stimulation and rate distribution along the horizontal drain, raising the need for high-rate acid stimulation to effectively cover the full drain length. This paper will review the challenges and their remedies in designing high-rate matrix acidizing along with software modeling solutions.

For effective acidization through ICDs, a model was created using simulation software to match the injection profile, pressure drop, and injection rate across each ICD. The simulation model was developed to account for ICD and smart liner completions considering several parameters including, the several number of discharge coefficients for each segment, well completion, reservoir properties, fluid rheology, and the actual treatment fluid properties. After thorough validation, a unique model was customized to match the properties of each well, resulting in maximizing the acid treatment pumping rate, without risking formation breakdown, while assuring homogenous acid distribution across the lateral section.

The pressure outcome of complex smart liner/ICD completion is first validated by comparing available injection profiles of water and perforation friction losses. Based on the results from several carbonate horizontal wells, the mentioned best practices and customized simulation software have proven their capability of simulating the actual pressure profiles throughout the wellbore. It was observed that the pressure profile was affected by several parameters, out of which, the well completion was a main contributing factor. Other parameters affecting the pressure profile were fluid rheology, reservoir rock/fluid properties, and skin effect. The study concluded that using the customized simulation model enabled the achievement of a good match between the simulated pressure profile and the actual pressures that were recorded during the pumping operation. The paper also revealed in detail the important elements that were essential to design effective matrix acid stimulation treatment through smart liner aiming to homogeneously distribute the acid treatment across the lateral section. In conclusion, the study revealed that the customized simulator achieved an accuracy of 95%, which was a remarkable improvement compared to conventional simulations. This paper introduces, for the first time, a customized acid stimulation model for treatments deployed in smart ICD completions. The model was able to match the actual treatment placement with a remarkable accuracy exceeding 95% which helped to optimize the matrix acid treatment and deliver the job more efficiently.
Assessing Different Formation Evaluation Methods to Distinguish Low Resistivity Pay in Carbonate Reservoirs
Authors: Alshuwaikhat Ali , Mostefai Ilies , Al-Nasser Mamdouh
Published: February 2024

Low resistivity pay is one of the main challenges that exist in carbonate reservoirs with complex pore structure. When hydrocarbon charging occurs, it displaces water in larger pores with lower entry pressure, leading to a complex fluid distribution. As resistivity logging is based on how easily electrical current tends to flow through formation, a rock made up of micro pores filled with water will exhibit a misleading low resistivity reading that can highly influence fluid saturation and formation evaluation when using simple logging tools such as resistivity.

The objective of this paper is to provide an assessment of two different formation evaluation methods: resistivity logs and capture cross-section (formation sigma) across low resistivity pay intervals. The workflow includes a thorough evaluation of water salinity across the targeted field. Then, candidates were selected to compare results between the different methods to evaluate hydrocarbon and water saturations, as well as bound fluid volume. These results were then benchmarked and validated against formation testing and sampling (FTS) and surface production data to identify level of accuracy and limitation of each technique.

Results of this study show that sigma-based saturation can be considered as reliable across LRP intervals in simple rock mineralogy carbonate reservoirs, and it is recommended to compliment triple-combo logs to flag such challenging zones. The computed hydrocarbon and water saturation is based on set sigma values for each fluid type and lithology, which are inputted into the volumetric equation. On the other hand, resistivity log tends to underestimate hydrocarbon saturation using conventional Archie's equation. NMR logs and core analysis provide an additional knowledge of porosity distribution and existence of micro-porosity in the formation. Fresh water injection, as well as any variation in formation salinity would highly impact both saturation computation methods.

Combining sigma and triple combo logs would lead to increasing engineers’ confidence in precise horizontal well placement in hydrocarbon-bearing low resistivity intervals, as well as accurate identification of fluid contacts in vertical wells. Additionally, this could lead to a significant optimization in unnecessary sampling jobs and completion designs and its associated costs.

Commercial development of large green field unconventional projects with concurrent late-stage appraisal and initial development drilling is fraught with challenges. While the resource may be laterally extensive, extracting the resource efficiently is an engineering challenge that involves decision making at multiple stages to sequence and stack segments so as to maximize value and minimize risk. In large unconventional developments, allocating capital for appraisal and development sequencing benefits from a structured stochastic approach addressing risks and uncertainties to remove subjectivity. This paper illustrates the application of stochastic methods to guide management decision making during initial project development.

Large unconventional plays show spatial variability in fluid composition and productivity. A good appraisal program ensures sufficient wells are drilled, completed and tested to understand this variability. Learnings from such programs combined with learnings from analogue wells aid in categorizing PVT and well performance variability to identify priority areas of focus. Based on this analysis, representative models are determined for fluid windows incorporating a range of expected well deliverability. Using a structured stochastic approach, these representative models leverage a bespoke economic workflow integrating multiple uncertainties, constraints, costs and risks through a stochastic method. The workflow shown in this paper is based on synthetic data.

