Aurelian Oil & Gas (LON:AUL) today revealed a new gas discovery in the Krzesinki-1 exploration well on the same licence as the Siekierki tight gas field in Poland.
It said that wireline logging has been completed and the well is being prepared for testing. Based on what it knows so far Aurelian believes the discovery contains between 10 and 20 billion cubic feet of gas in place.
The Krzesinki-1 testing will be complete by the end of this year.
"We are pleased to have discovered gas in the Krzesinki exploration well which is located 8 kilometres from our multi-fracced horizontal well (MFHW) Trzek-3,” said chief executive Rowan Bainbridge.
“The discovery is expected to be tested this year and we will provide a further update when this testing is complete. This well will also provide valuable data to assist our ongoing assessment of the wider Siekierki tight gas field.”
The Krzesinki-1 well was targeting a separate reservoir to Siekierki, although they are both in the same age rocks. The well encountered a 65 metre gas column, and the company said that 175 metres of core has been recovered.
Aurelian added that from the extensive quantity of core, it has so far yielded measured ambient porosities between 5 and 16 per cent, and ambient permeability between of 0.04 mD to 40.0 mD.
Additionally the company told investors that it has hired a specialist tight gas team, from industry consultancy AGR, to work alongside its in-house technical team. The AGR team will carry out a detailed, bottom up review of all existing data on the Siekierki field so that it can assist in the development of an updated appraisal plan for the Sierkierki project.
“We are also looking forward to working with AGR and believe that their significant experience with tight gas reservoirs will greatly assist our thinking as we work towards preparing a revised appraisal plan for the wider Siekierki structure,” Bainbridge said.
Meanwhile in Romania, on the Brodina licence, the Horodnic-1 exploration well has been spudded. The well follows up the Voitinel-1 discovery well which was drilled in 2009.
The well will test the late Badenian sandstones which successfully flowed gas in the Voitinel-1 discovery in 2009. It is being drilled around 2.5 kilometres to the southeast of Voitinel-1 and it is targeting a mid case gross gas-in-place of 52 billion cubic feet.
Bainbridge added: “In Romania we have also spudded Horodnic-1, the second well on the Voitinel trend following the 2009 discovery at Voitinel-1.
“We will provide an update on this well in late November or early December."
