The Parmer prospect #1 is located on Green Canyon 867, at a depth of 18,900 ft (5,760 meters), which allowed for several pressure readings and the collection of several fluid samples from Miocene sands. The data indicate a column of approximately 240 ft (73 meters) of net condensate-rich gas pay, as prospect as one of 40 ft (12 meters) of net oil pay. In the coming months, Ecopetrol and its partners will reprocess 3-D seismic data and determine a comprehensive delimitation and development plan according to these results.
The two Parmer leases (GC 823 and GC 867) are located within the Green Canyon protraction area, at a depth of approximately 4,200 ft (1,280 meters) underwater. Each covers an area of 5,760 acres (23.3 square kilometers) and is located approximately 143 miles (230 km) from Louisiana.
Ecopetrol America has a 30% interest in the Parmer Prospect. Its partners are Stone Energy, and Apache that is the prospect’s operator.
The Parmer discovery is Ecopetrol’s second deepwater discovery in the Gulf of Mexico, one of the regions with the highest oil hydrocarbon potential in the world.
The results are expected to assist in Ecopetrol S.A.’s strategy to attain a production level of 1.0 million clean barrels of oil equivalent a day by 2015, and 1.3 million clean barrels by 2020.

The Company has 100% working interest in the block and is the operator.
Ronald Pantin, Chief Executive Officer of the Company commented: “this is an important exploration discovery for Pacific Rubiales and demonstrates the potential of both the Guama block and Lower Magdalena basin where the Company has a large exploration acreage position and is looking to increase its gas reserves to support its initiative to develop an LNG export market in the future.”
The Cotorra-1X well was drilled as an exploratory well after an earlier exploration success on the block, the Pedernalito-1X well drilled in 2010. The well targeted Porquero Medio sands and silts of Miocene age, a low-permeability play successfully tested by Pedernalito-1X. Cotorra-1X was drilled to a total depth of 7210 feet in mid-January. The petrophysical evaluation showed a total of 40 feet of net pay, with average 20% porosity.
The well was perforated only in the deeper pay zone, across two intervals; leaving overlying pay zones untested for further evaluation.
After clean-up while flowing through a 1/2″ choke, Cotorra-1X reached a maximum gas flow rate of 7.5 MMcf/d and 370 bbl/d 56 degrees API condensate, followed by a three-stage isochronal and one extended flow test through 12/64″ choke which flowed at 2.6 MMcf/d and 121 bbl/d condensate at 3137 psi well head pressure.
During the month, the Company also completed drilling the Apamate-2X exploration well on its 100 percent owned and operated La Creciente Block. The well failed to test hydrocarbon flow at economic rates and was plugged and abandoned.

McMoRan Exploration Co., a shallow water Gulf of Mexico exploration company, reported yesterday that its Lafitte ultra-deep prospect, which is located on Eugene Island Block 223 in approximately 140 feet of water, has encountered additional hydrocarbons.
The well has been drilled to a true vertical depth of 29,756 feet and has been logged with wireline logs to 29,740 feet. The wireline log results indicated 56 net feet of hydrocarbon bearing sand over a 58 foot gross interval in the Cris-R section of the Lower Miocene with good porosity. Flow testing will be required to confirm the ultimate hydrocarbon flow rates from this zone, which was full to base. McMoRan controls approximately 15,000 gross acres in the immediate area of Lafitte.
The new Cris-R sand interval combined with the 115 feet of potential net pay (250 gross feet) announced previously brings the total possible productive net sands to 171 feet in the Lafitte well. These results enhance the potential of McMoRan’s other acreage in the Lafitte strategic area, including McMoRan’s Barataria and Captain Blood ultra-deep prospects. Barataria (10,000 gross acres) is located westsouthwest of Lafitte and Captain Blood (10,000 gross acres) is located immediately south of Lafitte.
McMoRan plans to apply for a permit to deepen the Lafitte well to a proposed total depth of 32,000 feet to evaluate deeper Miocene and Oligocene objectives. Lafitte is McMoRan’s third ultra-deep prospect to encounter Miocene age sands below the salt weld on the GOM Shelf. McMoRan holds a 72.0 percent working interest and a 58.3 percent net revenue interest in Lafitte. Other working interest owners in Lafitte include Energy XXI (NASDAQ: EXXI) (18.0%) and Moncrief Offshore LLC (10.0%).
McMoRan Exploration Co. is an independent public company engaged in the exploration, development and production of natural gas and oil in the shallow waters of the GOM Shelf and onshore in the Gulf Coast area.

