Shear logs, also known as shear velocity are used for various types of seismic analysis, such determining the relationship between amplitude variation with offset (AVO) and interpreting multiple data. This log is an important tool analyzing properties rocks data to identify potential areas oil gas reserves. However, these logs often not collected due cost constraints or poor borehole conditions possibly leading quality, though there approaches in practice estimating wave velocity. In this study, a detailed review recent advances techniques measure (S-wave) carried out. These include direct indirect measurement, determination empirical relationships S-wave other parameters, machine learning, rock physics models. Therefore, study creates collection employed techniques, enhancing existing knowledge significant topic offering progressive approach practical implementation field.

A parametric study on in-situ hydrogen production from hydrocarbon reservoirs – Effect of reservoir and well properties

International Journal of Hydrogen Energy, Journal Year: 2024, Volume and Issue: 80, P. 733 - 742

Published: July 17, 2024

Energy transition is a key driver to combat climate change and achieve zero carbon future. Sustainable cost-effective hydrogen production will provide valuable addition the renewable energy mix help minimize greenhouse gas emissions. This study investigates performance of in-situ (IHP) process, using full-field compositional model as precursor experimental validation The reservoir was simulated one geological unit with single point uniform porosity value 0.13 five-point connection type between cell computational cost. Twenty-one forming reactions were modelled based on fluid composition selected for this study. thermodynamic kinetic parameters obtained from published experiments due absence data specific reservoir. A total fifty-four simulation runs conducted CMG STARS software 5478 days cumulative produced each run recorded. Results generated then used build proxy Box-Behnken design experiment method Support Vector Machine RBF kernel. To ascertain accuracy models, analysis variance (ANOVA) variables. average absolute percentage error numerical calculated be 10.82%. Optimization performed genetic algorithm maximize produced. Based optimized model, influence porosity, permeability, well location, injection rate, pressure studied. Key results reveals that lower permeability reservoirs supports more yield, had negligible effect increase in oxygen rate corelated strongly until threshold beyond which yield decreased. framework developed could tool assess candidate production.

Techno-Economic Analysis of Hydrogen Generation in Hydrocarbon Reservoirs

SPE Journal, Journal Year: 2024, Volume and Issue: 29(10), P. 5752 - 5760

Published: Aug. 1, 2024

Summary To reduce carbon emissions and meet increasing energy demands, efforts are being made to seek clean such as hydrogen (or H2). Currently, the dominant method generate is steam methane reforming at a surface plant. It would be ideal extend this subsurface hydrocarbon reservoirs; separated from other generated gases via downhole hydrogen-selective membrane separator. By doing so, extracted wellhead, left in reservoir. The purpose of paper provide techno-economic analysis idea. compared with feedstock. selectivity (concentration) synthesis gas (syngas) amount per unit mass oil literature reviewed discussed. constraints generation conditions reservoirs effectiveness found that much less than input even reactor where reactants fully mixed for reactions. In reservoir, injected cannot mix in-situ gas, reactions may occur only near flood-front zone high temperature. As (such or oxygen) displaces ahead, produced hydrocarbons higher hydrogen. Separation presents challenges many aspects reality, permeability separation rate, work life (mechanical chemical stability), so on. Therefore, unless revolutionary technology breakthrough occurs, production reservoir not feasible.

Abstract The climate math is clear: carbon capture and storage (CCUS) an essential mitigation technology, without which achieving net‐zero emission targets will be virtually impossible. This requires periodic assessment continuous improvement of the technology from various perspectives. short review highlights current state CCUS deployment, recent achievements, associated challenges. project pipeline at all‐time high in terms both number facilities dioxide capacity. Currently, 47 operational projects have annual CO 2 capacity 50.5 Mt /year. total expected to reach 600 natural gas sector major contributor, accounting for more than 65% While significant progress made years, particularly North America Europe, deployment faces several challenges that are multifaceted, encompassing technical, economic, regulatory, social dimensions. Policymakers, industry leaders, investors, general public increasingly feeling urgency address change, accelerating many efforts, including leading regions globally. However, meet change targets, global investment must grow even faster this decade.
