HOUSTON, Apr. 25 -- A Canadian independent operator set 7 in. casing at its second exploration well in the Sandino basin of western Nicaragua after encountering 271 ft of conventional pay in 10 zones.

Tests will begin in a few days. Norwood Resources Ltd., Vancouver, BC, said the pay is evident from petrophysical and core analysis on various turbidite sands of the Paleocene Brito formation. The core work indicated porosities of 16-24% and permeability of 2 to 75 md. The porosity values agree favorably with the log measurements, Norwood said.

The Las Mesas Gutierrez-1 well, 11 km west of and on a separate structural closure from the company's first well in the area, went to TD 9,880 ft with 14.1° bottomhole deviation (OGJ Online, Feb. 27, 2007).

Following tests, the company plans to test the initial San Bartolo Rodriguez Cano-1 well while it prepares a third location for drilling.

The first well was assigned a combined 532 ft of pay, including 232 ft of conventional pay and another 300 ft of naturally fractured low permeability sands in eight separate zones with 17-21% porosities and 3-30 md permeability.
