Published: February 2025

Achieving global net-zero emissions by mid-century necessitates a variety of climate mitigation technologies, including carbon capture, utilization, and storage (CCUS) or carbon capture and storage (CCS). According to analyses by the Intergovernmental Panel on Climate Change (IPCC), the International Energy Agency (IEA) and other sources, CCS will be required as a part of a suite of mitigation strategies in order to meet emissions targets (Global CCS institute, 2023). This will require a significant expansion of CCS by mid-century, despite numerous challenges throughout its value chain. Identifying and developing suitable storage spaces and capacities are crucial, and dedicated programs are essential to evaluate and enhance these potential storage sites for CCS.

CCUS can be categorized into three main types: CO2 enhanced oil recovery (EOR), pure CO2 storage in saline reservoirs, and storage in depleted reservoirs. In CO2 EOR, CO2 is utilized, recycled, and reused to boost hydrocarbon production. Conversely, storage of CO2 in deep saline reservoirs or depleted oil and gas fields is a permanent storage solution that will help achieve global net-zero. However, there are currently fewer commercial-scale projects focused on these types of storage compared to CO2 EOR projects (Rubin E. et al. 2018).

Advanced subsurface geological and reservoir engineering studies indicate that there is substantial CO2 storage capacity globally, particularly in subsurface saline reservoirs. According to the IEA's 2021 estimates, the total global storage capacity ranges from 8,000 Gt to 55,000 Gt, primarily in saline reservoirs based on geospatial data from NGO databases. However, the economic viability of CCS projects is uncertain due to the lack of specific subsurface data, such as production data and geological characteristics, in regions outside hydrocarbon areas and saline wet reservoirs. Additionally, the limited surface infrastructure in these regions exacerbates this issue. This lack of data leads to uncertainty in key factors such as tank capacity and injectability, which in turn contributes to economic uncertainty for CCS projects.

Generally, obstructions in the completion string are removed with chemical and mechanical means, depending on their nature. When the nature of obstruction is obscure, the rules of thumb, best practices, and lessons learned from the past are consulted. During the coil tubing milling operations to mill the cement and plug post workover, obstructions were encountered above the sand screens restricting the wellbore accessibility and restoring the production. Instead of another work-over, a resilient engineering approach spanning different steps was adopted to overcome the obstruction. The best practices and the lessons learned in reviving the well are the subject of discussion in this paper.

Numerous techniques were adopted during the intervention operation to identify and bypass the nature of damage present downhole to access the sand screen. CT cleanout runs were devised but remained inconclusive in overcoming the downhole obstructions. Therefore, wellbore diagnostic was performed using downhole camera, which increased the understanding of actual downhole challenges. Based on the wellbore diagnosis, certain best practices and lesson learned were applied in subsequent cleanout / milling operation that allowed access to the sand screens and enabled removal of detritus which was obstructing hydrocarbon flow from the sand screens. The downhole tools and fluid selection played pivotal role in increasing the effectiveness of applied best practices.

A combination of through tubing wellbore diagnosis, cleanout, and milling applied with best field practices restored access to the wellbore's total depth (TD), re-establishing the well's flowing potential. Wellbore diagnosis provided visuals to enable better understanding of the actual conditions unaccounted for in the initial intervention operations. The presence of scale, ID reduction and sluggish material in front of screens required a customized intervention approach. Accordingly, cleanout and milling runs were devised with contingencies to tackle any unforeseen circumstances.

Wellbore diagnosis, cleanout, and milling are not novel and are frequently deployed in well- intervention operations. Nevertheless, the result of two operations under the same conditions differ due to the technicalities involved. The application of best practices and lessons learned, when combined with wellbore diagnosis, played a key role in the success of this operation. This paper will highlight those tools and techniques to reach a wider audience and avoid similar issues. Moreover, areas of further improvement and novel means of achieving "more with less" shall also be discussed for continuous improvement of intervention operations.

Published: February 2025

Fractured reservoir is one of the critical reservoir types, and the accurate characterization and prediction of fractures are essential for the high-efficiency development of oil fields. Due to the complexity and multiple solutions, fractures pose significant challenges to quantitative predictions. By integrating outcrop, seismic and core research methods, this paper analyze fracture characteristics such as length, strike and aperture, to determine the genesis, scale, and period of multi-scale fractures. Subsequently, we employ the finite element numerical simulation method to build a geomechanics model, which can be used to quantitatively simulate the aperture, density, and other parameters of fractures. Additionally, statistical methods are employed to provide a quantitative description of formation, fault, and fracture parameters. A multi-scale discrete fracture network model is then constructed using single-well fracture data, while considering multiple constraints such as geomechanics, curvature, and distance to fault. The geomechanics-based multi-scale fracture modeling method simulates fracture development under various conditions and constraints, considering fracture genesis from a comprehensive perspective. This approach allows for more systematic identification of fractures and more accurate predictions, leading to improve prediction accuracy. The method provides valuable guidance for well deployment, optimizing gas recovery rates, and enhancing recovery. It also serves as a basis for later engineering modifications, and has significant research implications for the gas development.

