Bayfield Spuds Another Well Offshore Trinidad

image

Bayfield Energy, an independent oil and gas exploration and production group with key assets in Trinidad and Tobago, has announced the spud of the second well in its exploration and appraisal programme in the offshore Galeota Licence Area, designated EG7.

The well spudded on 4 April 2012 and is being drilled by the Rowan Gorilla III jack-up rig, following on from EG8, which was suspended as an oil and gas discovery in March following successful drilling results.

The well is located in 112 ft (34 m) of water and lies approximately 800m east of well EG1, which encountered oil in 1964. EG7 is planned to be drilled to a total depth of approximately 8,485 ft (2,586 m, measured depth below rotary table) and will be deviated to the south-east from the surface location to investigate the Lower Pliocene to Upper Miocene stacked shallow marine sandstone reservoirs encountered in the previous discovery wells EG1 (1964) and COS1 (1985).

As in well EG8, several primary exploration targets have been identified by direct hydrocarbon indicators highlighted through reprocessing of 3D seismic data acquired by Bayfield in 2010.

Following completion of EG7, as previously agreed the jack-up unit will revert to Bayfield’s alliance partner in the rig contract. This will allow time for Bayfield to integrate the results from EG7 and EG8 into its evaluation of the Galeota Licence, prior to proceeding with the next phase of drilling.

Bayfield is the operator of the Galeota Licence area holding a 65% interest, with Petrotrin holding the remaining 35%.

Range Resources Reports Further Success at North Chapman Ranch

by  Range Resources – Press Release – Friday, March 09, 2012

Range Resources reported Friday further success in the appraisal and development of the North Chapman Ranch Field onshore Texas (Range 20-25 percent interest), with the successful drilling of the Smith #2 and Albrecht #1 wells.

Initial gross flow rates from the uppermost pay zone, which is one of four principal pay zones, in the Smith #2 well reached more than 3 million cubic feet per day and 125 barrels of oil per day, with more than 7,500 pounds per square inch flowing casing pressure on a 10/64-inch choke. Work is being conducted now to remove all of the plugs below the upper pay zone and combine the remaining lower pay zones to achieve maximum rate and recovery, Range said.

The Smith #2 well was drilled approximately 1,350 feet southeast of the Smith #1 discovery well, further extending the Company’s Proved Reserves in that direction.

The Smith #2 was followed immediately by the Albrecht #1, drilled more than 1,500 feet southeast of the Smith #2. The Albrecht #1 confirmed the presence of the Howell Hight reservoir in that area and is also expected to add significant Proved Reserves to the Company’s portfolio.

With four wells now drilled in the field, Range estimates that over 80 percent of the structural closure at the Howell Hight reservoir falls into the proved and probable (2P) category. Work is currently underway to revise the reserve estimates at North Chapman Ranch, and is expected to be finalized once The Albrecht #1 well comes online. The Albrecht well is scheduled for completion and fracture stimulation within the next four to six weeks.

Once the Smith #2 and Albrecht #1 wells are both online, Range estimates that its net production and cash flow from the project will increase by more than 200 percent over current levels.

Trinidad to Offer Six Blocks in Deep Water Bid Round

image

Trinidad and Tobago’s Ministry of Energy and Energy Affairs (MEEA) has announced that the 2012 Deep Water Competitive Bid Round is tentatively set to open on the 29th of March.

Leading up to the opening of the round, the MEEA will participate in road shows 21st – 24th of February at NAPE 2012 in Houston, 28th – 29th of February at Trinidad and Tobago Energy Trade Mission in the JW Marriot Houston, and the 8th of March at the MEEA delegation to the High Commission for the Republic of Trinidad and Tobago in London where the six selected deep water blocks nominated will be announced.

The six offshore blocks that are to be nominated and offered will come from locations in the East Coast Marine Area and Trinidad and Tobago Deep Atlantic Area (See Concession Map). This acreage offers a mix of water depths, hydrocarbon play-types and production potential.

Available Data

PGS, in conjunction with the MEEA, has acquired 6,766 km of marine MultiClient 2D data over approximately 43,000 sq. km of the Trinidad and Tobago offshore area.

PGS TOBAGO TROUGH MC2D 2008: 2,448 km of ultra-long offset, dual-sensor GeoStreamer 2D data located across 9 blocks in the West Tobago Sub-basin and Tobago Platform.

PGS DEEPWATER ECMA MC2D 2008: 1,966 km of ultra-long offset, dual-sensor GeoStreamer 2D data located across 26 blocks in the Barbados Accretionary Complex on the Trinidad and Tobago Deep Atlantic Area.

PGS NCMA-4&5 MC2D 2008: 2,352 km of high resolution 2D located across the Patao High across 2 blocks in the West Tobago Sub-basin and Southeast Tobago Sub-basin between the Tobago Platform and the Araya-Tobago metamorphic basement.
