Ascent Resources recently reported that PetroHungaria kft, in which it has a 48.3 per cent interest, has completed the drilling of the PEN-105A sidetrack in the Penészlek Project in Eastern Hungary.
The results of the well have exceeded management’s expectations and are better than the original PEN-105 well, with approximately 20m of gas bearing formations drilled in the targeted Miocene volcanicastic reservoirs.
The PEN-105A well was sidetracked from the existing PEN-105 well to a measured depth of 1640m and a location some 460m northeast of the original well. It was designed to drain gas reserves from the northern half of the structure, which is bisected by a sealing fault. The original well has recovered some 0.85 Bcf (24 Mm3) of gas from the smaller southern part of the structure since production started from it in March 2010.
Preliminary testing of a 7m perforated section of PEN-105A produced gas at a rate of 0.928 MMscfd (26,300 m3/d; 154 boepd) and work now progresses to reconnect the well to the production facilities.
Ascent’s managing director, Jeremy Eng, commented: “This PEN-105A performance is a good result and can be expected to prolong the production from the Penészlek field for at least a couple of years. Gas prices in Hungary are strong and this production will provide very useful revenue to the Group pending the start-up of joint venture production from the Petišovci Project in Slovenia”
