Jean H. Freeborn-1 spuds
Posted: 24 September 2007
Antares Energy reported that the Jean H. Freeborn-1 well, the first on the Rowena Wilcox prospect, spud on 20 September 2007 local time, and has drilled to a depth of 3,025 fee.
Current operations are setting 13 3/8” surface casing. This well is prognosed to drill to a depth of 16,000 feet to test a very large Wilcox objective in Jim Wells County, Texas.
The well should take between 45-60 days to complete on a trouble free basis.
"In the success case this well will be transformational for Antares Energy," said Mr. Howard McLaughlin, Managing Director of Antares Energy Limited.
"We are very excited to announce the drilling of this prospect and are pleased we are able to drill it with a turnkey contract. To be testing a structure this large only 11 miles from a similarly successful field in an environment of high gas prices is a truly great opportunity."
Antares has a 50 per cent working interest in this project. If successful this project has the potential for a large number of follow up wells. Project potential is in excess of 200+ BCF (Billion cubic feet).
Antares Energy and the operator, San Isidro Development entered into a turnkey drilling contract with Orion drilling to drill a 16,000 foot test well for a fixed cost of USD 4.9 million.
The Rowena prospect is a massive 13,000 acre closure approximately 15 kilometres (11 miles) from the 200+ BCF Hostetter Field. Antares’ minimum financial commitment is anticipated to be approximately USD 2,850,000 dry hole cost.
The main objective of the large seismic acquisition program acquired last year over Shaeffer Ranch was to confirm the presence of a large un-drilled structural closure at the Eocene upper Wilcox level.
This acreage is in a very attractive hydrocarbon fairway within close proximity to several large producing gas fields.
The 3D mapping confirmed the Rowena feature to be a significant and robust structural high with positive seismic geometries and amplitudes.
There is geological uncertainty in sand distribution due to the lack of nearby well control however this prospect is within 11 miles of the successful Hostetter field that has reserves in the order of 200+ BCF and daily production of 50 MMcf/d from the same section and depth targeted in Rowena.
There are other upper and middle Wilcox fields in the immediate area that are of a similar structural style.
From a seismic perspective the section that contains the gas in Hostetter is very similar in character to the interval seen in the Rowena prospect.
Hostetter produces from a number of intervals to depths greater than 15,500 feet.
