Stringent drill-in fluid design results in prolific deepwater horizontal well ///

This article overviews the drill-in and completion of BP-operated offshore development well Marlin A-4 in the Eastern Gulf of Mexico. Objectives of the well are outlined. Design and selection of a drill-in fluid to meet selected inhibition, toxicity, rheology and filter-cake cleanup is described, which led to use of TETRA Technologies’ proprietary, brine-based PayZone drilling fluid. Drilling and completion operations are described, which led to a successful gravel pack and sustained production of 87 MMscfd gas and 9,700 bpd condensate.
