Serinus Energy Inc. reported that the Winstar-12bis well (WIN-12bis) was tied into the flowline and commenced extended production on December 10. It is producing 41.5°API light oil and solution gas, consistent with the rest of the field.
These rates were all achieved with a choke size of 16/64 inches (6.35 mm). Prior to tie-in, intermittent production tests flowed total fluid rates of up to 1,200 bpd, with water cuts ranging between 80% and 95% as the well had yet to recover drilling and completion fluids that had been lost to the formation during those operations. As the data indicates, the well is unloading those fluids and as it does, production rates have continued to increase as the water cut falls. Testing will continue until the well has substantially cleaned up and reaches a stabilized flow rate and water cut.
The Winstar-13 well has also commenced drilling in the eastern portion of the Sabria Field approximately 2 km WSW of WIN-12bis, with the same Pergemine rig used for WIN-12bis. The planned total depth is 3,860 meters and the well is expected to take 63 days to drill. It is 30 meters structurally lower than WIN-12bis, although still high relative to the other producing wells in the field.
The Sabria Field covers approximately 11,250 acres and is 45% owned and operated by Winstar Tunisia, a wholly-owned subsidiary of Serinus. The other 55% is owned by the Tunisian state oil company, ETAP.
Jock Graham, executive VP and COO of Serinus said, “We are extremely pleased with the performance of WIN-12bis as the well has exceeded our expectations to this point. We will continue to monitor the well’s performance and look forward to seeing what its ultimate stabilized rate will be. In addition to a material increase to our Tunisian production, this well and WIN-13 will provide new data about the Sabria reservoir, and contribute to the company’s drilling performance. We look forward to the WIN-13 results once it reaches its target depth in February.”
