Russia-focused oil and gas firm Matra Petroleum said production has started on both of its wells in the Sokolovskoe field.Neither well has yet stabilised and, as expected, both will either require acid stimulation or pump installation, or both, to maximise production rates.Well 13 is currently producing around 65 barrels of oil per day (bopd) and well 12 somewhere between 100 and 150 bopd, though flow rates on both wells are fluctuating significantly."Well-12 side-track is producing at broadly similar rates to the original hole prior to acidising and the data from forthcoming pressure surveys should allow us to confirm the potential to improve production substantially. Whilst it is not possible to comment on ultimate production rates at this stage, the original well demonstrated an eight-to-ten fold improvement after acid," Matra's managing director, Peter Hind, said.The company said that adverse weather conditions have delayed the demobilisation of the company's sidetrack rig in Orenburg. The snows have started to thaw now and this will limit heavy load transportation during April while the snow melts and clears."We are currently planning to mobilise a coiled tubing unit to the well sites to ensure the proper clean up and to undertake acidisation as appropriate. This work will commence once the road restrictions associated with the annual thaw are removed," Hind said. ---jh