Published: February 2025

A practical solution to energy transition and the increasing demand for energy is underground hydrogen storage (UHS). The contribution of hydrogen (H2) as a clean energy source has proven to be an effective substitute for future use to meet the net-zero target and reduce anthropogenic greenhouse gas emissions. One of the most important factors affecting H2 displacement and storage capacity under geological circumstances is storage column height. The objective of this study is to underscore the importance of large-scale H2 storage and use reliable machine learning algorithms to evaluate and predict the H2 storage column height under varied thermophysical and salinity conditions.

In this study, the dataset of 540 datapoints for the evaluation and prediction of storage column height is generated, which involves three main parameters: density difference (Δρ), interfacial tension (IFT) and contact angle (θ). The correlation of contact angles against various reservoir depths is used and H2 storage column height is evaluated. Thermophysical conditions include pressures (0.1-20 MPa), temperatures (25-70°C), and salinities including deionized water, seawater and brines of 1 and 3 molar concentrations for various salts (NaCl, KCl, MgCl2, CaCl2, and Na2SO4) from our experimental data. The H2 storage column height (h) is predicted using three machine learning (ML) models, viz., random forest (RF), decision tree (DT) and gradient boosting (GB).

Statistical data analysis is performed to generate the distribution of dataset and correlation coefficient is calculated while feature importance is determined to identify the relationship of each input parameter with output parameter using Pearson, Spearman, and Kendall models. RF and GB, as demonstrated in this study, have shown promising results in providing accurate predictions while maintaining generalizability. Various error assessment metrics including MSE, RMSE, MAPE and R2 are utilized for the evaluation. Prediction of column height resulted in R2 values of 0.995 for training and 0.999 for testing with RF model. Whereas the GB model also resulted in superior performance with R2 values of 0.997 during the training phase and 0.995 during the testing phase. However, the DT model resulted in R2 values of 1 and 0.994 during the training and testing phases respectively. While MSE value of 0 is obtained for DT model which indicated overfitting.

The findings of this study suggest that data-driven ML models can be a powerful tool for accurately predicting the H2 storage column height and can be effectively used to determine the displacement of H2 and storage capacity, reducing the time and cost associated with determination using traditional methods. In addition, advanced ML algorithms can be explored in the future to overcome the challenges pertinent to the determination of storage column height.

Published: February 2025

Efficient utilization of unconventional resources hinges on the strategic deployment of wells across multiple pads on a large scale. However, the unique geomorphological constraints, along with considerations for the forest reserves and water source reserves in the Loess Plateau, pose limitations on the well pattern for Chang 7 shale oil in the Ordos Basin. To enhance the utilization of pad reserves, an innovative approach suggests the adoption of a fan-shaped well pattern.

Based on the study area, a high-precision 3D geological and geomechanical model was meticulously developed. This model enabled the exploration of the impact of various horizontal well trajectory directions on fracture propagation and productivity. The optimization demonstration of well placement within the pad fan-shaped area was carried out concurrently. Additionally, a comprehensive analysis was conducted by integrating field trial, enabling a thorough assessment of the differences in fracturing effects and productivity.

In contrast to conventional horizontal wells, productivity of oblique horizontal wells exhibits a decline as the deflection angle (the angle between the horizontal well trajectory and the minimum horizontal principal stress direction) increases. Taking into account the lateral length and conventional well spacing, the optimized fan-shaped well spacing is 150-200m at the heel and 700-750m at the toe. Fractures in oblique wells initially propagate along the vertical wellbore direction, gradually deflecting towards the maximum horizontal principal stress direction due to stress control. Despite the small stimulated reservoir volume (SRV) and delayed oil discovery associated with oblique wells, their notable characteristics include a high shut-in pressure, pronounced fracture complexity, and a more sufficient stimulation. Comparative analysis with actual production results reveals that the cumulative production of oblique wells is lower than that of conventional wells. However, the difference in production shrinks after the end of the flowback period, indicating corresponding development potential.

In this study, the irregular well pattern is demonstrated under the well pad limitation, and the field trial results are analyzed and evaluated, which provides guidance for similar development models.
A Diagnosis Method for Lost Circulation Based on Improved Symbolic Aggregate Approximation and Support Vector Machine

Published: February 2025

In the process of ultra-deepwater drilling, the safe density window is narrow, and there are issues with large temperature differences and alternating high and low temperatures, making wellbore pressure control challenging and highly prone to complex lost circulation incidents. To achieve safe and efficient drilling, accurate identification and timely monitoring of complex lost circulation incidents are essential. To address the current issues of insufficient real-time performance and accuracy in lost circulation monitoring for ultra-deepwater drilling, this paper proposes a multi-parameter lost circulation monitoring method based on support vector machine (SVM). Firstly, a transient hydraulic model for lost circulation in ultra-deepwater drilling was established to capture the variation patterns of wellbore flow parameters during loss incidents, thereby creating a standard model for lost circulation monitoring parameters. Then, by considering the average difference and slope characteristics of the time series of these parameters, an improvement was made to the classic symbolic aggregate approximation (SAX) method. This method was used to perform dimensionality reduction on real-time drilling data, calculating the similarity metric distance between the monitoring parameters and their corresponding standard model, thereby enhancing data processing efficiency. Finally, a multi-parameter lost circulation monitoring model based on Particle Swarm Optimization-Support Vector Machine (PSO-SVM) was constructed. This model uses the similarity metric distances of multiple monitoring parameters to comprehensively assess complex lost circulation conditions, thus improving the accuracy of lost circulation monitoring. A case study was conducted on a lost circulation well in the South China Sea, and the results demonstrated that this method effectively identifies complex lost circulation conditions with good real-time performance and accuracy, providing a new approach for monitoring complex lost circulation conditions in ultra-deepwater drilling.

