The drilling and completion campaign scope included planned gas-injector wells that required a breaker application for matrix injection. A reversible nonaqueous reservoir drill-in fluid (RDIF) system using a calcium bromide brine as the internal phase and formulated at a 50/50 oil/water ratio (OWR) was selected. The complete paper discusses the results of extensive laboratory tests for the selection, customization of both the RDIF and the delayed breaker, and the field performance of the two fluids. 5 Journal of Petroleum Technology ARTICULO 194657 194657 0 0 0 0 262376 BAAB BAAB 2026-03-06 200067038 0 200067038 2026-03-06 00:39:34 2026-03-06 ARTICULO
