Description
In the drilling industry, communication is essential between the company and its Foreman, contractors, consultants, field operators and all personnel. To move ahead making the right choices and/or wrong choices has to do with experience - one can only see so far down the hole and therefore relying on the operations expertise is the best option.
Typically, Engineers build a well from the bottom up - after checking with the Production, Completion and Reservoir Engineers' measurements to determine the size pipe to use and after examining logs, geological information, depleted zones, target zones and unconsolidated formations they determine what is needed to begin drilling the well. Faults can be an enemy or a friend to the Engineer. Sandstone is similar to sponge, it has permeability; Shale is impermeable and no fluids are allowed. If drilling in shale a fault with no seal, it can be good and bad. The pressure inside the hole determines the reservoir of oil. The pore pressure is the pressure of fluids with the pores of a reservoir. Abnormal pressure is when impermeable rocks, such as shale, are compacted. The pore fluids cannot always escape and must support the total overlying rock column, this leads to anomalies of high formation pressures. Overburden is the weight of overlying rock.
Hydrostatic pressure refers to the pressure exerted by the drilling fluid in the wellbore. The Wireline operations are the lowering of mechanical tools, in the well.
