1 The Bowland-Hodder shale gas play (or Bowland-Hodder shales) is the term used in this report for an amalgamation of shales of Visean to early Namurian age that includes the Bowland Shale Formation (and its equivalents) together with older shales which equate to the Hodder Mudstone Formation.irky Misperton 1 drilled a complete Bowland-Hodder unit thickness of 4598 ft (1401 m). The organic-rich upper part of the Bowland-Hodder unit is typically up to c.500 ft (150 m) thick, but locally reaches 2900 ft (890 m).
Shale is a sedimentary rock composed of very fine clay particles. Clay forms from the decomposition of the mineral feldspar. Other minerals present in shale are quartz, mica, pyrite, and organic matter. Shale forms in very deep ocean water, lagoons, lakes and swamps where the water is still enough to allow the extremely fine clay and silt particles to settle to the floor. Geologists estimate that shale represents almost Â¾ of the sedimentary rock on the Earthâs crust. Geologists are specific about the definition of the rock called âshale.â Shale is composed of clay particles that are less than 0.004 mm in size. Relation to Mining Typically, common clays and shales are dug from open pits, and these pits must be near the processing plants to minimize production costs.
