Published: March 2023

Abstract
Corrosion Management (CM) along with Risk Based Inspection (RBI) are inseparable elements of an Integrity Management System (IMS). Digital integration of CM and RBI is vital for the optimization of an IMS. Several market available software programs are developed to deliver this integration by interlinking the modules in a digital setting. Additionally, real-time will established monitoring systems including Ultrasonic Test (UT) wall thickness monitoring, online Probes and remote monitoring unites (RMU) for cathodic protection (CP) provides a continuous trend of the necessary data from critical systems and locations using wireless communication and visual correlation with other corrosion activity parameters. Market available software programs facilitates an integrated and holistic approach to corrosion, inspection, and integrity management.
The discussion in this article demonstrates the reduction in cost/resources associated with full changeout from manual regularly monitor application against using digitalized remote and real time monitoring systems at susceptible locations.
The approach used represents a corner stone in the integration and optimization of corrosion management and RBI systems. This is supported by a clear timeline for required corrective actions based on data provided by the real-time monitoring, which is the key element in decision making and successful planning. This will also lead to decrease in the time required and resources involved in the CM and inspection activities, while fulfilling integrity assurance, maintaining ease of installation and future expansion.
This article presents how the digitalization of integrated CM and RBI modules along with real time monitoring are exploited to enable proactive decision-making using data that is frequent and accurate, establish a transparent and standardized reporting and communication process, and enhance management engagement and modification for integrity investment, along the way, using wireless UT installation, online corrosion monitoring and RMU for cathodic protection are cost-effective, dependable and ready for expansion.

Abstract
The rising cost of corrosion is alarming especially in ageing oil and gas production facilities. This situation is necessitated majorly by absence of corrosion management framework (CMF) which is a blueprint for identification and mitigation of common threats associated with corrosion in production assets. This paper explores the gains, challenges and improvement areas arising from development and implementation of robust corrosion management framework in fifty (50) oil and gas facilities.
The CMF was developed and implemented using threat identification, barrier design and barrier maintenance philosophy. The result of the CMF implementation revealed that most of these facilities are laced with unmitigated corrosion threats which predisposes the assets to hydrocarbon leaks. The results also provide insight as per the status of the pressure equipment, information for development of risk-based inspection plan and continuous improvement of corrosion management system. Some of the challenges encountered in effective CMF implementation for these facilities includes incompleteness of inspection data, unavailability of design data, absence of leadership commitment, competence gap and cost. This study has shown that CMF implementation is very critical in demonstrating sustainable asset integrity management and return on investment (ROI). However, to deepen the gains of CMF implementation in asset integrity management, there is need to have a well-defined roles and responsibilities, clear leadership commitment, visible corrosion management policy, digitalization of corrosion and inspection data acquisition, as well as competence development.

AbstractThe Yingxiongling structural belt is located in the south of the world's highest-altitude petroliferous basin, Qaidam Basin. The complete understanding and interpretation for the entire survey is becoming significantly more important for exploration well deployment. Survey merging has become urgent given the rising demand for further exploration and production in the area. In this paper, we have merged five blocks in the northwest into one. Dynamic warping plays a key role for post-migration data merge. With proper application of this technology and sophisticated model editing, we can minimize the time differences between different blocks. Finally, we provided a good subsurface seismic image for the further exploration evaluation of the Yingxiongling structural belt.

AbstractProgressing Cavity Pump (PCP) is a well-known artificial lift mode which is widely used for dewatering of coal bed methane (CBM) wells because it has good sand & gas handling capacity and better performance in deviated well in comparison to other rod pumps. However, compatibility of elastomer in downhole condition is always a challenging task for PCP operation. In this study, failure analysis of PCP well # A from ONGC field has been done in detail and suggest suitable remedial measures for multiple challenges.In well # A, high torque was observed during dewatering and after that sucker rod unscrewed. During work over it was observed that rotor got stuck up in the stator due to damage of elastomer. Based on reservoir study, it was found that unexpected gas breakthrough occurred from upper coal seam. Pump was placed above the upper coal seam therefore gas directly entered at the pump intake and elastomer got damaged. Another issue was high rod-tubing contact load due to highly deviated profile of the well. One guide per rod configuration was adopted for this well which is not enough to protect rod and tubing where maximum contact load simulated in standard software. The depth of failure of sucker rod is exactly matching with the depth of the maximum rod-tubing contact load.Based on two main challenges- high rod-tubing contact load & gas interference, different approaches have given in this study for safe pump operation keeping in view the field constraints.For high rod-tubing contact load, conclusions are drawn in this study with respect to important parameters causing significant effect. Suitable type and accurate configuration of rod guides are also suggested in this study.For gas interference problem, natural gas anchoring, tail pipe and use of different types of gas anchors have been compared and discussed to mitigate challenges in view of solid fines. Suitable elastomer type is also suggested depending on the well parameters.In case of multiple and complex problems observed in the well, this study gives novel idea to increase mean time between failure (MTBF) of PCP for dewatering of CBM wells in a relatively simple and effective manner.

