Salamander Sees Gas Shows at Thai Well
Friday, April 15, 2011
Salamander Energy plc
Salamander provided the following update on its Thai drilling operations in Block L15/50, onshore Northeast Thailand, and Block B8/38, Gulf of Thailand.
Dao Ruang-2 well, Block L15/50
Dao Ruang-2 ("DR-2") drilling operations at the Dao Ruang-2 location have been completed. Following an openhole drill stem test ("DST") the well failed to flow at a sustained commercial rate and is in the process of being temporarily suspended for potential re-entry at a later date. Drilling now moves to the second location of the two well program, as originally planned, targeting an independent fault network in the structure.
The DR-2 well was drilled to a depth of 2,212 meters true vertical depth sub-sea ("m TVDSS") into the eastern flank of the Dao Ruang structure, targeting a swarm of faults and fractures identified from high resolution 3D seismic. The well intersected a number of fracture zones with associated gas shows and experienced gas influx associated with a fault system around 1,840 m TVDSS. Gas shows were seen all the way to TD, with no sign of water, demonstrating a significant gas column in the Dao Ruang structure.
An openhole DST was undertaken across an interval between 1,008 - 2,211 m TVDSS. The section was tested following an acid wash, however only sub-commercial flow rates were recorded, indicating very low permeability formation and a limited open, connected fracture network at the DR-2 location.
The MB Century 26 rig will now be mobilized to the Dao Ruang-3 ("DR-3") drilling location. The DR-3 well will target a separate fracture set on the northern flank of the Dao Ruang structure with a different orientation to those seen in DR-2, providing a greater chance of encountering an open fracture network and an opportunity to test at a commercial flow rate.
The DR-3 well will be drilled to a planned depth of 1,900 m TVDSS and is expected to spud within the next 8 days. The well is forecast to take 45 days to drill on a dry hole basis.
Salamander has a 50% interest in, and is operator of, Block L15/50.
James Menzies, Chief Executive Officer of Salamander Energy, said, "While it is disappointing that we did not encounter commercial gas at our first Dao Ruang location, it is clear from drilling that there is a significant gas column in the structure. The two well program was originally designed to target two independent fault networks in different orientations, and we expect to spud the second well in a matter of days."

Egdon Commences Drilling Ops at Keddington Field

Egdon Resources plc
Egdon announced the start of drilling operations at the Keddington oil field on Lincolnshire License PEDL005(Remainder).
Egdon holds a 75% interest in and is operator of the PEDL005(Remainder) license. The joint venture partners are Terrain, holding a 15% interest and Alba, a wholly owned subsidiary of Nautical Petroleum, with a 10% interest.
The Keddington-4 well will be drilled as a re-entry and horizontal sidetrack from the Keddington-1Z "donor" well, which was drilled by Candecca Resources in 1998. This oil production well has been shut-in since the drilling of Keddington-3 and 3Z in April 2010. Keddington-4 is planned to penetrate approximately 200 meters of producing Unit 1 sandstone in a new horizontal section. The well is also planned to penetrate the deeper "Namurian" sandstones, which had gas indications in Keddington-3 to provide additional information on this potential gas bearing zone.
The British Drilling and Freezing Limited BDF28 drilling unit began mobilizing to the site on April 1, and operations began on April 4. The plugging-back of the existing well has been completed and the drilling of the sidetrack commenced at 0700 hours on April 9, from a kick-off depth of 2080 meters. The well is intended to be drilled directionally to a total measured depth of around 2750 meters. Drilling and completion operations are expected to last a total of around three weeks.
The well is expected to be completed for free-flowing or pumped production using the existing surface production facilities shortly after the rig is released from the site.
Keddington-4 is designed to increase total field production at a time of high oil prices and provide additional reservoir information in an untested part of the structure to factor into the investment decision on the scale of the gas to electricity generation project planned for the field. This is expected to provide an important additional revenue stream and eventually will enable unconstrained production of oil from the field.
Production from the adjacent Keddington-3z well has been suspended for safety reasons during the drilling operations and will resume once the rig has been demobilized from site and the flow characteristics of Keddington-4 has been determined.

Samson O&G Closes Asset Sale, Sets Frac Date for Earl Well
Samson O&G Closes Asset Sale, Sets Frac Date for Earl Well
Thursday, March 31, 2011
Samson O&G Ltd.
Samson O&G has closed its previously announced sale of gas assets in the Jonah and Lookout Wash Fields in Green River Basin, Wyoming for $6.3 million to a group of private buyers, with an effective date of January 1, 2011. Samson's cash balance following this transaction stands at US $73.3 million.
Samson has also been advised that a frac date has been set for the Earl #1-13H well and it is expected that frac operations will commence Monday April 4th. Earl #1-13H was previously drilled to a measured total depth of 17,342 feet, and a 5,700 foot liner set in the horizontal section. This horizontal section will be fracced with 20 stages and the treatment is expected to place 2.3 million pounds of proppant. This operation will take approximately five days.
