measuring circuit into the geologic medium varies with the electrode spacing, logs of the various arrays (short-and long-normal and lateral) can be analyzed collectively to evaluate the effects of bed thickness, borehole fluids, drilling mudcake, variations in fluids, and permeabilities of strata at various distances from the borehole. TheBorehole drilling is the process of punching a hole in the ground to extract groundwater. Everything that happens at this point is in reference and under the guidance of the surveyor’s report. The drilling exercise is usually completed by installing casings and “well screens” to keep the borehole from caving in yet allowing water to ...So, in 2013 Consol Energy proposed to produce natural gas from the Marcellus Shale by drilling 47 horizontal wells from 6 well pads located on adjacent lands.
