Petroleum Africa: La-107 Sees First Production

100

Victoria Oil & Gas (VOG), through its Cameroonian subsidiary, Gaz du Cameroun (GDC) saw success with its flow tests and first production gas from the Logbaba La-107 well. The well reached target depth of 3,180meters, the base of the Logbaba Formation, encountering a total of 58 meters of net gas bearing sands in the Upper and Lower Logbaba Formations.

Following the installation of the production completion and production tree, La-107 was perforated and flow tested to a maximum rate of 54 Mmscf/d. The multi-rate test results indicate that the well has an AOF potential of 146Mmscf/d; this is considerably better than expected and compares very well to La-105 which had an initial AOF of 89Mmscf/d.

After conducting clean up and flow testing operations the well was connected to the Logbaba Gas Processing Plant and first gas flowed to the processing plant for sales on September 22.

The drilling rig was released from La-107 on September 3 and skidded to La-108 to resume drilling operations on that well. Following procedures to re-enter the well, side-track operations commenced on La-108 on September 10. The side-track is planned to re-drill the 8½” hole section which was previously lost, where more than 100meters of net gas-bearing sands were encountered at intervals between the top of the Logbaba Formation at 2,107meters MD and 2,760meters MD.

The combined testing and drilling operations on both La-107 and La-108 were planned and conducted under industry recognized Simultaneous Operations Procedures (SIMOPs) to ensure a safe, efficient and successful outcome of a complex operation.
