Specialty Wellheads

Close-Proximity Wellhead (CPW) Systems

Close-proximity wellhead systems enable two or more

wellbores to be placed within a single conductor or caisson

with production through adjacent independent wellhead

systems. Each CPW system is customized to meet specic

criteria supplied by our clients.

Platforms with available slots are often seen as the rst

candidates for incorporating a CPW. When combined with

3D seismic, extended-reach drilling, horizontal drilling and

multilateral completions, a few well-placed additional

completions can have a dramatic positive eect on eld

production economics.

Additional benets can be derived by reducing the overall

height and size of new structures or by eliminating the need

for additional structures to develop existing elds.

Features —

• When compared to systems with multiple strings of casing

or tubing suspended in a single wellhead component,

completely independent adjacent wellhead systems:

– Allow the use of smaller BOP stacks,

– Eliminate communication between wellbores, and

– Allow easier workover or repair.

• Whenever possible, minimum clearance wellhead

equipment connector technology is included.

• Conventional or multi-bowl wellhead options are available.

• Pressure ratings up to 15,000 psi can be accommodated.

• Field-proven designs have been used on projects involving

2, 3, 5, 6, 11, and 12 close proximity wells with inside

casing and conductor strings ranging from 13-3/8” to 120”.
