.... The use of a selected viscoelastic water-based drilling fluid system, with a thixotropic behaviour, and appropriate lost circulation procedures drastically reduced downhole loss rates and improved overall drilling performance. Laboratory testing conducted during the planning and execution phases...

The Paper as presented at OMC 2017 has not been reviewed by the Programme Committee. ABSTRACT Drill-in fluid systems...

... of fluid additives have been field tested in the CV horizontal wells with the goal of decreasing frictional forces. Examples include refined oil, sulfonated asphalts, graphite, and fine beads. All of these additions yield varying, inconsistent results. Using a newly developed high-performance fluid system...

The paper describes the development of the new fluid system designed for such uHTHP environments, highlighting the chemical differences and comparing the test data of the system with more conventional HTHP invert emulsion fluids. Data is presented showing...
