GE Surface Specialty Wellheads Broschüre

GE Oil & Gas

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 specific 

criteria supplied by our clients.
Platforms with available slots are often seen as the first 

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 effect on field 

production economics.
Additional benefits can be derived by reducing the overall 

height and size of new structures or by eliminating the need 

for additional structures to develop existing fields.

 

• 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”.
