Echo Energy has announced the discovery of a ‘notable gas column’ while testing its fourth well in the company’s Argentina drilling campaign.
During exploration, the company encountered the targeted Upper Jurassic Tobifera formation, with observations of extensive gas and light hydrocarbon shows. The CSo-2001(d) well, located in the Fracción D project area, was drilled to a depth of 1,511m.
Echo said it measured 60m of gas shows through this formation, with readings peaking at 168,000 parts per million and full distribution of C1 to C5 hydrocarbon shows.
The company told Offshore Technology: “The four-well exploration campaign has exceeded expectations with hydrocarbons (gas and or oil) in each of the four wells drilled interpreted from the wireline log data. The test rig has been mobilised and we are looking forward to getting on with a busy testing period following which the wells will be brought onto production.”
Wireline logging has indicated around 30m of net gas pay in the well, said to be in the “upper end of the range” used in previously conducted contingent and prospective resource estimations. Together, these made up around 38 billion cubic feet of gas.
Echo Energy chief executive Fiona MacAulay said: “I am delighted that our fourth well in the current drilling campaign has again successfully interpreted a notable gas column in the Tobifera.
“With the Quintana 01 completion and testing rig mobilising to the area this week we will be able to test this interval within the forthcoming testing sequence, enabling an early decision to be made on monetisation options in Fracción D.
“We are now looking forward to commencement of testing on the ELM 1004 well, which will be the first well to be tested in this programme.”
The next step for Echo is to carry out a production casing, before a planned testing programme that will use a separate rig due to come under contract this week.
