Green Canyon development wells are perforated and tested using the IMPULSE* testing method before completion or recompletion. This method allows a controlled underbalance stimulation of unconsolidated formations so that an initial reservoir pressure and reservoir data can be obtained. A pressure pulse controlled drill stem test (DST) system is used to carry out these well testing operations.
This new DST control concept overcomes some of the limitations of conventional DST tools; equipment reliability is increased in difficult well conditions. This new system has improved the efficiency and safety of well testing in this area.
