Neil Ritson, LGO’s Chief Executive, commented: “This is the first time that such extensive testing has been undertaken on C-sand wells in the Goudron Field and the process has yielded a great deal of very valuable information for the future development of the field.”
LGO Energy has told DirectorsTalk about its operations at Drilling Pad 4 in the Goudron Field in Trinidad. A total of 506 feet of C-sand pay was perforated across the three wells and all three wells have produced oil to surface. Wells GY-672, 673 and 674 were tested in reverse order. The tests on GY-672 are continuing whilst the preliminary results of tests on GY-673 are being used to determine how best to balance production and reservoir management. The tests on GY-674 have been completed, and production will commence once surface facilities are in place.
The production testing carried out on well GY-674 has provided the anticipated engineering information. The well delivered a natural flow rate of approximately 240 barrels oil per day (“bopd”) when flowed with a 8/32-inch choke. An absolute open-hole flow rate of approximately 500 bopd has been estimated from the test results.
Once the GY-673 data analysis has been completed, we expect that production from that well will be optimized by means of downhole pumping. Initial results from the tests at GY-672 suggest that a downhole pump may also be the most appropriate production approach on that well.
Well testing is an integral part of longer term development planning providing vital data on factors such as flow capacity, reservoir deliverability, permeability and completion efficiency. The data obtained will also be valuable in planning for the expected enhanced oil recovery project.
In other news LGO also said today that the currently drilling C-sand well, GY-676, is drilling ahead in the 8 ½” section of the well at a depth of 2775ft. Formations that have been encountered in the well so far have come in on prognosis.
