Embodiment Construction

[0034] Embodiments of the present invention provide a separate sealing adapter that can be installed in a modified conduit housing. The seal adapter and improved casing facilitate drilling of the wellbore using standard sized drill bits and allow high pressure operation of the formed well. Exemplary embodiments of the present invention will be discussed below in application using a standard 36 inch (0.9144 meter) conduit with two boreholes. However, it is understood that suitably configured embodiments of the present invention may be used with catheters of any size and having two or more bores.

[0035] Figure 4 A perspective view of one embodiment of a high pressure sealing adapter 100 according to the present invention is shown. Figure 5 show Figure 4 A top view of the high pressure sealing adapter 100 in FIG. Figure 6 show Figure 4 and Figure 5 A side view of the high pressure seal adapter 100 in FIG.

[0036] Seal adapter 100 includes a first aperture 110 and a s...

Abstract

A high pressure seal adapter for a conductor housing of a wellhead, the high pressure seal adapter having a unitary body comprising: a first circular bore extending through said unitary body; and a second circular bore adjacent said first circular bore and extending through said unitary body; wherein said seal adapter is capable of being installed in said conductor housing. The high pressure seal adapter may further include at least one seal extending around a perimeter of said unitary body, said at least one seal contacting said conductor housing. The adapter may receive a high pressure riser in said first circular bore when said seal adapter is installed in said conductor housing, said high pressure riser having a lower surface that contacts said flange and at least one seal extending around an outside perimeter of said riser.

Description

technical field [0001] Embodiments of the present invention provide a high pressure seal adapter for connecting a distributor conduit casing to a wellhead of a well. Background technique [0002] In the drilling industry, the term "well completion" is often used to refer to the operations that prepare a wellbore to produce oil or gas from a reservoir. The term may also refer to complete wellhead assembly. The purpose of these operations is to install wellheads and other connections to optimize the flow of reservoir fluids to the wellbore, up through the production tubing and into the surface collection system. [0003] To start drilling operations, the conduit may be driven to the surface to prevent loose topsoil from collapsing into the hole while the upper portion of the borehole is being drilled. Various components can then be attached to the catheter. A single conduit for two or more completions is often used because it provides benefits such as smaller platform size ...
