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. An exemplary embodiment of the present invention will be discussed below in the context of an application using a standard 36 inch (0.9144 meter) conduit with two bores. 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 hole...

Abstract

A high pressure seal adapter for a conductor housing of a wellhead, and a method of completing a well having a conductor housing attached thereto, are disclosed. The high pressure seal adapter has a unitary body including a first circular bore extending through the unitary body. The first circular bore has a circular perimeter extending beyond a centerline of the unitary body. The unitary body further includes a second circular bore adjacent the first circular bore and extending through the unitary body. The seal adapter is configured to be installed in the conductor housing. The method includes providing such a high pressure seal adapter and installing the high pressure seal adapter in the conductor housing.

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 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 and ...
