The field, in which Providence holds a 20% equity interest, is operated by Star Energy Plc and is located within the Weald Basin in the South of England. These new horizontal wells were designed to develop reserves not presently accessed by the existing revenue generating production wells. The wells which involved the application of extended reach technology were drilled utilizing the Marriott-7 drilling unit.
The objective was to increase daily oil production by between 50% to 100%.
Tony O'Reilly Jr., CEO of Providence commented:
The Singleton oilfield is situated onshore UK in the Weald Basin, West Sussex. Providence holds a 20% equity interest in the field, which is operated by Star Energy Plc. The field, which contains good quality oil in Jurassic-aged carbonate reservoirs is thought to contain approximately 74 MMBO STOIIP. At present four wells are producing approximately 400 BOPD and the total production to date has been approximately 3 MMBO. In addition to the oil production, the Singleton partners utilize produced gas from the field in power generation which is sold to local users and which generates further revenue streams from the field.
The Singleton X-8x well is situated on the northern flank of the field and a 2,000 foot horizontal section was drilled and completed in the Cornbrash and Forest Marble sequences. These units, which lie above the main reservoir in the field, are presently not in production though they are known to be oil-bearing.
The Singleton X-9 well was designed to probe the main Great Oolite reservoir in the southwest flank of the field. The Operator believes that the extended-reach Singleton X-9 well broke the record for the longest 8.5" hole section drilled onshore UK. The 8.5" hole section was drilled from 1,142 feet to 9,282 feet, a length of 8,140 feet. The well has been TD'd at 9,831 feet in 6" hole.
