San Leon Energy is readying to spud a horizontal well offsetting a multi-stage fracking campaign following successful flow testing of its Polish shale formation.
The Lewino 1G2, in the Gdansk West concession, Poland’s northern Baltic Basin, has been producing gas at a steady rate of 45,000-60,000 standard cubic feet per day over the six weeks of well clean-up following the successful frack.
The well, which only started producing after the third frack in the Ordovician shale conducted last year, is expected to flow at 200,000-400,000 scfd when the clean-up of the fracking fluid is complete.
Clean up work on the site has been halted due to costs of more than £33,000 a day as the company prepares to drill a 1,500m horizontal well – estimated to produce from 7-30 times more output than vertical wells, based on US examples – with a multi-staged frack programme.
“This is the most encouraging vertical shale well test in Poland to date,” said Oisin Fanning, San Leon’s executive chairman.
“We have moved a long way towards “cracking the code” towards commercial production from our unconventional plays.
“These learnings will be put to good use in the planned multi-staged fracked horizontal well in the Lewino area, where we believe we shall be able to stimulate the entire vertical extent of the Ordovician interval with each frack, and prove commercial flow rates.”
Alongside the steady gas production, an output of 20 barrels of condensate per every million scfd was recorded which would add around 20% of additional revenue to future gas sales, the company estimates.
