Moving oil and gas from ultradeep offshore reservoirs to process and market

 

There are only two options: shuttle tankers or pipelines.

Shuttle tankers require services from an on site, one million barrels or larger, Floating Storage Unit (FSU) or Floating Production, Storage and Offload facility (FPSO).  The option is very costly with a potentially huge environmental impact.

A pipeline requires ancillary services, either from a smaller floating facility on site or from shore through auxiliary pipelines. The environmental impact is minimal, especially with services from shore.

Pipelines are the preferred solution wherever workable. Shuttle tankers are the solution where a pipeline is not workable.

Pipelines are the only means of transportation used from the Gulf of Mexico’s operational deepwater fields to the US mainland.

Gulf of Mexico’s ultradeep oil and gas operations are limited by industry capabilities. Two major factors dominate industry limitations:

· Distance, which affects pipe size: the longer the pipeline the larger its diameter to counteract pressure loss.

· Depth, which impacts weight: the deeper the pipeline the thicker its wall to withstand outside pressure; additionally deep means more vertical linear feet of pipe hanging from the facility.

These factors combine to create an exponential growth in required pipelay facility capabilities.

Specifically, laying a pipeline from 5,000 ft waterdepth 60 miles offshore to a 12,000 ft waterdepth 200 miles from shore means the weight of the pipeline hanging from the construction facility could increase tenfold.  

This quantum leap makes today’s  technologies obsolete and scaling-up of existing huge facilities impossible.  The process must be re-thought, re-engineered and based upon new and different operating models.

DeepGulf has developed and patented new technologies and solutions based on a new model developed from the ground up. The technologies are collectively known as J-Flex and offer critical technical and financial advantages.

DeepGulf opens for the first time the Ultradeep Offshore Frontier to pipeline exploitation, by enabling  installation of large 24 inch pipelines in 12,000 feet of water.
