Testing is expected to begin in the second half of May and it is intended that the well will be flow-tested for 30-60 days.
In addition, preparations continue for a single-stage hydraulic fracture stimulation on the Strzeszewo LE1 well - the first of two hydraulic fracture stimulations planned for the site also on the company's Baltic Basin concessions.
The firm's 2013 drilling programme, due to begin in the second half of 2013, involves sinking two further vertical wells, and it is intended that the wells will be completed with a similar DFIT and stimulation programme as on the Strzeszewo LE-1 well.
"We are very pleased that we will shortly be conducting a third phase of testing on the Ordovician horizon in the Lebien LE-2H well. We see this as an important further step in the ongoing appraisal of our western Baltic Basin concessions, which should provide a further indication of this well's reservoir potential," said chief executive Kamlesh Parmar.
"The hydraulic frac stimulation of the Cambrian Alum shale at the Strzeszewo LE-1 well will also yield significant additional data on the potential of the high-graded area within our western Baltic Basin concessions, and will advance our understanding of the potential of the Cambrian Alum shale on our acreage. We look forward to analysing the results of these two operations and updating the market in due course."