Based on a range of outcomes, decision making metrics such as probability of commerciality, expected monetary value and peak funding exposure are calculated integrating value of information criteria. The key output from this integrated workflow enables prioritization of focus areas for appraisal and development including stacking and sequencing of resource segments to ensure effective capital allocation and supporting optimum development value.

This paper highlights the benefit of applying a stochastic economic method to guide management decision making at the early stages of project development. The aim is to support management with an unbiased scientific approach which considers multiple uncertainties. This method helps prioritize appraisal and development options with multifaceted criteria for decision making and capital allocation.

The normal approach to fracturing optimization in any tight formation involves comparing the production from multiple wells after one or two controlled changes to the design parameters. This approach might not adequately consider the importance of each factor nor disclose hidden relationships between them. The new approach presented in this paper involves applying machine learning to optimize fracturing designs by understanding factors affecting production and by predicting production using a data set of historic wells’ geological, fracturing and production parameters.

This approach proposed here, when applied to our development asset, increased the prior frac optimization parameters by multiple factors, including geological properties, fracturing parameters, and production data, which will also be applied to predict gas production. The data from 110 wells containing Shan2 and Benxi reservoirs were prepared, trained, and analyzed. Then, 14 trial algorithms were ranked by R2 scores and the best one was used to perform a sensitivity analysis between the factors and production. This result can be used to optimize design parameters and achieve the most economic design.

Randomly chosen training and testing data sets were used to compare algorithms. Based on R2 scores, a gradient-boosted tree algorithm applicable for both reservoirs was determined to be the best. This algorithm showed that effective thickness and pumping rate have had the greatest impact to gas production from the Shan2 reservoir production, but gas saturation and proppant concentration are the most important for wells producing from the Benxi reservoir. These factors then become the main adjustable parameters in the fracturing design.

These results were then applied to guide hydraulic fracturing designs of six new wells. The final designs were based on optimizing both production and operating costs. Well testing showed that optimized designs achieved an overall 27% increase in absolute open flow compared with standard designs. Optimized designs incur marginally higher costs, this is offset by a 33% increase in 2 years of cumulative production, which represents an overall economic improvement in this development scenario.

This principal benefit of the machine learning approach is to create a robust decision making for adjusting hydraulic fracturing designs based on production and economics. In addition, prediction accuracy improves over time with the addition of new wells and longer production history. Finally, this novel approach is proven to maximize gas well productivity and to optimize materials and logistics.
Evaluation of Real-Time and Post-Drilling Petrophysical Data Acquisition Impact on Wellbore Stability and Mechanical Rock Integrity

Published: February 2024

The objective of this paper is to examine filtrate and mud solids invasion effect on wellbore stability and rock mechanical integrity. A stable wellbore depends on the mechanical and chemical interaction between the wellbore fluid and the walls of the wellbore. Excessive wellbore pressure can cause lost circulation and low pressure of the wellbore can cause blowout or collapse. Multiple factors affect mechanical integrity of the rock including the time at which the acquisition of rock mechanical data was taken in the subsurface. The impact of invasion is measured by the exploitation of real-time and post-drilling petrophysical data. A thorough investigation of invasion and its effect on rock mechanical properties is performed to establish a full understanding of the association between time dependency and rock integrity. A mechanical earth model (MEM) is built utilizing petrophysical data acquired in both real-time and post-drilling. Mechanical properties are then cross checked with core measurements to examine the accuracy of the results. The effect of invasion is then highlighted showcasing the time dependency effect on both wellbore stability and rock mechanical integrity.

Leveraging real-time and post-drilling petrophysical data across abrasive sandstone formation is key to investigate invasion effects. The effects were witnessed in the readings of resistivity. Separation of deep, medium, and shallow resistivities were observed highlighting the invasion effect due to the time passed after the drilling process and before logging the section. When it comes to invasion effects on strength of the rock, an (MEM) was run on a well with both LWD and wireline acoustic data. Fracture point was analyzed for the effects of invasion. A data comparison is highlighted showcasing the effect of time on the integrity of the rock. Capillary force and osmotic pressure effects are examined and cross checked with the logged data and wellbore stability impact. This paper examines the direct impact of invasion on the mechanical properties of the rock along with wellbore stability. Complex formations can be problematic in lithology during the drilling operation where it might be capable of creating issues such as stuck pipe. The geomechanics of borehole stress has a direct impact on the hazards and problems encountered during drilling operation which causes inefficiency in terms of time and cost spent operationally. The full understanding of invasion effect is a potential solution to such issues.