PETRONAS completed well BA-42 on Field BS in offshore Malaysia by pushing to the limit and deviating from the "norm" in delivering cased hole gravel pack with 7″ Single Trip Multi Zone (STMZ) system. This 7″ STMZ installation represents the first ever successful installation of the technology in high angle 5 zones well with maximum inclination of 85 degrees with gravel pack treatment up to Extension Pack pumping technique.

The STMZ system has been successfully installed in a high angle 5 zones well, offshore Malaysia, eliminating the need for multiple perforation, well bore clean up, and conventional stack pack trips, reducing operation time and risk exposure. However, the BA-42 well brings an additional challenge and risk due to the requirement to complete and treat 5 zones across the maximum inclination of 85 degrees. Intensive discussions and simulations have been made to ensure the operation runs smoothly, and major changes have been made to the design of the positioning tool to incorporate lessons learned from previous jobs.

The installation of 7″ STMZ across 5 zones with a maximum inclination of 85 degrees was successful. All tangibles and service tools were run in the hole and landed in the sump packer. The top packer and isolation packers were set, and a good annular pressure test against the top packer was obtained. The FCS / SSD was opened using the Proprietary Z2-Open Only Shifter in the service tool string, and the opened sleeve was tested to 500 psi through the annulus to check the leak-off and ensure the sleeve was in the open position. The service tool was then moved to open the MCS using Proprietary Z2-Open Only Shifter. The operation continued as per the pumping program, which included reverse friction test, circulation test, injectivity and breakdown test, matrix acidizing, re-injectivity test, circulation test, step rate test, and screen out drill. The job type for each zone varied between gravel pack up to extension pack, where the pumping treatments performed using viscoelastic surfactant (VES) as gravel carrier fluid. The upper completion string was then run in the hole as per the tally and landed successfully. All sleeves were opened via electric wireline and tractor for unloading and production, and since then, no sand has been produced.

STMZ system has always been synonymous with being complex. However, the success of 1st in the world, 7″ STMZ in 85-degree inclination with 5 zones has proven that with excellent planning, proper risk assessment and flawless communication, anything is possible. This success has also highlighted the capability of STMZ technology to significantly reduce the time required for multiple zone sand control installation and HSE exposure, which in turn makes marginal wells profitable and economical.
Net Zero CO2 Emission Utilizing Energy from Gas Hydrates - Carbon Neutral Methane Production with CO2 Storage and Conversion to Hydrogen
Authors: Graue Arne , Ersland Geir
Published: February 2025

While the world needs more energy, there is a growing societal demand to cut emissions. IEA estimates that 70% of energy consumption in 2035 will still be from fossil fuels. Due to the concern for global warming, new energy resources need to be cleaner, although the dependency on fossil fuels will continue. This paper presents a net-zero emission technology to meet this challenge by methane production from natural gas hydrates with concomitant CO2 storage. To demonstrate the technology for industry and investors, laboratory results have been upscaled to a field pilot test performed in Alaska. Utilizing CO2 as a commodity to produce methane from hydrates, in a carbon neutral exchange technology, has provided a disruptive new CCUS technology. This technology may reduce CO2 emissions by 50% when substituting methane for coal in power plants. When producing hydrogen from the produced methane, hydrogen is enabled as an energy carrier with no CO2 emissions, even when utilizing energy from fossil fuels.

Introduction. The role and the importance of the region in the system of economic entities is increasing, thus, it is relevant to shift the interest alignment to the territorial level. At the same time, the region has a large number of actors engaged in activities addressing socio-economic problems through the use of various mechanisms, tools and technologies, and one of the most promising of them is the intersectoral social partnership. Since this mechanism is currently underway, it has not yet fitted in the regional development. In this regard, the purpose of the current research is to determine the role of intersectoral social partnership in the region. The scientific novelty of this paler is that the authors used systems approach to determine the role of intersectoral social partnership in the region based on the correlation of actors involved in intersectoral social partnership with the components of the regional system. Methods.The social partnership should be regarded from the position of a systems approach, since it is most relevant to the goals and objectives of the research. Results.

Introduction. One of the most important areas of a company’s financial policy is the development of investment management and investment policy. The need for companies to form the investment policy is driven by two factors: first, the duration of the investment cycle can be 5-10 years (depending on the field and the scale of production); second, the items created in the framework of investment activities cannot often be converted into the original monetary form.
