San Leon delivers Poland's shale vertical with breakthrough frac design from SIGMA3

SIGMA3 (Sigma Cubed Inc.) provided the stimulation design and dynamic simulation modeling and onsite stimulation expertise for the San Leon Energy Plc (SLE) Lewino-1G2 shale gas well in Poland's Gdansk W Concession. With predictions of 200,000 to 400,000 scf/day, SLE described this project as the country's most successful vertical frac to date and is moving quickly to plan the first Lewino horizontal well with multi-frac stages. SIGMA3 was part of a services team led by United Oilfield Services (UOS).

After testing two frac strategies in the lower Ordovician, SLE's objective for the stimulation program in the upper shale interval was to prove the ability to fracture and enable sustained production. The same strategies would then be applied to a multi-stage stimulated horizontal well in the lower Ordovician -- which has superior gas saturation and porosity -- intended to open the upper and lower intervals and deliver consistent commercial flow rates.
