A Caribbean-focused explorer has completed production tests on the Goudron Field in Trinidad which has resulted in an open-hole flow rate of 540 barrels of oil per day in one of its wells.
Leni Gas and Oil was given the go-ahead to begin drilling 30 new wells at its Gourdon oil field for the first time in 30 years in January.
The company made the announcement regarding well GY-667 after it underwent a series of initial production tests.
After perforating a 44ft interval in the Lower Cruse Sandstones, there was a calculated result of 540 barrels of oil per day.
It exceeded initial estimates by the company of 60 barrels of oil per day.
The well is presently producing 40 degree API gravity water-free oil at a rate of 142 barrels of oil per day through a 7/32-inch choke with a well-head flowing pressure of 420 psi.
Higher rates of up to 220 barrels of oil per day have been successfully tested, however, temporary field-wide production constraints are in place until the additional sales capacity is on-stream in the next week.
Neil Ritson, chief executive of Leni Gas and Oil, said: “The results from GY-667, the company’s first completion in the Lower Cruse reservoir, have far exceeded our initial estimates of 60 barrels of oil per day.
“We have yet to confidently locate the thickest zone of Lower Cruse Sandstones and therefore we are excited that a relatively thin interval is producing so prolifically.
“This is very encouraging for further potential in the Lower Cruse within the field.”
The shallower primary Gros Morne reservoir in GY-667, with 219 feet of net oil pay, will be completed for production at a later date.
In addition to well GY-667, the company also confirmed initial production tests have been conducted on GY-666 and GY-668.
These have resulted in calculated open-hole flow rates of 300 and 330 barrels of oil per day respectively.
Further clean-up work is required on these two wells to optimize flow rates.
