Authors: Elkhamry Ayman , Fouda Mohamed , Taher Ahmed , Bikchandaev Eduard
Published: February 2023

Integrating the inversions of simultaneously acquired deep and ultra-deep logging while drilling (LWD) azimuthal resistivity measurements can improve the resolution of the overlapping volume under investigation and reduce uncertainty in the far field volume model reconstruction. Both are key tools for precise placement of horizontal wells, the recent enhancements in the downhole tools include surface processing algorithms and advanced visualization techniques that allow higher confidence in well placement decisions through improved understanding of subsurface geology and orientation of sand channels in real-time.

The high-definition multi-layer inversion capability of a new generation deep resistivity tool has been utilized along with the 1D and 3D ultra-deep resistivity inversion for a separate established tool, providing detailed visualization of formations both near wellbore and in the far field. Both technologies were compared in reservoirs with varying resistivity profiles and thicknesses. In addition, the resistivity anisotropy analysis from ultra-deep 3D inversion was utilized to confirm lithology around the wellbore differentiating anisotropic shale zones from other lithologies of similar low resistivity. Ultra-deep 3D inversions were processed with fine scale cell sizes and then used to validate the high-resolution deep resistivity inversion results.

The integration of multiple inversions with varying capabilities enabled resolving thin reservoir layers in a low-resistivity, low-contrast environment, providing superior resolution within the overlapping volumes of investigation of the deep and ultra-deep resistivities. Customization of the ultra-deep 3D inversion successfully enabled geo-mapping of 1-2 ft thick layers and was used to validate the high-resolution deep resistivity 1D inversion. The increasingly challenging geo-steering decision-making process in a complex drilling environment was addressed by employing the advancement in LWD technologies providing higher signal to noise ratios, multiple frequencies and transmitter-receiver spacings augmented with customized inversions providing superior results.

This paper demonstrates the added value, to identify, map and navigate thin reservoir zones. A novel workflow has been developed to improve resolution in deep and ultra-deep resistivity mapping, enabling the identification of thin laminations around the wellbore capitalizing on the latest advancements in LWD geo-steering technologies.

The continental shale oil reservoirs usually have strong heterogeneity, which make the law of fracture propagation extremely complex, and the quantitative characterization of fracture network swept volume brings great challenges. In this paper, firstly, the grey correlation analysis method is used to calculate the correlation coefficient between different parameters and microseismic monitoring volume (SRV), and the key factors affecting SRV are identified. Secondly, the relationship between key geological engineering parameters and SRV is established by using the method of multiple linear regression, and the relationship is further corrected by productivity numerical simulation method, and the empirical formula for quantitative characterization of fracture network swept volume(FSV) is established. Finally, according to the field production of big data, the fitting chart of the accumulated oil production and the FSV is established, and the production of horizontal well is further predicted according to the fitting formula. The study results shown that the main factors affecting the SRV were fracturing fluid volume, fracture density, brittleness index, pump rate, horizontal stress difference, net pay thickness and proppant amount.The FSV in the study area was positively correlated with the cumulative oil production of the horizontal well. With the increase of the FSV, the accumulated oil production increased at first and then tended to be stable, and the optimal FSV was 760 ~ 850*104m3. The prediction method was verified by the typical platform in the field to be accurate and reliable. It can provide scientific basis for the productivity prediction of horizontal wells in shale oil reservoirs.
Innovative and Tailored Refracturing to Rejuvenate the Largest Shale Gas Field of China: Case Study
Authors: Li Yuanzhao , Ming Yue , Zhang Chi , Han Rong , Guo Luhao , Zeng Yunxiang
Published: February 2023

The Fuling shale gas field in China is one of the largest shale gas fields outside of North America. After a long period of production, some gas wells showed significant production decline and an effective refracturing treatment is designed to rejuvenate production. This Casing-in-Casing (CiC) refracturing method with customized design was successfully implemented with production increase beyond expectation. It was the first successful trial of a CiC refracturing treatment on a horizontal shale gas well in China.

Bullheading (BH) refracturing with diverting balls was attempted in this field in past years, with high initial production observed. However, the production was inconsistent and declined quickly. The operator investigated and decided to attempt a CiC refracturing method in an under-stimulated candidate well. The CiC refracturing method is to cement a 3.5-in. liner in the legacy 5.5-in. casing to isolate the perforations, and new plugging and perforating (P-n-P) operations can be performed in the reconstructed wellbore. A refracturing design was customized integrating the production profile, residual recoverable reserves, and the specific 5.5- × 3.5-in. reconstructed wellbore limitation.

