Serinus Energy Inc. report an update on its drilling program in Sabria Field in central Tunisia.
The Winstar-12bis well (WIN-12bis) was tied into the flowline and commenced extended production on December 10, 2014. 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 bbl/d, 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 in the table above indicate, 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.
