Permian Basin Twin Well - Total Depth and Results

Nostra Terra (AIM:NTOG), the oil and gas exploration and production company with a portfolio of assets in the USA and Egypt, is pleased to announce that its well located in Mitchell County, Texas in the Permian Basin, (the "Twin Well"), has been successfully drilled and logged with oil shows in all of the target formations.

The Twin Well was drilled to a total depth of 3,200 feet encountering the following formations as expected; the Upper San Andres, Lower San Andres, Glorietta, Upper Clear Fork, Middle Clear Fork, and Lower Clear Fork Formations. The well intersected more than 113 feet of gross oil pay in aggregate across the target objectives. In addition, logging indicated potential commercial quantities of pay below the main target zone in the Lower Clear Fork Formation.

The well reached the bottom-hole target as planned. Drilling was successfully completed on time and below budget.

The production casing has been run and the well cemented. The Company will proceed with completion, a production facility upgrade and tie-in operations, following which it  anticipates putting the well put into continuous production.

Matt Lofgran, Chief Executive Officer of Nostra Terra, commented:

"We're very excited for the successful drilling and logging of the Twin Well. We encountered each of the target oil-bearing formations that are productive in the area, including all those seen in the original well drilled by the neighboring operator.

In addition to this well, Nostra Terra has numerous proven undeveloped drilling locations already leased in the same area. We'll seek to grow production and reserves significantly both in the Permian Basin, and other areas of our portfolio."

Notes to Editor:

On 31 October 2017, Nostra Terra announced its third acquisition in the Permian Basin, being the acquisition of a 53.25% Working Interest over a 120 acre lease (the "Lease").

An operator previously drilled a field development well on the neighbouring lease, which produced oil. However, once the operator completed a directional survey of the bottom-hole location it discovered that the well had crossed the boundary of the Lease. The operator of the neighbouring well set a plug back to a shallower depth and completed the well as a saltwater disposal well and has provided all of its data to assist with planning and drilling of the Twin Well.

The drilling and logging operations of the Twin Well were successful, reaching the planned bottom-hole location and intersecting all targeted formations.
