v: to verify or witness, by a designated company official, the signature of the signing company officer and the affixing of the official company or corporation seal. The title of the company official executing the instrument and the title of the company official attesting it should appear under the signatures.

n: 1. in directional drilling, the direction of the wellbore or of the face of a deflection tool in degrees (0-359") clockwise from true north. 2. an arc of the horizon measured between a fixed point (such as true north) and the vertical circle passing through the centre of an object.

n: Reflecting the direction of wellbore deflection.

an attachment strap to affix cable or capillary tube to the outside of the tubing.

n: an effect that occurs when certain shale zones are penetrated by the wellbore and the pressure exerted by the drilling mud exceeds the pressure exerted by the shale. The pressure differential causes the borehole to flex, or balloon, and the borehole no longer behaves as a fixed, rigid cylinder.

n: a section of the lining of a brake band shaped to conform to the curvature of the band and attached to it with countersunk screws. See brake band.

n: The heatproof, abrasion proof, and high friction coefficient blocklike component part. Made by material pressure stencil or plait pressure stenci. Fixed in the inner surface with head screw. The friction produced by contact of brake drum when working.

n: the part of the brake that presses on the brake drum. On the drawworks, the circular series of brake blocks are bolted to the brake bands with counter- sunk brass bolts;the lining is the frictional, or gripping, element of a mechanical brake.

n: Refers to the lining of brake staple which is consisted of a set of brake blocks. Fixed in the inner surface of brake staple with head aluminium screw. Brake lining stops when the surface of brake holds the brake drum.

n: the curve assumed by a perfectly flexible line hanging under its own weight between two fixed points. A suspension bridge is an example of a catenary structure;an anchor chain is a catenary.

n: a device with an orifice installed in a line to restrict the flow of fluids. Surface chokes are part of the Christmas tree on a well and contain a choke nipple, or bean. with a small-diameter bore that serves to restrict the flow. Chokes are also used to control the rate of flow of the drilling mud out of the hole when the well is closed in with the blow-out preventer and a kick is being circulated out of the hole. See adjustable choke. bottomhole choke. positive choke.

n: A device incorporating an orifice that is used to control fluid flow rate or downstream system pressure. Chokes are available in several configurations for both fixed and adjustable modes of operation. Adjustable chokes enable the fluid flow and pressure

a device used to create a controlled pressure drop and allow some expansion of the gas. A choke holds a back pressure on the well fluids, controlling the expansion rate of the gas. It is useful for optimizing natural gas lift in oil wells with sufficient
مسدود کردن


n: a device placed in a choke line that regulates the flow through the choke. Flow depends on the size of the opening in the bean;the larger the opening. the greater the flow.

a flow tube for a fixed bean-type choke.

n: a visual test made against fixed standards to determine the colour of a petroleum or other type of product.
