Eland Oil & Gas, through its JV subsidiary, Elcrest Exploration and Production Nigeria, completed the drilling phase of the Gbetiokun-4 development well.
The OES Teamwork rig has successfully completed drilling operations on the Gbetiokun-4 well; the first well to be drilled on the Gbetiokun field following approval of the Field Development Plan (FDP) on July 3 by Nigeria’s Department of Petroleum Resources.
Analysis of log data indicates that the well has exceeded pre-drill expectations, encountering high-quality oil-bearing reservoirs close to prognosed depths. In all, approximately 345 net ft true vertical depth (TVD) of oil-bearing sand was encountered across multiple reservoirs. During the drilling phase, a 60 ft core was cut in the E5000 reservoir, with 100% recovery, which will facilitate further detailed reservoir characterization, reservoir management and optimize life of field.
The well will now be completed as a dual oil producer on the E5000 and E7000 reservoirs, which have total net pay thicknesses of approximately 63 ft and 49 ft TVD respectively. The secondary target reservoir, E3000, which encountered 48 feet TVD of net pay will also be perforated and placed behind a sliding sleeve ready for production at a later time.
Completion of the Gbetiokun-4 well is expected at the end of September with production commencing through the recently commissioned EPF immediately thereafter. The EPF is already online and handling production from previous wells Gbetiokun-1 and Gbetiokun-3. Gbetiokun-4 should increase throughput from the current 11-12,000 bpd (gross) to approximately 16-17,000 bpd (gross).
Following completion of the Gbetiokun-4 well the OES Teamwork rig will commence operations on the Gbetiokun-5 development well which is scheduled to provide additional drainage points on the D9000 and E2000 reservoir zones.
