Filed:

Jul 13, 2001

Appl. No.:

09/904735

Inventors:

Robert P. Badrak - Sugar Land TX
Robert J. Coon - Missouri City TX
Roddie R. Smith - Cypress TX
Patrick G. Mcguire - Cypress TX

Assignee:

Weatherford/Lamb, Inc. - Houston TX

International Classification:

E21B 4310

US Classification:

166381, 166207, 166291

Abstract:

The present invention provides a liner hanger and a method of hanging a liner in a wellbore. In one aspect, a process for setting a liner in a wellbore is provided in which a tubular having a slip formed on an outer diameter of the tubular at a first location and a preformed bypass for circulating a fluid disposed at a second location is set and expanded into substantial contact with an inner diameter of the wellbore, a casing, or another liner. In another aspect, a process for setting a liner in a wellbore is provided in which a tubular having a slip formed on an outer diameter of the tubular at a first location is placed in the wellbore, a bypass for circulating a fluid is formed downhole, the liner is set and expanded into substantial contact with an inner diameter of the wellbore, a casing, or another liner. In yet another aspect, a process for creating a liner top seal is provided in which the liner is set by expanding a protrusion in an upper end of a tubular into substantial contact with an inner diameter of the wellbore, and the upper end of the tubular is then reformed and expanded into substantial contact with the inner diameter of the wellbore.

Abstract:

Hydrocarbons are recovered from subterranean formations by waterflooding. The method comprises passing an aqueous displacement fluid via an injection well through a porous and permeable sandstone formation to release oil and recovering said released oil from a production well spaced from said injection well, wherein (a) the sandstone formation comprises at least one mineral having a negative zeta potential under the formation conditions; (b) oil and connate water are present in the pores of the formation; and (c) the fraction of the divalent cation content of the said aqueous displacement fluid to the divalent cation content of said connate water is less than 1.
