Rotary table (#20) rotates, along with its constituent parts, the kelly and kelly bushing, the drill string and the attached tools and bit. Shale shaker (#2) separates drill cuttings from the drilling fluid before it is pumped back down the wellbore. Stand (#16) is a section of 2 or 3 joints of drill pipe connected and stood upright in the ...
This component sits in the upper portion of the wellhead, within the tubing head flange and serves as the main support for the production tubing. The tubing hanger may be manufactured with rubber or polymer sealing rings to isolate the tubing from the annulus. The tubing hanger is secured within the tubing head flange with lag bolts.
API 6A, 20th Edition, October 2010; Specification for Wellhead and Christmas Tree Equipment; ISO 10423:2009 Wellhead and Christmas Tree Equipment; In general well heads are five nominal ratings of wellheads: 2, 3, 5, 10 and 15 (×1000) psi working pressure. They have an operating temperature range of −50 to +250 degrees Fahrenheit. They are ...
In oil drilling, a casing head [1] is a simple metal flange welded or screwed onto the top of the conductor pipe (also known as drive-pipe) or the casing and forms part of the wellhead system for the well.
Many new systems in recent years have been introduced for well completion. Multiple packer systems with frac ports or port collars in an all-in-one system have cut completion costs and improved production, especially in the case of horizontal wells. These new systems allow casing to run into the lateral zone equipped with proper packer/frac ...
