Study of Lost Circulation Protection and Control Drilling Fluid for Induced Cracks

2018
Serious mud losses happened at Huaqing Oil Field due to the induced fractures. The current bridging plug agent is poor adaptable to the fracture and pore size. The bridging material, polymeric adsorbent materials and filler materials and particle size distribution were optimized.

Effectively Controlling Gas Migration When Lost Circulation Is Encountered in South Texas

All Days, 2005
Abstract South Texas is predominantly known for high pressure and high temperature formations resulting in the primary production of gas. As operating companies produce from shallower sands, deeper sands are the new targets.

Kick with Lost Circulation Simulator, a Tool for Design of Complex Well Control Situations

Proceedings of SPE Asia Pacific Oil and Gas Conference and Exhibition, 1998
Abstract Being able to simulate drilling problems when operating within narrow margins between formation pressure gradients and fracture pressure gradients can cause great savings through improved planning. This is especially the case for HPHT and Deep Water wells. Lost circulation (i.e.

Controlled Retardation of Sorel Cement Using Sodium Salicylate for Lost Circulation Control in Naturally Fractured Reservoirs

SPE Journal
Summary Sorel cement has emerged as an effective solution for controlling severe leakage during drilling in fractured formations. However, it can thicken prematurely under high-temperature and high-pressure (HTHP) conditions in the wellbore, leading to operational risks, such as pipe sticking and pressure trapping.
