Typical logging sondes use a Cesium-137 source, which emits gamma rays of 0.66MeV. At this high energy level, Compton scattering dominates. The average electron density in the volume of formation probed by the tool controls the …The Bakken Formation consists of a lower shale member, a middle sandstone member, and an upper shale member. The shales are organic-rich and of marine origin. They are rich source rocks for oil and natural gas. All three members of the Bakken Formation have been known to yield oil and natural gas.

OtherShale gas production and utilization have dramatically transformed the North American and global natural gas landscape. Shale formations and their associated hydrocarbons have been found to be internationally abundant based on US EIA studies, although extraction largely depends on availability of massive fracturing equipment.

Shale. Shale is a very fine-grained, clastic sedimentary rock which is made up mostly of clay (defined as particles smaller than 1/256 mm) and which is fissile (tending to break along natural laminations, or planes of weakness, that are less than 1 cm thick). Generally, shale occurs in thin layers or beds and represent low-energy environments ...
