Project Profile
Value: Undisclosed
Location: High Island Area, Block 268A, offshore Texas in the Gulf of Mexico, USA
Reserves: Unknown
Water Depth: 169 feet
Start-up Year: -
The High Island field is a gas and oil field located in 169 feet of water offshore Texas in the Gulf of Mexico in the High Island Area, Block 268A. The field is surrounded by a number of producing fields and associated oil and gas infrastructure. Oil and gas was discovered and wire line tested in several reservoirs in six wells drilled on the High Island field between 1984 and 1989, but was not produced due to low commodity prices at the time and perceived reservoir continuity risk. All wells were previously drilled on 2D seismic. The acquisition of 3D seismic in 1995, and its modern re-processing in 2004, has allowed the known reservoirs to be individually defined, significantly reducing reservoir continuity risk. Drilling of the High Island A-1 well was completed in January 2007 and discovered commercial gas in high quality reservoir sands in two separate reservoirs. The High Island A-1 well was cased and temporarily suspended pending the installation of a production platform and pipeline.
The design and fabrication of the High Island HI-268A unmanned production platform and jacket was completed in early June 2007. The installation of the platform commenced in late June and was completed on 7 July 2007. A 5km subsea production pipeline from the HI-268A platform to a regional processing facility was laid by the operator during July 2007. The High Island A-2 well was successfully drilled and completed in late July 2007. Following the completion of flow testing and pressure build-up activities, the well was placed on production on 15 September 2007. The well was completed over a shallower and deeper horizon. The well is currently only producing from the lower reservoir sands. Once the pressure in these deeper sands naturally depletes through production, the sliding sleeve over the upper sands will be opened and the well flowed from the upper sands. Following the drilling and completion of Well A-2, the rig re-entered Well A-1 and completed it for production over the deeper reservoir. Upon completion of testing activities, Well A-1 was placed on production on 7 September 2007. The prospect of a third development well at High Island will be considered by the joint venture following an analysis of data generated from the recent drilling campaign and production results. Elixir holds a 30% working interest in the High Island Project, with Swift Energy holding the remaining interest.
