US firm San Leon excited about shale gas flow testing at Poland’s Lewino well

Oil and gas exploration firm San Leon Energy could likely prove commercial flows from its Lewino-1G2 well in the Baltic Basin in northern Poland by October following a 10-stage frack of a planned horizontal well, officials from its oilfield operating partner United Oil Services (UOS) told reporters in Warsaw.

San Leon reported a sustained gas production rate of 45 000–60 000 standard cubic feet per day (scf/d) after six weeks of partial well clean-up on a fracked vertical well, and estimates 200 000 – 400 1000 scf/d would be the rate from a fully-cleaned well.

“It’s a major milestone in development of the commercialisation of unconventional gas in Poland,” UOS chief Dennis McKee said of what he calls the largest continuous flow rate seen in any Polish operations to date.
