Acquiring Remaining Gas Saturations in a Pilot Hole Drilled from a very Extended Reach Drilling Well in a Mature Field

An out-stepping appraisal pilot hole was drilled away from centrally clustered producing wells in a carbonate field operated by Sarawak Shell Berhad. This presentation outlines the planning involved prior to drilling the well which had the rare opportunity to drill below the original gas-water contact in a producing field. Part of the appraisal content of the pilot hole was to acquire residual gas saturations.
