Nostra Terra, the AIM oil and gas producer, building its portfolio of working interests (WI) in US oil fields, announced a progress update on the High Plain Prospect, located in Texas. Based on encouraging results, the Company has acquired additional working interest and is moving forward in the defining prospects.
The High Plains Program covers a contiguous area of 42,000 acres (66 square miles), where subsurface mapping, 3D seismic, vertical and horizontal drilling and completion technologies have successfully been applied to several different formations. The WI partners will seek to increase success rates through the application of a new "proof of concept". The region was noted in the $2.85 billion purchase of Cordillera Energy Partners by Apache Corporation in January 2012.
Re-entry - Positive Results
The WI partners suspected that a previously drilled well, which was intended to test the concept, was mis-drilled. The first step of the current program was to re-enter the well in order to validate that the previous well had not tested the exploration model. The re-entry confirmed that the original well missed its target by a wide margin.
Seismic Program Advancing
Accordingly the WI partners are now reprocessing 35,000 acres of proprietary seismic data, integrating that with 42,000 acres of detailed subsurface mapping, and identifying other potential drill targets. The WI partners expect to identify multiple prospect areas within the Area of Mutual Interest (AMI), each of which could comprise up to 2,500 acres and each with multiple drilling locations.
Additional Interest Acquired
Nostra Terra has also increased it's working interest from 5.0 to 6.5 percent across the entire prospect.
Highlights of the High Plains Prospect include:
Alden McCall, chief operating officer of Nostra Terra, commented:
"We're excited about what we learned from the re-entry and further testing will now take place as we move forward. When the opportunity to increase our working interest arose, it was exercised because of the tremendous potential we believe this area has. We now have a 6.5 percent working interest in the overall exploration program as a result. The program will integrate detailed subsurface mapping with 3D seismic further defining our exploration model. This will take several months to accomplish, after which we will prioritize the prospect areas that result for drilling. Due to the nature of the play, this prospect could provide opportunity to build a healthy pipeline of drilling locations for years to come, adding nicely to Chisholm Trail and other prospects in our portfolio."
