Coastal Energy Encounters Net Pay Offshore Thailand

image

Coastal Energy, an international oil and gas exploration and production company with assets in Thailand announces the successful Miocene discovery in the Bua Ban South A-04 well.

The Bua Ban South A-04 well was drilled to a depth of 3,250 feet TVD on the eastern flank fault block at Bua Ban South, approximately 1.5 miles south of the Bua Ban Main A-11 well. The A-04 well encountered 42 feet of net pay in the Lower Miocene M75 and M100 sands with 29.5% average porosity. The M75 is a newly discovered pay sand in the Lower Miocene. Initial results indicate that this is an extension of the Miocene reservoir which was encountered in the Bua Ban Main A-11. The A-11 well has been producing since September 2010 and is currently producing over 500 bopd. The minimum areal extent of the closure is approximately 550 acres.

Randy Bartley, President & Chief Executive Officer, commented:

“We are greatly encouraged by the successful Miocene results in the A-04 well. We have now discovered oil in three different Miocene intervals between Bua Ban Main and Bua Ban South. This new discovery is very positive for the Miocene remaining potential across the entire basin as well as supporting the potential of recent Oligocene discoveries in the Bua Ban South area. The Bua Ban South A-03ST#1 well has been spudded and will test the Eocene objective. We are currently evaluating locations for Miocene appraisal wells and will begin drilling those following the A-03ST#1.”

Brazil: OGX Encounters Huge Hydrocarbon Column in Santos Basin

image

OGX, a largest privately owned oil & gas company in Brazil, today announced that it has identified the presence of hydrocarbons in the Albian and Aptian sections of well 1-OGX-63-SPS in the BM-S-57 block, in the shallow waters of the Santos Basin. OGX holds a 100% working interest in this block.

“This discovery is important for its huge hydrocarbon column and net pay identified in the Albian section, as well as by the quality of the Aptian reservoir and its behavior,” commented Paulo Mendonça, General Executive Officer and Exploration Officer of OGX.

A hydrocarbon column of approximately 1,000 meters was encountered in Albian reservoirs with about 110 meters of net pay. The drilling of the well, which is still in progress, already reached the Aptian section of the reservoir identifying hydrocarbons through a high gas presence that resulted in a kick, which is already controlled.

The OGX-63 well, known as Fortaleza, is still in progress and located in the BM-S-57 block and is situated approximately 102 kilometers off the coast of the state of Rio de Janeiro at a water depth of approximately 155 meters. The Ocean Quest rig initiated drilling activities on October 08, 2011.

USA: McMoRan Encounters More Hydrocarbons at Lafitte Prospect

image

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.

USA: McMoRan Encounters Hydrocarbon Bearing at Lafitte Well

image

McMoRan Exploration Co. today announced results from interim logging operations at the Lafitte ultra-deep exploration well located on Eugene Island Block 223 in 140 feet of water. The Lafitte well commenced drilling on October 3, 2010 and has been drilled to 27,038 feet.

Wireline logs indicate several Lower Miocene sands below 24,300 feet that appear to be hydrocarbon bearing. The sands have various thicknesses that aggregate approximately 200 gross feet (95 feet net), some of which are contained within a thin-bedded, sand-shale formation (i.e. laminated section).

These Lower Miocene aged sands are correlative to Lower Miocene sands seen onshore and in the deepwater of the Gulf of Mexico and provide additional confirmation of McMoRan’s ultra-deep geologic model. Lafitte is McMoRan’s third ultra-deep prospect to encounter Miocene age sands below the salt weld on the Shelf of the Gulf of Mexico.

McMoRan is preparing to set casing in the Lafitte well to 27,000 feet and plans to deepen the well to a proposed total depth of 29,950 feet to evaluate deeper Miocene objectives and possibly the Oligocene section. McMoRan holds a 72.0 percent working interest and 58.3 percent net revenue interest in Lafitte. Other working interest owners in Lafitte include: EXXI (18.0%), and Moncrief Offshore LLC (10.0%).
