Most of the wells in the Dzheitune (Lam) field in the Caspian Sea were completed with dual tubing. Depletion in reservoir pressure caused formation failure in the A sand reservoir, and wells producing from this formation began to produce sand. Field examples presented in the complete paper describe principles of data acquisition with a sand-detection tool when run in combination with a production logging string and results of logging in slightly deviated wells completed with sand screens. Comparison of multiphase-inflow profiles with sources of sand production showed that most sand was produced through eroded intervals in the sand screens.
Introduction
Most Lam wells were completed with 9.625-in.
