The Dina formation at Evesham is an estuarine channel complex developed in palaeo-geographic lows on the Devonian unconformity surface. Wells produce oil from shallower zones in the area, but are generally drilled through the Dina formation and logged. As a consequence, excellent control is available to characterize the Dina sand reservoir and to define the oil-water contact. This analysis, along with Tuscany’s high quality 3D seismic database, enabled detailed mapping of the Dina reservoir.
In 2009, Tuscany drilled the initial HZ 2B9-21-39-27 W39 well on a 3D seismically defined high, with the horizontal section drilled between two existing vertical wells with demonstrated oil pay in the Dina. In 2010, Tuscany drilled the second HZ 1A8-21-3B16-16-39-27W3 well that is currently producing at a restricted rate of approximately 80 barrels of oil per day with less than a 10% water cut. This is the second successful horizontal well drilled in this Dina pool, on the 1320 acre prospect. Tuscany is preparing a development plan for the pool. Based on geology and proprietary 3D seismic, full development could require more than 30 horizontal oil wells, with associated surface and water handling facilities. The drilling of the next horizontal well is planned for the second quarter of 2010. Tuscany is the operator and holds a 60 % working interest in the lands.

Horizontal drilling is the only economically viable method to recover Dina oil for
Evesham type pools. Cumulative production from over 190 horizontal wells in the
area averages over 127,000 barrels of oil per well. Analogous pools in the area,
Senlac and Eyehill, have produced 44 million and 9.6 million barrels of oil respectively.
Tuscany’s pool with volumetric oil in place of 60m million barrels will be developed
with 30 to 40 wells, a total capital project of $25-30 million dollars, and funded
over 2 years. Production should be about 1000 Boepd after the project is complete.
