SPE Journal, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 18

Published: Feb. 1, 2025

Summary Field development optimization in the oil and gas industry is crucial for balancing economic viability environmental sustainability amidst complex challenges advancing technologies. Infrastructure-led exploration aims to optimally use existing infrastructure, ensuring significant cost savings benefits. In this paper, we present a method designed optimize field expansion industry. The workflow utilizes brownfield infrastructures evaluates potential of neighboring brownfields or other opportunities maximize supplementary value enhance decision-making processes. integrates key data on production flow rates, terms capital expenditure (CAPEX), net (NPV) from projects performs detailed capacity assessment while accounting varied project timelines. This allows selection bundle optimal that portfolio within predefined constraints. Test cases demonstrate workflow’s capability identify feasible economically viable opportunities, illustrating its significantly resource management value. proposed provides comprehensive framework optimizing oil- gasfield by integrating analysis, case-dependent customization, reporting. flexibility enables tailored analysis specific needs, enhancing operational efficiency. innovative algorithms presented paper address critical timely challenges, encompassing both profitability projects.

Hydrogen-Battery Hybrid Energy System on Repurposed Offshore Platforms for Efficient Clean-Energy Transition

Offshore Technology Conference, Journal Year: 2025, Volume and Issue: unknown

Published: April 28, 2025

Abstract Due to the rising global energy demand and enhanced awareness of environmental impact fossil fuels, Gulf America (formerly called Mexico), traditionally known for oil extraction, offers a distinct chance repurpose existing offshore infrastructure. With depletion reserves, it is feasible adapt previously utilized floating platforms extraction generate renewable energy, specifically through wind-generated power hydrogen production. This adaptation seeks promote transport system that more ecologically friendly in future. Offshore wind turbines will serve as principal source, while battery storage production complement overall performance fulfill fuel electricity sustainable generation. The divided into two cases, each evaluated cost, performance, feasibility, with focus on minimizing both Levelized Cost Energy (LCOE) Hydrogen (LCOH). first case examines integration Excess generated by directed toward via electrolysis. produced can be used vehicles or transported shore pipelines. second investigates technology combines storage. In Case 1, Particle Swarm Optimization (PSO) optimizes constraints efficiency electrolyzer hydrogen, which lowers OPEX $9.60 million keeping CAPEX at $300.00 million. Thus, reaches an annual 4.72 kg, giving rise LCOH $7.49/kg yearly profit $9.27 Grey Wolf (GWO), also performing optimization efficiency, obtained 4.57 kg hydrogen-an equalling $7.73/kg $8.70 per year. 2, GWO cycles charge discharge so prolong life cut expenses. $225.00 produces 14.76 MWh LCOE $41.50/MWh, making $4.17 balanced reasonable cost-performance ratio compared PSO (which gives $41.24/MWh profits $3.98 million). implementation comprehensive strategy results substantial reduction costs, improved dependable supply electric emphasizing benefits converting clean transition. study explores enable cost-effective repurposing O&G platforms. Both cases highlight economic technical feasibility transitioning systems, demonstrating cost reductions reliable supplies

Repurposing Offshore Infrastructure for Clean Energy (ROICE) vs. Decommissioning – Commercial Considerations

Offshore Technology Conference, Journal Year: 2025, Volume and Issue: unknown

Published: April 28, 2025

Abstract The Repurposing Offshore Infrastructure for Clean Energy (ROICE) Program, a collaboration of the energy industry and University Houston, proposes extending life up to 1,500 oil gas platforms in Outer Continental Shelf Gulf Mexico, USA. Rather than decommissioning or converting them underwater reefs at end their production phase, could be transformed 10–20+ years renewable development, such as green hydrogen carbon dioxide injection storage, resulting significant economic, environmental, social benefits. ROICE has already published papers on technical regulatory considerations repurposing projects. This paper focuses commercial needed ensure projects are economically viable sustainable all involved. There potentially many entities that can come together progress project, including asset owners, operators, investors, developers, contractors, manufacturers, regulators. looks possible combinations these project team various agreements will mutually successful outcome. adapting existing templates suit, transfer (ATA), purchase (APA) joint purchasing (JOA).
