HOUSTON, Jan. 3 -- Pacific Stratus Energy Ltd., Toronto, began delivering 35 MMcfd of gas on Dec. 28, 2007, from La Creciente field in Colombia's Lower Magdalena basin to the Guepaje-Sincelejo pipeline.

The company said its La Creciente D-1 discovery well identified a gas-bearing area of 430 acres. The well found the gas-water contact at 10,131 ft true vertical depth subsea, 32 ft below the top of the reservoir.

The well cut 28 ft of net reservoir sandstones with 18.1% average porosity and 38.8% average water saturation. Formation pressure at the top of the reservoir was 6,492 psi, or 150 psi lower than the pressure registered at the same depth on Prospect A.

The company said the Cienaga de Oro formation consists of 483 ft of well-sorted, coarse to fine grain sandstones (upper unit) and an interbedded sequence of silts, shales, and fine grain sandstones.

Meanwhile, Colombia's Agencia Nacional de Hidrocarburos awarded Pacific Stratus the Tacacho Technical Evaluation Agreement, which covers the 1.48 million acre Tacacho block in the foreland basin of the Putumayo mountain range in Colombia's Eastern Cordillera. The area lies along a prominent structural high that trends north-northwest from Ecuador.

The main exploration targets on the block are the Tertiary Pepino formation and Cretaceous Villeta sandstones, prolific producers in the Ecuadorian part of the basin.
