Large diameter shallow subsea holes of, for example, 52 inches are easily drilled and can accommodate a 48 inch subterranean separator that removes water before it enters the pipeline.

 

 

Conventional large diameter conductors are relatively weak, however when ribbing is added between two conductors they can withstand significant pressure and bending loads to improve well design.

 

 

Conductor-sharing has been used by offshore platforms for many years.  Sharing a subsea wellhead and conductor can result in significant drilling, completion and tie-back savings.

 

 

Few Operators use dual string completions because the tubing is too small to be of use.  Oilfield Innovations have a casing-sharing crossover that, like magic, provide two-for-one wells.

 

Better Well Design
Final Hole and Tubing Size versus Casing Size Combinations for Oil and Gas Wells

 

With Operators running toward onshore fracking, a new stage of offshore well design optimization must occur if it is to remain competitive.  The industry has done very little work optimising large diameters within well design.  Large diameters in offshore wells can be difficult, but offshore wells often have a competitive advantage of relatively soft surface formations without ground water isolation requirements.

 

As shown above the next stage of "offshore" well design optimization is within large hole diameters where drilling is relatively easy and large conductors can be shared between wells and still accessed through the industry standard 18 3/4 inch wellhead housing.

 

Better Subsea
Minimizing Subsea Tieback Costs by Minimising Subsea Infrastructure

 

Platforms and Subsea Tie-backs are expensive.  Cost reduction is only possible with minimal facilities platforms and subsea tiebacks with minimal subsea infrastructure.  Oilfield Innovations can help provide minimum facility mono pods and/or subsea conductor sharing that can eliminate expensive subsea infrastructure.
