Directional Drilling Pdf Directional drilling is a broad term used to describe any boring that doesn’t go in a straight line vertically down. in fact, even in a vertical well, it might be necessary to deviate to avoid a geological formation or a previous stuck pipe, then return to the original path. This document discusses well profiles, directional drilling assemblies, measurement tools, different directional well types like build up and drop off wells, and applications like sidetracking, fault drilling and extended reach wells.
Directional Drilling Pdf Pdf Acceleration Curvature Introduction introduction to directional drilling d irectional drilling is a special drilling operation used when a well is intentionally curved to reach a bottom location. the well follows an angular line from the surface to the target. these wells are known as deviated wells and are made for several reasons, such as:. Unlike traditional vertical drilling, which drills straight down into the earth, directional drilling allows engineers to drill at various angles, including horizontal or inclined paths, to access and extract oil or gas reserves located beneath the surface. This document discusses directional drilling techniques and their applications. it begins by defining directional drilling as deflecting a wellbore in a specified direction to reach a target below the surface. Directional drilling is a drilling technique that’s typically used in the oil and construction industries. oil companies use it to access underground oil reserves, and construction companies use it for a range of purposes. vertical drilling involves drilling directly downwards.
Part 2 Directional Drilling Pdf Drilling Mechanical Engineering This document discusses directional drilling techniques and their applications. it begins by defining directional drilling as deflecting a wellbore in a specified direction to reach a target below the surface. Directional drilling is a drilling technique that’s typically used in the oil and construction industries. oil companies use it to access underground oil reserves, and construction companies use it for a range of purposes. vertical drilling involves drilling directly downwards. This content provides an overview of a training course focused on the fundamentals of directional drilling. key topics include well planning considerations, deflection methods, bottom hole assembly (bha) selection, hydraulics, and torque and drag management. Directional drilling is the art and science of deviating a well bore along a planned course to a subsurface target whose location is a given lateral distance and direction from the vertical. it involves the intentional deflection of a wellbore in a specific direction in order to reach a predetermined objective below the surface of the earth. It defines directional drilling, describes its applications and history, and explains methods for deviating well bores including rotary assemblies, jetting, whipstocks, and dynadrill. directional drilling is used to plan and deviate well bores to hit subsurface targets at planned locations.
