An operator sought to improve oil production from a development field offshore Gabon. After laboratory tests, M-I SWACO proposed using the VERSA-OUT water-based filtercake breaker system in the open hole for filtercake treatment of the VERSAPRO invert-emulsion reservoir drill-in fluid system. When the well was placed on production after treatment, oil production exceeded the operator’s highest expectations by more than 15%.