During the BH refracturing, the treating pressure gradually increased with the drops of diverting balls, but the proppant placement became more and more difficult accordingly. The BH refracturing was finally completed with five cycles which was less than the design. High initial production after the BH treatment was observed but it declined quickly. In the CiC refracturing, a new 5.5-in × 3.5-in wellbore was constructed successfully, and it passed pressure test for stage frac. New clusters were added between the original clusters and stimulated with more intensive fracturing treatment in the new wellbore. Dissolvable particulate diverting agent was used for even cluster initiation and fracture geometry. The pressure response of the diverting agent was obvious indicating good diversion result and new reservoir contact. The initial production recovery rate was 88.1% compared to that of the original fracturing and the production increased 819% compared to the production before the CiC refracturing, which was much higher than BH refracturing.

This case study illustrates that the CiC refracturing method is an effective method for refracturing. It overcomes the uncertainty and difficulty of proppant placement, achieves a higher intensity of fracturing treatment, and enables stimulation of the previously bypassed reservoir to improve the recovery of the well. The method has provided the industry with a new and reliable option to rejuvenate the aging wells.
A Hybrid Physics and Active Learning Model For CFD-Based Pipeline CO2 and O2 Corrosion Prediction
Authors: Yang Huihui , Lu Ligang , Tsai Kuochen , Sidahmed Mohamed
Published: February 2023

Pipeline corrosion induced from CO2 or O2 is a serious and costly hazard for oil/gas industry. CO2 and O2 are different complex corrosion processes. We developed an innovative hybrid model that combines both the first principal physics and advanced machine learning (ML) method to build a single model that can predict multiple corrosion mechanisms involving CO2 andO2. It can significantly speed up corrosion analyses in complex geometry using computational fluid dynamics (CFD). The ML prediction output was used to account for the local effects of mass transfer limitations, which requires only four variables: average inlet_velocity, pipe_ID, pipe_bend_angle and the ratio of pipe_bend_radius and pipe_ID instead of the 7 variables including CO2 partial pressure, pH value and temperature. The last three variables were found to be almost independent on the local flow variables because CFD solutions were only obtained at the macroscale level while the microscale surface variable values are solved using mass transfer limitation correlations. This new approach greatly lowered the number of CFD simulations needed to generate data for machine learning models. The hybrid model is about 106 times faster than the CFD simulation with acceptable accuracies.
Improving Frac-Plug Milling and Flowback Efficiency Through Multiphase Metering Application in Deep and Tight Carbonate Horizontal Gas Wells
Authors: Hashim Qassim I. , Ajmi Fahad M. , Sarac Sukru
Published: February 2023

Multi-stage frac completions are frequently used to increase well productivity and meet the ever-growing energy demand. Commonly, each stage is isolated with a plug and these plugs need to be milled when the well is ready to be flowed back. Milling and flowback operations require extreme vigilance and close monitoring. This paper explains the use of a multiphase flowmeter to optimize milling and flowback operations and save water in deep, tight carbonate horizontal gas wells.

Frac plug milling operations are best performed in balanced well conditions. Underbalance conditions cause unwanted gas flow with solids at surface, which will cause equipment damage, if not maanged well. Overbalance conditions result in excessive precious underground water loss and hinder wellbore clean-out. A multiphase flow meter was used at the wellhead to monitor fluid return rate during milling. By integrating coiled tubing pump rate, depth and pressure measurements with the multiphase meter readings, downhole well conditions were assessed and the milling parameters were optimized. Additinoally, flowback conditions were also measured and analyzed in real-time to optimize choke strategy to maximize water recovery and minimize flowback duration.

Multiphase meters were used during milling and flowback operations for several horizontal gas wells with multistage frac completions. During milling, both water and Nitrogen were pumped into the wellbore to lighten the hydrostatic head and avoid fluid losses while circulating for wellbore clean-out. The operation efficiency was assessed based on the return rate of individual fluids at surface. Fluid losses into the formation and reservoir influx were quantified. The multiphase meter measurements allowed the operators to adjust choke size and wellhead pressure to maintain balanced conditions, and control the water-nitrogen pump rates.

Accurately measuring oil, water and gas flow rates with high resolution also helped with determining the choke bean-up strategy to maximize frac fluid recovery for increased fracture conductivity, while minimizing the flowback duration. Monitoring the ratios of produced fluid rates helped evaluate the wellbore clean-up performance and take necessary action to increase clean-up efficiency. Changing well productivity over time was also quantified in real-time, which allowed to optimize the flowback end time with maximum achievable well productivity, without waiting to recover all the frac fluid. The data helped quantify the wellbore productivity with respect to the frac fluid recovery.

