CONTRACTIBLE TUBING FOR PRODUCTION (17657441)

Inventor Tolu Ogundare

Brief explanation

The abstract describes a type of tubing that can contract or shrink in size when exposed to a fluid. The tubing consists of an outer pipe, an inner pipe, and a layer in between called the intermediate layer. The intermediate layer contains a material called elastomer, which can expand when in contact with the fluid. 

The method for using this contracting tubing involves opening a passage in the tubing to allow the fluid to reach the intermediate layer. When the elastomer comes into contact with the fluid, it swells or expands. This expansion exerts a force on the inner pipe, causing it to contract or become smaller in diameter.

Before the fluid contact, the inner pipe has a certain diameter, referred to as the first inner diameter. However, after the fluid contact and the swelling of the elastomer, the inner pipe's diameter becomes smaller, referred to as the second inner diameter.

Abstract

A contracting tubing includes an outer pipe, an inner pipe, and an intermediate layer positioned between the outer pipe and the inner pipe. The intermediate layer includes an elastomer that is swellable in a fluid. A method for using the contracting tubing includes opening a fluid passage in the contracting tubing to the intermediate layer to contact the intermediate layer with a fluid and swell the elastomer. The swelling of the elastomer applies a force on the inner pipe and contracts the inner pipe, such that the inner pipe has a first inner diameter prior to contacting the intermediate layer with the fluid and a second inner diameter smaller than the first inner diameter after contacting the intermediate layer with the fluid.

Inventor Karla Patricia Olvera Carranza

Brief explanation

This abstract describes a method for developing hydrocarbon reservoirs. It involves analyzing fracture data to create a 2D fracture model, which shows the locations of fractures in the reservoir.
