Research on Calculation Methods for Flow Distribution and Pressure Loss of Reaming-While-Drilling (RWD) Tools

As global oil and gas exploration advances into deep reservoirs, reaming-while-drilling (RWD) tools (hereinafter referred to as the reamer) are widely used to enlarge wellbores for unconventional well structures, prevent stuck pipe caused by formation shrinkage, and improve cemen...

Three-Dimensional Identification of In Situ and Migrated Organic Matter in Shale Based on Micro-CT

Accurate differentiation of in situ organic matter (IOM) from migrated organic matter (MOM) and their three-dimensional characterization are fundamental for understanding hydrocarbon generation, migration, and accumulation in shale reservoirs. However, conventional micro-computed...