The practices explained in this paper can improve frac plug milling and flowback operations. By closely monitoring surface returns through the multiphase meter, it will preserve valuable underground water resources, maximize fracture conductivity and wellbore productivity especially in sub-hydrostatic reservoirs, which are challenging to mill.

Published: February 2023

Acid fracturing is a common stimulation technique used on low permeability carbonate reservoirs to enhance the productivity and deliverability of hydrocarbons. The success of acid fracturing treatments ultimately depends on the created fracture geometry, complexity and surface area. To maximize these parameters, it is imperative to include a fluid diversion strategy in the treatment design. The use of high viscosity fluids and solid particles is well addressed in the literature as effective diversion methodologies. In this study, the benefits of a dual diversion system composed of solid polymer-based particulate diverters suspended in a viscoelastic surfactant (VES) fluid were investigated for high temperature acid fracturing.

The degradation profile of the solid particulates was examined for different temperatures (ranging from 250 to 300°F) in different fluid systems (15 wt% HCl, spent HCl and KCl brine). The selection of fluids was also made to ensure the compatibility of the resulting diverter monomer solution with expected formation fluids. The viscosity of the VES system was examined at 275°F to ensure its thermal stability. The bridging capability of the dual diverter system was assessed using a filter press apparatus with a slotted metallic disk by measuring fluid leak-off as a function of time.

Results showed degradation rates increased with increasing temperature where a soaking time of 4 hours at 300°F was enough to fully degrade the solid particles as opposed to only 8% weight loss at 250°F for the same soaking time. Results also indicated faster degradation in more acidic environments where almost full degradation was observed in 15 wt% HCl at 250°F and 4 hours soaking time. The VES fluid system maintained sufficient viscosity for solid diverter carry with approximately 94 cP at 275°F and 100 s-1 shear rate. Bridging tests indicated the capability of the dual diverter system to completely plug the slots on the metallic disks and stopping any fluid leak-off up to 800 psi in a filter press apparatus.

This paper presents a full methodical study of an innovative dual diversion system for application in high temperature acid fracturing treatments. The paper also presents design optimization considerations in order to achieve successful diversion without causing any permanent formation damage.

Published: February 2023

In the Tarim Basin, the wellbore blockage problem of HTHP oil wells was very severe, especially in Fuman, Donghe 1 and Yudong 7 oil fields. The total number of blocked Wells is 95, Over 24% oil wells have organic solid phase plugging problem. More than 64% of the Wells in Donghe 1 oilfield were blocked, resulting in difficulties in testing, wellbore blockage and surface pipeline burst, affecting annual production of 8,500 tons.

In this paper, a fast analysis method of blockage was established, and an organic solid phase deposition test device was innovated. The law of solid phase blocking under different reservoir conditions, development modes and crude oil properties was systematically analyzed. The dynamic prediction model of organic solid phase blocking was established to realize the visualization prediction of blocking position, and the unblocking measures technology of organic solid phase blocking was formed to comprehensively solve the organic solid phase blocking problem in oil Wells.

It was shown that the blockages in the Fuman carbonate reservoirs were dominated by wax-asphalt organic compound and sand burial, and t he gas injection development in Donghe 1 Oilfield is dominated by asphalt deposition, while that in Yudong 7 Oilfield is dominated by asphalt and wax plugging. Gas injection extraction, crude oil composition change, pressure drop and sand production are the main factors of solid phase blockage, and organic solid phase blockage exists in "wellbore + reservoir near the wellbore "; The dynamic prediction model of composite plug deposition is established to realize the "visualization"of plug location and degree, and the prediction accuracy is ≥ 80 %. The efficient unblocking agent have been developed based on the understanding of the blockage composition, to achieve high-efficiency dissolution of the blockage (the dissolving rate 90%) and the effective inhibition (85.84%). Based on the understanding of the blockage law, 4 sets of unblocking processes had been developed with "plugging degree" and "whether there was a squeeze channel" as the main considerations, For the first time, the "system blockage unblocking "design method based on the composite plugging mode of "wellbore + reservoir near the wellbore " is proposed, which realizes the efficient plugging removal. The field application of 477 wells improves the success rate of reproduction from 53 % to 100 %, and effectively reduces the risk of plugging.

This successful experience could provide guidance for blockage treatment in other oil fields with asphalt deposition and organic solid plugging such as wax.

Published: February 2023

Stuck coiled tubing (CT) is a main operational risk leading to delays, deferred production, or even loss of a well. Despite general commonalities, each CT recovery can face unique challenges including managing high pressure, working under limited spatial or lifting constraints, establishing well control, or handling a cable inside the CT.

