Filed:

Nov 18, 1994

Appl. No.:

8/342318

Inventors:

Alfred R. Jennings - Plano TX
Michael R. Chambers - Bedford TX

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

E21B 3700

US Classification:

166312

Abstract:

A method for improving the efficiency of horizontal wellbore cleanout of a horizontal wellbore drilled from a vertical wellbore, having a perforated liner cemented across the horizontal wellbore. The method includes running a coiled tubing into the horizontal wellbore. A first cleanup fluid is injected down the coiled tubing and a second cleanup fluid is injected down an annulus formed by the coiled tubing and the wellbore. The injection rates of the cleanup fluids in the coiled tubing and the annulus are balanced. The coiled tubing is moved back and forth over the horizontal wellbore.

Abstract:

A clip for supporting a refractory structure and/or a hanger structure. The clip can have a body with two legs connected to a top. A fastener that extends through the top can be adjusted and/or secured to fix a relative position of the clip with respect to the refractory structure and/or the hanger structure. An adjuster that extends through the top, such as a tab connected to or integrated with the top, can be used to adjust a distance, such as a vertical height, of the clip with respect to adjacent fixed structural members. The adjuster can be used to compensate for a distance change resulting from the refractory structure, the hanger structure, one or more adjacent fixed structural members, and/or any other similar structure, bending, flexing and/or otherwise deforming due to exposure of the components to a relatively high temperature.
