Lost circulation has become one of the important problems restricting speed and efficiency oil gas drilling production. To address severe fluid losses in high-temperature fractured formations during deep/ultra-deep well drilling, this study developed a high-strength gelled resin gel plugging system through optimized matrix selection, latent curing agent, flow regulator, filling material, etc. Comparative analysis five thermosetting resins revealed urea-formaldehyde as optimal matrix,...
The poor lubrication performance of water-based drilling mud hinders its application in the process extended, reach horizontal wells. To overcome this shortcoming, polyaspartate (PA) and poly(ethylene glycol) (PEG) were used to improve mud. conventional performances, performance, micro-image antiwear steel balls modified analyzed. results show that coefficient friction (COF) mixed with 10% PA 5% PEG was lowest, reaching 0.094, reduction rate COF 63.1%, cake stuck factor also lowest. addition...
The authors present a case study of using semi-quantitative oil fingerprinting technology to correctly back allocate production individual sand layer in commingled well. A large number samples were collected over time and analyzed by gas chromatography (GC) for their fingerprints. results showed that the allocation single two-layer well hydrocarbon concentrations liner relationship. However, GC fingerprint parameters curvilinear was suitable well, three-layer with larger differences among each layer.