This study consolidates learnings and proposes a general workflow for a basic stuck pipe scenario, rig-up, recovery pressure control equipment and well control, CT free point evaluation, bottomhole assemblies (BHAs) and workflows for cutting and freeing the CT pipe downhole, and recovery of the CT at surface. A consolidation of published case studies provides specific examples of the hardware, workflows, and operational considerations. In addition, presentation of a recent case study extends the discussion to the challenges introduced by the presence of a cable in the stuck CT and its respective solution.

This case study reviews the planning and execution of a CT recovery, including the use of decision trees to guide the decision-making process. It details fit-for-purpose hardware for safely anchoring the cable; packoffs for accessing, tensioning, and recovering it with slickline; an opening for deploying the wireline cutting BHA; and valves for pressure testing and well control. That workflow successfully freed 6,818 ft of stuck CT and allowed recovering the pipe without a workover rig on location, eliminating 11 days of rig time during subsequent tubing pulling. This is the first documented such recovery case worldwide based on a thorough literature review.

Authors: Maut Partha Protim , Prakash Yerra
Published: February 2023

Gas lift is the major artificial lift method for the wells of brownfields in the Upper Assam Shelf Basin. It is the best suited method for maintaining and extending the current production rate of the fields. In this gas lift optimization endeavour, we have selected Hapjan field, one of the brownfields of the Upper Assam Shelf Basin. This study comprises problem troubleshooting and optimization of 15 intermittent gas lift wells.

In the Hapjan field, intermittent gas lift wells operate with surface intermitters, as well as choke control intermittent lift in a closed rotative gas lift system. During the course of this project, all surface and subsurface diagnostic tools suitable for intermittent gas lift well optimization are utilized with special emphasis on pressure and temperature surveys. Tools and methodologies used are as follows: Surface recordings of tubing and casing pressures.Acoustic well sounding devices.Determination of optimal gas-lift gas injection rate.Multi-rate test interpretation.Gas lift surveillance software.Subsurface pressure and temperature surveys.

Subsurface pressure and temperature survey allows pinpointing of many malfunctions and provides a complete evaluation of how the well performs.

This paper presents an exceptionally detailed procedure for performing and analyzing a subsurface pressure and temperature survey in intermittent gas lift wells. In this type of subsurface survey, tandem Electronic Memory Gauges (EMG) are run in the well under flowing conditions while the well is being tested. In addition, static measurements are conducted where, once the EMG is run to depth, it remains there until the bottom hole pressure approaches the static value. When dynamic and static downhole surveys are correctly performed and analyzed, the following engineering considerations about gas lift wells can be gathered: Point of operation.Multi-point injection.Operating valve performance.Optimum cycle time.Productivity index.True fluid gradient in the production tubing.Dynamic fallback.Static Fluid Level.Static reservoir pressure and other reservoir properties.

The paper emphasizes the results of the surveys and the detailed adjustments to the wells operating mode based on well performance analysis. A 11% increase in production was obtained by implementing the survey results in 15 wells in the Hapjan gas lift field.

A great potential for low investment and rapidly increasing production and development of the reserve lies in the optimization of gas lift wells. As a result of this project, we have gathered valuable engineering experience that shows gas lift well optimization can substantially increase production in brownfields in the Upper Assam Shelf Basin and also other exploration and production (E&P) companies throughout the world.

Point-Counterpoint is one of the strategies that can be used to stimulate students and make them free in reading. This study is conducted to reveal the significant difference in reading ability under Point-Counterpoint strategy and conventional technique in class seven students at SMP Negeri 1 Batauga, South Buton regency. The design of this study was a quasi-experimental method. The sample was taken using cluster sampling, in which took class VII-F was selected as an experimental group and class VII-E was a control group. The instruments used were a pretest and a posttest. The results revealed that the average score for the pretest in the experimental group was 47.83, while the average score in the control group was 34.77. The average score for the posttest in the experimental group was 71.13, while it was 58.62 in the control group. Those scores indicated that the students had good reading ability in the experimental group, while the students in the control group had moderate comprehension in reading. The requirement testing outcome informed that the data had a normal distribution and were homogeneous. The hypothesis testing indicated that the tcount was 4.489 and the significant score was 0.000. Both results meant that the Point-Counterpoint strategy was significantly different from a conventional method toward students’ reading comprehension.

