Extended Reach Drilling (ERD) is directional drilling of very long non-vertical wells. The aims of ERD are: a) to reach a larger area from one surface drilling location, and b) to keep a well in a reservoir for a longer distance in order to maximize its productivity and drainage capability.
Directional drilling (or slant drilling) is the practice of drilling non-vertical bores. It can be broken down into four main groups: oilfield directional drilling, utility installation directional drilling, directional boring (horizontal directional drilling - HDD), and surface in seam (SIS), which horizontally intersects a vertical bore ...
The Lax–Friedrichs method, named after Peter Lax and Kurt O. Friedrichs, is a numerical method for the solution of hyperbolic partial differential equations based on finite differences. The method can be described as the FTCS (forward in time, centered in space) scheme with a numerical dissipation term of 1/2.
A structure map, looking downward, generated by contour map software for an 8,500-ft-deep gas and oil reservoir in the Erath Field, Erath, Louisiana. The left-to-right gap near the top indicates a fault line between the blue and green contour lines and the purple, red, and yellow lines. The thin red circular line in the middle indicates the top ...
The shale drilling techniques that led to a boom in oil and gas output have also spurred the development of geothermal, which in theory could provide a stable source of power equal to the demand ...
Mud pump (#4) is a reciprocal type of pump used to circulate drilling fluid through the system. Mud tank (#1) is often called mud pits and stores drilling fluid until it is required down the wellbore. Setback (#17) is a part of the drill floor (#21) where the stands of drill pipe are stood upright. It is typically made of a metal frame ...
U.S. President-elect Donald Trump said on Tuesday he will direct his Justice Department to "vigorously pursue" the death penalty to protect Americans from "violent rapists, murderers, and monsters ...