Abstract
Cost and operation effective selection of drilling Bits to drill the HPHT Wells sections in Block-09 field in one run with optimum parameters.
Improvement in drilling performance leading to reduction in drilling time and costs without compromising the deliverability of well, is the primary objective of drilling engineers. Some of the major challenges faced by drilling engineers are drilling of hard and abrasive formations and selection of durable bits lasting for long while drilling each hole section. Traditionally in this part of south Iraq multiple Tricones and PDC bits were used for each section resulting in long tripping and drilling time. With recent advancement in drilling bits designs and careful and systematic approach for bits selection, these issues have been addressed and tremendous time and cost benefits have been realized.
This paper will provide insight into the drilling bits performance for HPHT Wells which have been used in Block-09 field and optimization of bits design to drill and tackle the issues faced in each section with achievement of one bit per section successfully. Dull grading comparison of the bits with offsets wells will be discussed. The optimum bits are then selected by performing a more through response- by-response comparison and how this comparison has been used for next bits selection and outcome of this selection will be presented, in addition the latest technology in bits industry has been benchmarked.
The paper will also review the formation types drilled in this block of south Iraq and will help to understand drilled formations and bits design relationship for drilling problematic zones especially sections containing Chert, high strength rocks, anhydrates, Asphaltene and argillaceous Limestone.
This paper will discuss the technical challenges which results in major borehole limiters, the engineering design and the Realtime practices that have been developed, as well as the field results.
This paper presents the accomplishment, experience and lessons learned related drilling in block-9 field south Iraq area where reduction in drilling time from 141 days to around 63 days is an outstanding outcome of "Pushing the Limits" concept and achieving one bit, one section target.

AbstractControlling unwanted water production is the key for the oil and gas industry. Consequently, water shutoff (WSO) fluids were introduced to favorably plug high permeability water zones or fractures and thereby reducing the water cut. Polymer gels have been utilized extensively to minimize undesired water production, especially from oil producers. Herein we present the study of gelation kinetics of an organically crosslinked polymer (OCP) gel with an adsorption system from intermediate to high reservoir temperatures.In this study, we utilized a cost-effective and environmentally acceptable fluid system. The fluid consists of polymer gel and adsorption constituents for carbonate formations. The system can be pumped downhole to the targeted zones as a single-phase solution with low initial viscosity. A systematic evaluation of the polymer gel for WSO applications is conducted at varied reservoir conditions. This includes a thorough examination of fluid properties at surface conditions before gelation starts, at which the system is referred to as gellant. Furthermore, we studied the properties during and after gelation kicks off at a wide range of temperatures. The emphasis of the experimental investigation was on the kinetics of OCP gelation through performing several rheology experiments at various crosslinker concentrations.The analysis revealed that the viscosity of the gellant at standard conditions was less than 20 cP; thereby, this contributes positively to having smooth surface mixing and pumping requirements for field testing. Based on reservoir temperature and cooling effect, the gelation time can be optimized by altering crosslinker concentrations. At fixed temperatures and varied crosslinker ratios, the gelation time exhibited a linear relationship with crosslinker concentrations. Additionally, the gelation time against temperature experienced an exponential behavior with reversible proportionality. By plotting the acquired data from massive rheological tests, we managed to attain precise correlations of gelation time for each OCP formulation. The gel prevailed in a high thermal stability fluid system to be gelled at a temperature of more than 250°F. Based on the presented lab observations, we concluded that this polymer gel system is expected to be trial tested in the field as WSO fluid for carbonate rocks.The OCP gel is a promising technology to mitigate excess water production from oil producers. Since the system has a low initial viscosity, it can be injected naturally in porous media. The presented work offers an insightful polymer gel system as a WSO fluid designed for treating carbonate rocks.

