Area Drilling

March 5, 2007


Log evaluation has indicated that the IE-2 appraisal well drilled to TD 8,675 ft subsea by BowLeven PLC’s EurOil Ltd. subsidiary encountered two hydrocarbon-bearing zones.

The well, on Etinde Block MLHP 7 in the Rio del Rey basin, found 50 ft of net gas pay in good quality Miocene Biafra sandstone at 3,310 ft and 130 ft of net gas-condensate pay in good quality Miocene Isongo sandstone at 7,850 ft. EurOil plans to drillstem test the Isongo.

It is the first of four wells to be drilled consecutively (OGJ Online, Feb. 15, 2007).


The government awarded Gold Oil PLC and Plectrum Petroleum PLC, London, an exploration license on Block Z-34 off Peru’s northern coast in the Talara basin.

The block covers 3,713 sq km close to a producing concession and is in 100-3,000 m of water. The companies plan to run electromagnetic surveys and shoot at least 2,000 line-km of 2D seismic surveys in the first 18 months. Gold Oil is operator with 50% interest.


A flow rate of more than 100 Mcfd of gas from a thin gas zone over water at the top of the Cambrian sandstone at 3,616 ft at the Echo 57 deeper pool test in southwestern Ontario provides encouragement for further exploration, said Echo Energy Canada Inc., London, Ont.

The company plugged back and completed the well as a gas well in the Silurian Thorold sandstone, one of 71 wells that have tested gas from Thorold since 2001 in Elgin and Norfolk counties south of Tillsonburg, Ont.

Output is a combined 1 MMcfd from 54 wells, restricted due to soft natural gas prices. Gas produced but not sold is parked in a gas storage account with Union Gas for sale at any time.

Magnetic and gravity surveys acquired in 2006 in Bayham, Houghton, and Malahide townships clearly outline trend areas for deeper targets and Thorold development (OGJ Online, May 16, 2006). The company holds 60,000 acres of leases, one of the province’s largest undeveloped land positions, in the area.

Texas (South)

Comstock Resources Inc., Frisco, Tex., reported 25.5 bcfe of proved reserves and 27.6 bcfe of probable and possible reserves in Las Hermanitas gas field in Duval County.

The company acquired the field at the end of September 2006 at $67 million for three producing wells and 18 drilling locations and drilled two wells in the last quarter of 2006. The proved and possible reserves relate to 10 drillable locations.

The company plans to drill 21 wells in 2007 in South Texas, where it had 10 successful completions in 2006 that averaged 5.6 MMcfd in Ball Ranch, Javelina, and Las Hermanitas fields.
