The Breagh gas discovery was made in 1997 by well 42/13-2 drilled by Mobil, which encountered a 450 ft gas column and a net gas pay of approximately 68 ft within sandstones of the Lower Carboniferous Scremerston Formation. The well was cored and logged but tested at sub-commercial flow rates, believed to be due to formation damage that occurred during drilling and completion of the well.
The well is designed with the principal objective of achieving a test flow rate representative of the undamaged formation, which will be important in determining the commercial viability of the discovery.
The well is being drilled by the ENSCO 85 jackup and is operated by Sterling Resources Limited, which holds a 50 percent interest in the license. EnCore will fund 30 percent of the planned gas appraisal well to earn a 15 percent equity.