Bowleven, the West Africa focused oil and gas exploration group traded on AIM, on Friday (October 14) announced the discovery of oil at the Sapele-3 exploration well drilling in the Douala Basin, offshore Cameroon.
Sapele-3 drilling update
The Sapele-3 well is located circa 16 kilometers North West of Sapele-1 and circa thirteen kilometers North West of the D-lr wells. The well is drilling in water depths of approximately 30 meters.
The well was initially designed to target the shallower Miocene play including the reservoir interval previously encountered at Dl-r. Due to optimised well design it has also been possible to deepen the well into what is the Deep Omicron equivalent interval encountered with previous Sapele wells.
Bowleven, as operator, provides updates for the reservoir intervals encountered at Sapele-3 below:
Deep Omicron interval (oil)
The well has encountered 11 meters of independently log evaluated hydrocarbon pay in high quality sandstone reservoirs within the Deep Omicron stratigraphic interval intersected by previous Sapele wells. In addition, a further 24 meters of net sand was encountered, of which up to 11 meters is currently interpreted as having either a high residual hydrocarbon or a hydrocarbon bearing response from logs. Further evaluation to determine whether this is pay or not is pending.
Wireline logs indicate that the majority of reservoir has been encountered within two distinct packages within the upper part of the Deep Omicron interval that can be correlated to the earlier Sapele discovery wells. The logs also indicate high net to gross ratios through these packages.
As the well is only two thirds of the way through the Deep Omicron interval and has encountered excellent quality oil bearing reservoir at current total depth (TD), the intention is to recommence drilling to the base of Deep Omicron. The presence of light oil at current TD has been confirmed by sampling. Testing plans will be assessed on reaching final TD. The confirmed presence of oil in the Deep Omicron interval at Sapele-3, 16 kilometers from the original Deep Omicron discovery at Sapele-1, extends the currently mapped Deep Omicron fairway significantly Northwards into MLHP-6. Consequently a significant increase in current Deep Omicron in-place volumetrics is anticipated.
At the shallower Miocene (Dl-r) equivalent interval target, a 7 meter high quality sandstone was encountered with a I meter gas-condensate column. The extent and size of the discovery is worthv of further evaluation.
Kevin Hart, Chief Executive of Bowleven plc commented:
“We are excited with results so far at Sapele-3. The Deep Omicron interval continues to deliver and the confirmed presence of oil and good quality reservoir at this location further emphasises the significance of this play within the Douala Basin. All four Sapele wells drilled have now encountered oil within the Deep Omicron interval, thus reinforcing the geological model and highlighting the overall development and exploration potential of the fairway. This well has also now shown that the Deep Omicron interval extends considerably beyond the currently mapped area which has significant implications in terms of both volumetrics and prospectivity potential on both block MLHP-5 and MLHP-6. In addition, the gas condensate discovery at the Dl-r interval is promising and warrants further evaluation.
The results at Sapele-3 represent another step towards our overarching strategy of converting resources to reserves whilst highlighting the extensive exploration potential in the basin. We look forward with eager anticipation to the further drilling planned at Sapele-3.”

Total announces that its subsidiary, TEPA (Block 17/06) Limited, and Sociedade Nacional de Combustíveis de Angola (Sonangol E.P.), have discovered hydrocarbons in the north-eastern area of the deep offshore block 17/06.
Drilled in a water depth of 445 meters, the Canna-1 well discovered hydrocarbons in reservoir of Miocene age and produced more than 5,000 barrels per day of high quality oil (33° API) during a production test.
Sociedade Nacional de Combustíveis de Angola (Sonangol) is the concessionaire of the Block 17/06. TEPA (Block 17/06) Limited is the operator of the Block 17/06 with a 30% stake. Total’s partners in the block are Sonangol Pesquisa e Produção S.A. (30%), Sonangol Sinopec International (SSI) Seventeen Limited (27.5%), ACREP Bloco 17 S.A. (5%), Falcon Oil Holding Angola S.A. (5%) and PARTEX Oil and Gas (Holdings) Corporation (2.5%).
Total Exploration & Production in Angola
Total is present in Angola since 1953. In Angola, Total operated 460,000 barrels oil equivalent per day (boe/d) in 2010, and its SEC* equity production amounted approximately 163,000 boe/d. This production comes essentially from Blocks 17,0 and 14.
Deep offshore Block 17, operated by Total with a 40% interest, is Total’s principal asset in Angola. It is composed of four major zones: Girassol-Rosa and Dalia, which are currently producing; Pazflor, a project under development for a production start in the second half of 2011; and CLOV (based on the Cravo, Lirio, Orquidea and Violeta discoveries), for which the development was recently launched.
Total is also the operator with a 30% stake in the ultra deep offshore Block 32, on which 12 discoveries were made, confirming the oil potential of the block. Pre-development studies for a first production zone in the central south eastern portion of the block are underway.
In addition, the Angola LNG project for the construction of a liquefaction plant near Soyo is designed to bring the country’s natural gas reserves to market. This project, on which Total holds a 13.6% stake, will be supplied by the associated gas from the fields on Blocks 0, 14, 15, 17 and 18. The project is underway with production expected to begin in 2012.
In Angola, as in all countries where Total operates, the Group is committed to developing the Angolan oil industry while recruiting and providing professional training to local workers. Through its ambitious “Angolanisation” and technology transfer plans, Total has strengthened the local economy and made of Hygiene, Safety and Environment awareness a top priority. Total E&P Angola has developed a transparent and solid corporate social responsibility policy around three main axes: health, education (opening of four high schools in the provinces in 2009) and economic community development.
