Fracturing technique raises flow in Romanian wells

PLOESTI, Romania -- Petrom has completed a campaign to improve recovery from its Lebada Est and Lebada Vest fields in the Histria block in the Romanian sector of the Black Sea. Following this program, the company expects to achieve additional production this year of more than 300,000 boe from two existing wells (LO2 and LO4) and a newly drilled offshore well, LV05.

Wells L02 and L04 were drilled initially in 1998 on Lebada Est. They had been producing at low rates due to the low permeability of the reservoir rock.

According to Petrom, Lebada Est and Lebada Vest are similar from a geological perspective. The company had applied multi-stage hydraulic fracturing – a pioneering technique for the Romanian sector, it claims – to increase the flow of reservoir fluids from the rock into the wellbores in the LV03 and LV04 wells on Lebada Vest.

Following the resultant improvement in production in both cases, the company decided to drill a new well on Lebada Vest – LVO5 – and to transfer the technique to wells L02 and L04 on Lebada Est.

Petrom currently produces 32,000 boe/d from five fields in the Black Sea, which accounts for around 18% of its overall production in Romania.
