Operations update
3Legs Resources plc ('3Legs' or 'the Company'), an independent oil and gas group focusing on the exploration and development of unconventional oil and gas resources in Poland, announces the following operations update.
Highlights:
Baltic Basin: Lublewo LEP-1ST1H lateral well
· Multi-stage stimulation has now been successfully completed as planned.
· Stimulation comprised 25 stages using a high quality white sand proppant; 7.7 million lbs of proppant delivered over the 25 stages.
· The Company believes this is the largest multi-stage shale stimulation executed to date in Poland.
· The well is now being prepared for clean-up and testing, due to commence shortly.
Operations update
The multi-stage stimulation of the Lublewo LEP-1ST1H lateral well was commenced on 15 July and has now been successfully completed, in accordance with plan. The programme comprised 25 stages and was executed across 1,469 metres out of the available 1,495 metres of lateral section. This compares with the Lebien LE-2H well, the last lateral well drilled by 3Legs which also targeted the Sasino shale horizon, where a 1,000 metre lateral section was stimulated in 2011 with a 13-stage programme.
Approximately 310,000 lbs of high quality white sand were used per stage, equivalent to some 7.7 million lbs over the 25 stages of the stimulation. This compares with 220,000 lbs of sand per stage, or 2.9 million lbs in total, used in the Lebien LE-2H well in 2011. The fluid used was a cross-linked gel, as compared with a slickwater fluid which was used on the Lebien LE-2H well in 2011. The use of a cross-linked gel was designed to reduce the amount of fluid required per stage, while maximising proppant delivery.
The stimulation programme - believed to be the largest multi-stage shale stimulation executed to date in Poland - incorporated the extensive learnings that 3Legs and ConocoPhillips have acquired since first commencing shale drilling operations in Poland's Baltic Basin, in 2010. Over that period, the two companies have drilled a total of eight wells in the basin targeting two different shale horizons, including three long length lateral wells, and they have executed stimulation programmes on six of these wells.
The well is now being prepared for clean-up and long term testing, due to commence shortly, when further announcements will be made.
Kamlesh Parmar, Chief Executive of 3Legs Resources,said:
"We are now into the final phase of our 2013/14 drilling programme, namely the stimulation and testing of our long lateral section at the Lublewo LEP-1ST1H well. We are confident that we have incorporated all the available learnings we have acquired to date into the design and execution of the stimulation programme, and that we have taken all steps to ensure that the forthcoming well test has every chance of
