Brine displacements were one of several areas of focus in a continuousprocess to optimize completion methodology in Amerada Hess's Ceiba projectwells located in deepwater offshore Equatorial Guinea. The time between whenthe cleaning string is made up and when it is laid down after displacement andfiltration operations are completed can exceed two days and cost $500,000. Itis imperative that wellbore cleaning operations are performed efficiently andcorrectly the first time. Amerada Hess and its brine suppliers working togetherin a joint task force have taken specific steps to minimize the time requiredfor displacement and filtration operations.