Abstract
A high-profile and major contributor exploratory well was at the verge of being a work-over candidate due to badly stuck coil tubing (CT) inside wellbore during routine well intervention operations. The situation got even worst when pin hole was established in CT string inside wellbore. The conventional and primary mechanism to release such CT is to operate hydraulic disconnect, which is an integral part of bottomhole motorhead assembly (MHA), by means of applying desired differential hydraulic pressure however, presence of pin hole restricted the desired differential pressure to communicate at motorhead assembly and to operate it. This work highlighted the importance of "back to the basics" phrase when conventional operating procedures failed to be executed and hence termed as "out of the box solution for coiled tubing retrieval". The method proposed in this work can be used by oil and gas professionals as the last resort to retrieve stuck coil tubing with complications like pin hole and failed hydraulic activation mechanism which will certainly avoid major cost exposure and operations complexities associated with rig assisted work-over.
In order to activate the hydraulic disconnect inside motorhead assembly of stuck coil tubing, depth of point of communication was estimated, inside volume of coiled tubing upto point of communication was calculated, additional pressure requirement to operate motorhead assembly was identified and heavy mud was pumped at a very slow rate in order to create hydraulic imbalance across coil tubing. Additional pressure due to hydraulic imbalance across coiled tubing was not sufficient to operate motorhead assembly therefore once the heavy mud reached point of communication; by calculation; high pressure pumping was performed in order to give high pressure pulses to motorhead assembly with a hope to activate and release it. All the theoretical calculations and planning based on above went as per plan and coiled tubing was successfully released.
The proposed principle of stuck Coil Tubing retrieval is new to oil industry as no literature has been found related to it. It not only saved a high profile well from expensive work-over operation but also the reputation of the exploration and production and service companies involved.
The novel approach presented in this paper is inherited from the concepts of fluid mechanics and has been successfully implemented. This methodology has all the merit to be included in the International Well Control Forum (IWCF) as the well control methodology for the stuck coil tubing with pinhole deeper into the well.

AbstractSurfactants are widely employed in chemical enhanced oil recovery (cEOR) technique. The economics of a cEOR project is directly impacted by the amount of surfactant loss caused by adsorption on a rock. Therefore, surfactant adsorption reduction is imperative. Both static and dynamic adsorption experiments were conducted to test the adsorption reduction of a novel Gemini surfactant on Indiana limestone. This novel surfactant is tolerant to high-salinity and high-temperature environments.Low salinity water was made by diluting sea water ten times. The salinity of Low salinity water was 6771 ppm. Rock characterization was performed first using XRD. Static adsorption tests were run using a crushed rock sample. Whereas core flood experiments were conducted to determine the dynamic adsorption behavior. High-performance liquid chromatography integrated with an evaporative light scattering detector was employed to calculate the unknown concentration of the surfactant.The effect of both high and low salinity water along with Gemini surfactant was investigated on the static adsorption of Gemini surfactant on Indiana limestone. It was shown that high salinity conditions result in the adsorption reduction in comparison with Gemini surfactant in deionized water. However, the use of low salinity water in the aqueous solution of Gemini surfactant further results in reducing surfactant adsorption. Dynamic adsorption test on Indiana limestone was found consistent with static tests. The ultimate reduced adsorption value of Gemini surfactant on Indiana limestone was found to be 0.11 mg/g-rock using low salinity conditions in dynamic experiments. Such low value lies under the economic limit, making a chemical EOR process efficient and economical. The novelty of this work is the use of low-salinity water in reducing the adsorption of a Gemini surfactant on Indiana limestone. The use of such a technique helps industrialists and researchers in designing an efficient and economical chemical EOR process.

AbstractWater flooding is an established method of secondary recovery to increase oil production in conventional reservoirs. Analytical models such as capacitance resistance models (CRM) have been used to understand the connectivity between injectors and producers to drive optimization. However, these methods are not applicable to waterflood fields at the initial stage of life with limited data (less than 2 years of injection history). In this work, a novel approach is presented that combines analytics and machine learning to process data and hence quantify connectivity for optimization strategies.A combination of statistical (cross-correlation, mutual information) and machine learning (linear regression, random forest) methods are used to understand the relationship between measured injection and production data from wells. This workflow is first validated using synthetic simulation data with known reservoir heterogeneities as well as known connectivity between wells. Each of the four methods is validated by comparing the result with the CRM results, and it was found that each method provides specific insights and has its associated limitations making it necessary to combine these results for a successful interpretation of connectivity.The proposed workflow is applied to a complex offshore Caspian Sea field with 49 production wells and 8 injection wells. It was observed that implementing the diffusivity filter in the models while being computationally expensive, offers additional insights into the transmissibility between injector producer pairs. The machine learning approach addresses injection time delay through feature engineering, and applying a diffusive filter determines effective injection rates as a function of dissipation through the reservoir. Hence, the combined interpretation of connectivity from the different methods resulted in a better understanding of the field. The presented approach can be extended to similar waterflood systems helping companies realize the benefits of digitization, in not just accessing data, but also using data through such novel workflows that can help evaluate and continuously optimize injection processes.
