The process involves drilling a well vertically to a certain depth and then bending the path of the drilling until it extends horizontally. Because they are longer, and the drilling process is more complex, a horizontal well is generally more expensive to drill than a vertical well, but it is expected to produce more crude oil and natural gas.
THE MATHEMATICS OF DIRECTIONAL DRILLING ... Drill a vertical section to a depth of 200m depth to reach the Kick-Off Point (KOP) and commence the Build-Up section. b. During the Build-Up section increase the angle of inclination to the vertical by 3o every 10m along the borehole until you reach 40o - …
Among above mathematical models, Tangential method is the least accurate, it assumes a straight line well path taking into consideration the inclination and azimuth at upper survey station and lower station is not accounted. Balanced Tangential Method takes into account the upper and lower survey station and approximates well path by two equal straight line segments.

Jul 06, 2011· Type II wells are made up of a vertical section, a kick- off point, a build-up section, a tangent section, a drop-off section and a hold section upto target. They are also called S Profile Wells (as they are S - shaped). Like Type I Wells, the Type II wells are drilled vertically from the surface to the kick-off point at a relatively shallow depth.

Three-dimensional visualization of a wellbore trajectory is challenging, especially for multiple and multi-lateral wells. Calculating true vertical depth (TVD), dogleg severities, and the ability to see the well path in a 3D work space is important to avoid unforeseeable issues.
Topo Map Elevation Profile - Vertical Exaggeration. An elevation profile or a topographic profile is a two-dimensional cross sectional view of the landscape. It provides a side view of the relief of the terrain along a line drawn between two locations on a topographic map.
Cross sections are plotted on special grid or cross section paper (Figure 5-5) which is printed in various grid sizes. Figure 5-5. Profile VERTICAL SECTIONS Vertical sections (Figure 5-6) are straight up and down or 90° from horizontal. There are two shots taken at the same distance or station when a vertical section is taken. Figure 5-6.
Jan 11, 2017· by Shteryo Lyomov, Phd, Dept. of Drilling, Transport and Oil & Gas Production, Mining and Geology U., Sofia, Bulgaria Directional diamond drilling (DDD) is powerful technology in the service of the mineral exploration industry. Its application plays an important role and is constantly increasing. A close look at its application reveals the most important factors […]

Dec 25, 2010· The X axis values are dates. At certain arbitrary points on the X axis (dates) I want to insert vertical lines representing events. I would like to have the vertical lines intersect as legitimate line equations and don't want to just draw over the chart in Paint. How can I make vertical lines representing events on my graph?
Vertical section definition is - a mechanical drawing showing an interior, wall thicknesses, and similar relations as if made on a vertical plane passing through the object (as a building) depicted.
A vertical drill hole (plunge = -90 deg) will plot as a vertical line on the drill section, and angle drill holes are plotted showing the appropriate inclination. The length of the line(s) which illustrate the drill hole are determined by the scale of the drill section.
For straight section the torque is normal moment multiplied with the friction factor, Eq. . This equation is valid for both 2D and 3D model . (8) T = μ rw Δ s sin α. From Eq., torque will be zero when a vertical bend (α equal to zero), while the torque will be maximum when a horizontal section (α equal to 90 degree). In case the drill ...
Intermediate casing is set through the lower vertical-return section. Drilling then continues below the intermediate casing in a vertical hole. The S-shaped well is often employed with deep wells in areas where gas troubles, saltwater flows, etc. dictate the setting of intermediate casing.
Sometimes both methods work easily. We will begin with a brief review of describing regions in the plane using vertical and horizontal cross-sections. DESCRIBING REGIONS IN THE PLANE USING VERTICAL OR HORIZONTAL CROSS-SECTIONS EXAMPLE 1: Consider the region in the plane enclosed by the graphs of $ y=2x $ and $ y= x^2 $.

Inclinational and azimuthal deviations are important figures in the oil drilling industry. Inclination and azimuth work collaboratively to create degrees for angles that are relative to the directions being dug into the ground. Inclinational deviation -- referred to as msID -- relates to vertical deviation while ...
Founded by Joel Day in 2011, Vertical Section is a Seattle based band that wraps rock and electronic influences in a dark, but dangerously accessible package. After performing a series of live shows including opening slots for CYLAB and Covenant, Vertical Section has returned to the studio to prepare a follow-up release.
The use of rotary-steerable systems (RSSs) may be required to drill an extra-long lateral section because slide drilling may not be possible with the conventional steerable motors. Medium radius horizontal wells. Medium-radius horizontal wells have build rates of 6 to 35°/100 ft, radii of 1,000 to 160 ft, and lateral sections of up to 8,000 ft.
Profile Graph. Creates a profile graph from any 3D line(s). Point Profile. Creates a profile graph from points (either points or multipoints) along a surface. For more information, see Using the Point Profile tool. Terrain Point Profile. Creates a profile graph from symbolized nodes of a terrain dataset surface.
This multi-formation vertical well drilling animation demonstrates hydraulic fracturing. Multi-Formation Vertical Well Drilling Video Animation Trascript There are many formations with multi-zone oil and gas reservoirs that are vertically drilled and stimulated using hydraulic fracturing to optimally recover these hydrocarbons.
The angle of the well bore defined by a tangent line at any point of wellbore and a vertical line is called the inclination. The vertical line is always parallel to the direction of earth's gravity. ... Free Downloadable Ebooks on Conventional Drilling, Directional Drilling, Blowout and Well Control ...