The people of Kerala have suffered the worst natural calamity in the form of heavy flood in 2018 and this continued for a week. The flood and the landslide had created a havoc in the agricultural sector of Kerala. The worst affected sector in the vagary of nature was the plantation sector. The industry lost around Rs. 3.382 crore due to heavy floods (CDS). The floods and the landslide had a major impact on the major planation crops including rubber, tea, coffee and cardamom. Among the different districts, Wayanad was the worst affected district along with Kottayam and Pathanamthitta. In the given context, this study is an attempt to analyse the economic impact of floods in the plantation sector in Kerala. The study found that the farmers are facing the worst financial crisis due to low price and high cost of production. The major problems faced by farmers are the inadequacy of assistance, reduction in yield and lack of pure water, delay in getting support, repayment of the loan and so on.

India is an agriculture-based country and the agriculture product is highly influenced by the Southwest monsoon. Forecasting of monsoon is of prime importance for planning to select appropriate Kharif crops and their varieties to minimize crop losses. Many Indian scientists have proposed sciencebased techniques while local traditional farmers have used indigenous methods to forecast weather conditions and predict a likely behaviour of the Southwest monsoon. However, predicting the Southwest monsoon pattern remains the most challenging task till date. In the present study, a methodology is developed to predict the Southwest monsoon for sub-regions of Saurashtra (India) based on the observation of some of the local factors consisting of observation of local weather, type of wind and its direction, heat waves, astronomical parameters and cloud type pattern. The predicted average rainfall was found 860mm which is nearly 20% less (1055mm) for the year 2019.The results show that the methodology under predicted the rainfall and provided consistent outcomes. It performed well in R3 sub-region and poor in R5 subregion. It will be useful to the farmers of the study region in planning and selection of appropriate crops and its variables at a definite sowing time to secure Kharif production.
Landslide Vulnerability of Urban slums: Case of Warje Slum, Pune, Maharashtra
Authors: Gokhale Vasudha , Joshi Deepa
Published: February 2023

The rapid urbanization in developing countries contributed to the severity of urban environmental hazards such as slope failure and flooding. In addition, heavy rainfall or alterations to natural environmental characteristics trigger the incidence of hazards such as landslides where local topographic conditions often exacerbate the vulnerability of the built environment. Landslide causes numerous fatalities and financial damage to millions worldwide and India is no exception. In most of the Indian cities, the physical expansion during the past few decades has resulted in increased vulnerability, with the occupation of hill slopes subject to instability. Therefore, the impact of physical characteristics of the environment and human interventions needs to be examined in assessing urban vulnerability. This study examines the vulnerability of urban settlements to landslide risk with Warje Slum, Pune, Maharashtra as a case study. It attempts to understand better the causative factors of landslides and their impact to suggest ways for better disaster management to save life and property in the future.
Computer Assisted Drug Design of AITC for Treatment of Cancer: A Combined Molecular Target Identification Study and Drug-Target Prediction

Drugs can influence the whole biological system by targeting interaction reactions. However, current databases have minimal drug target information and only a few are validated. This emerges a need to develop new drugs that predict true interaction pairs with high accuracy. Currently, network pharmacology has been used in identifying potential drug targets for allylisothiocyanate (AITC) and in predicting the spread of its activity toward bladder cancer whereas the mechanisms of isothiocyanates remain largely undefined. In this study, we present a computational method to predict targets for AITC. Results showed 13 differentially expressed hubs confirmed by Cytoscape (3.7.2). We further observed that the obtained targets were found to involve a type of Ontology of classification- molecular function, cellular component, biological process and protein class. Pathway enrichment was done by DAVID. This study identifies key genes and pathways involved in bladder cancer which helps us to understand the progression and molecular mechanism underlying bladder cancer. The obtained key genes may serve as active therapeutic targets for bladder cancer treatment. AITC may directly regulate several biological processes and their genes in bladder cancer.

Cyanobacteria are simple, photosynthetic, prokaryotic blue-green algae. They can thrive in fresh water, terrestrial, glacial, aerial, brackish and marine regions. Cyanobacteria have been exploited in recent decades due to the presence of compounds with potential activity like pigments, vitamins, proteins, carbohydrates, minerals etc. These potential compounds have valuable applications as pharmaceuticals, nutraceuticals and cosmeceuticals and also as health supplements. This review focuses on the phycocyanin pigment of cyanobacteria and its pharmaceutical applications. Phycocyanin is a blue-colored pigment protein that is abundant in cyanobacteria. Phycocyanin is exploited due to its antioxidant properties, antidiabetic, anti-inflammatory and anticancer activity. This pigment can be used as a nutrient supplement in order to treat age-related diseases and other oxidative stress-related diseases.
