San Leon Registers Highest Frac Pump Rate at Pressure Outside US
UK-based San Leon Energy is determined to continue hydraulic fracture stimulation of the Lewino-1G2 well on Gdansk W Concession in Poland’s northern Baltic Basin, as it registers the highest frac pump rate at pressure ever performed outside the US.
“The initial results and data collection at Lewing-1G2 are very encouraging and easily justify continued operations on the concession. The amount of data collected along with the flow of burnable gas from the well is an excellent result for this initial frac and test at Lewino and exceeded our expectations for San Leon’s first frac in the basin,” Executive Chairman Oisin Fanning commented in a note released on Monday.
The initial vertical frac was performed to test frackability and the flow potential of the lower Ordovician shale. The company wanted also to gain some more data for future horizontal drilling and multi-staged hydraulic fracture stimulation. The frac was performed through a 4.5-meter perforated interval, at a depth of 3,545 to 3,550 meters.
‘The frac pumped over 11,000 barrels of fluid and 95 tons of sand propant at an average of 120 barrels per minute with a maximum pressure of 12,200 psi,’ reads the note.
The Gdansk Concession is located in the gas/condensate window with estimates predicting 98% burnable gas, including methane (75%), ethane (15%) and C3-C10 (8%).
“We are at a critical stage in our shale gas exploration in Poland and we are excited to have flowed gas to surface and to have recovered the necessary information to continue to prove this play,” said Fanning.
San Leon Energy plans additional vertical fracs in Lewino-1G2, estimating operations to take place in early Q4 2013 subject to final design work and regulatory approvals.
Also on Monday, the company proved the presence of mobile oil in the Cambrian tight sand in the Braniewo S Concession in a nearby area.
San Leon Energy edged 4% higher in early deals as it revealed findings of these tests.
