How do you know there is natural gas under the sea off the Isle of Man?
This part of the Manx waters has been well-documented through surveys of the sub-surface running back to the 1970s. The geology of the Irish Sea basin relates predominantly to two main periods of geological time: the Triassic and the Permian. Both periods are known to contain the appropriate rock formations and structures to provide reservoirs… [continue reading]
How have the natural gas volumes been evaluated?
The quantity of natural gas within the 2km deep reservoir is currently unknown, hence the need for further appraisal. However, the computation of in-situ natural gas is based upon 1992 2D seismic data and industry standard mapping techniques.
What kind of rocks hold the natural gas?
The natural gas is held in a reservoir rock named the Collyhurst Sandstone which can be seen in parts of Northwest England. It is a Lower Permian sandstone rock deposited by desert sands and rivers. It is referred to as a “conventional reservoir” which means it is a sandstone that holds the natural gas within… [continue reading]
What does “appraisal” mean?
Appraisal means to gather further data on an existing natural gas accumulation. This data is used to understand the potential of the accumulation and to devise a development plan.
