PEDL 343 contains two adjacent blocks, TA09 and SE99a and covers 110 square kilometres. Block TA09 is located north of Scarborough running up the east coast and Block SE99a is located to its west.
The Cloughton-1 discovery well was drilled by Bow Valley in 1986 and encountered gas throughout the Carboniferous section. Four zones were tested, three of which were in the Carboniferous, the other within the Permian dolomitic limestone. The Cloughton-1 well test achieved rates of up to 28,000 scf/day on natural flow, however with the right completion and production optimisation techniques it is believed a well could flow at 6 mmscft/day. The gas is sweet good quality gas with >98% methane and ethane.
Log and core data indicates that porosities within the Carboniferous section are 2-9% with permeabilities of between 0.1 and 1mD.
The well was drilled crestally on the Cloughton anticline which is a NNW/SSE trending anticline with significant dip closure in all directions. Around 60m of Carboniferous net sandstone was realised with high gas saturations.
Europa has completed a preliminary audit of the gross Cloughton gas in place volumes which has resulted in a Pmean GIIP of 192 BCF and a range as detailed in the following table:
Europa regards Cloughton as a gas appraisal opportunity with the critical challenge being to obtain commercial flowrates from future production testing operations. A location for an appraisal well pad has been identified and following successful testing operations the field would be monetised by connecting to the nearby gas grid.
