Well Completions In Weakly Consolidated Formations
US Patent:
5685374, Nov 11, 1997
Filed:
Feb 14, 1996
Appl. No.:
8/601192
Inventors:
Joseph H. Schmidt - Anchorage AK
Frank E. Bergren - Anchorage AK
Michael L. Bill - Anchorage AK

Assignee:
Atlantic Richfield Company - Los Angeles CA
International Classification:
E21B 4300
US Classification:
166369
Abstract:
Weakly consolidated hydrocarbon fluid bearing earth formation zones having a cohesive strength of about 500 psi or less are produced by completing a well penetrating the zone and initiating production of solids laden fluid from the zone through the well to generate a near wellbore cavity. Production of solids laden fluid is continued until the cavity grows to a point wherein the fluid velocity across the cavity face decreases to a value below the solids particulate transport velocity wherein continued production of fluid will result in a very low or negligible rate of production of solids particulates. Solids particulates are separated from the produced mixture at the surface, the solids are treated to reduce the particle size and reinjected in a slurry into a disposal well for disposal in a hydraulically fractured or disaggregated formation zone remote from the production zone. Cavity growth and production may be carried out by throttling a free flowing well or by artificial lift, preferably utilizing power fluid and a hydraulic jet pump or gas lift techniques.
Slurry Injection Into Disaggregated Earth Formations
US Patent:
5387737, Feb 7, 1995
Filed:
Apr 6, 1993
Appl. No.:
8/043323
Inventors:
Joseph H. Schmidt - Anchorage AK

Assignee:
Atlantic Richfield Company - Los Angeles CA
International Classification:
A62D 300, B09B 300
US Classification:
588250
Abstract:
Slurries of particulate solids wastes are injected into a disaggregated earth formation through an injection well by predetermining the formation to have a compressive stress in a range of about 300 psi to 2500 psi, a porosity of at least about twenty percent (20%) and disposed between overburden and underburden layers which have a substantially lower permeability than the disposal zone. The disposal zone is disaggregated or "liquified" by injecting substantially solids-free liquid followed by injection of the solids-laden slurry.
