In 2022, a multi-fractured horizontal well was completed with indeterminate results in terms of productivity but paved the route to the design of a pilot...

... for quantitative evaluation. In this work, we look at the feasibility and capability in high-risk environments using advanced LWD technology, with a focus on high-definition imager to characterize fracture network. Drilling bottom-hole-assembly (BHA) was uniquely designed with fit-for-purpose technology...

... characterization methods are essential to identify sweet zones in shale oil systems. The source-reservoir configuration is a critical factor in shale oil reservoir evaluation. This study introduces an integrated approach combining 2D nuclear magnetic resonance (NMR) T1-T2 logging, induced gamma-ray spectroscopy...

... Abstract Evaluating potential investments under uncertainty comprises one of the most critical tasks in opportunity evaluation. While price, capex, and resource variability have a significant impact on investment performance, the effect of management judgment can also materially enhance value...

... implemented across 40 leases operated by nine companies. The success of these projects depends heavily on a clear understanding of production profiles and PVT (pressure-volume-temperature) phase behavior (Grinestaff et al., 2020). This study developed a robust workflow to evaluate production profiles before...
