– Two companies encountered oil in four Jurassic zones and ran production casing to 1,100 ft to test an indicated discovery in Grand County, Utah, in the northern Paradox basin.

Tidewater Oil & Gas Co. LLC, Denver, and Forest Gate Energy Inc., Montreal, drilled the Tidewater-State well, in 3-22s-19e, 20 miles west of Cisco Dome field, to a TD of 3,050 ft to Triassic Wingate sandstone (OGJ Online, Jan. 25, 2010).

Forest Gate reported the following results from a third party evaluation of the well on its Crescent Junction property:

• 40 ft of potential oil pay at 390-430 ft with 28% porosity and a calculated 37% water saturation in the Brushy Basin member of the Morrison formation.

• 50 ft of potential oil pay at 770-820 ft with 20% porosity and 39% water saturation in the Lower Salt Wash member of Morrison.

• 10 ft of potential oil pay at 830-840 ft with 20% porosity and a calculated 37% water saturation in the Lower Salt Wash.

• 30 ft of potential oil pay at 870-900 ft with 20% porosity and a calculated 50% water saturation in the Lower Salt Wash.

The Brushy Basin and Lower Salt Wash have produced oil for many years at Cisco Dome field, Forest Gate noted. The well also yielded important data to help target the Wingate at future wells, the company said.

Forest Gate holds varying interests in 121,000 gross acres and 31,335 net acres in Utah and has an option to acquire a 50% interest in a further 135,505 gross acres and 37,264 net acres in the state.
