Horse Hill-1 will test a number of conventional stacked oil targets at the proven productive Portland sandstone, Great Oolite limestone and Corallian
During 1991 the Palmers Wood field had a high production of 1400 BOPD, with the reserves being located within the upper Jurassic rocks of the Corallian
Sandstone at about 3,440 feet TVD ss.
