Method For Fracturing A Formation To Control Sand Production
US Patent:
5497658, Mar 12, 1996
Filed:
Mar 25, 1994
Appl. No.:
8/218007
Inventors:
Paul A. Fletcher - Richardson TX

Assignee:
Atlantic Richfield Company - Los Angeles CA
International Classification:
E21B 4900, E21B 4326
US Classification:
73151
Abstract:
A method for determining the minimum length for a fracture in a fluid-producing formation to control the production of sand therefrom wherein a plurality of critical drawdown pressures are calculated from known formation data which correspond to a plurality of different, estimated respective fracture lengths. Once the critical drawdown pressures for the reservoir are correlated with their corresponding fracture lengths, a critical drawdown curve for that particular reservoir is established. Additional sets of curves are generated from known data which when overlaid with the critical drawdown pressure curve allows a minimum length of fracture to be selected which will produce the formation at a given rate at a prescribed drawdown pressure without producing any substantial amounts of sand from the formation.

International Classification:
G06G 7/48, E21B 47/01, G01V 1/40, E21B 47/00
US Classification:
703 9, 16625001, 702 6, 703 10
Abstract:
A method for predicting the on-set of sand production or critical drawdown pressure (CDP) in high flow rate gas wells. The method describes the perforation and open-hole cavity stability incorporating both rock and fluid mechanics fundamentals. The pore pressure gradient is calculated using the non-Darcy gas flow equation and coupled with the stress-state for a perfectly Mohr-Coulomb material. Sand production is assumed to initiate when the drawdown pressure condition induces tensile stresses across the cavity face. Both spherical and cylindrical models are presented. The spherical model is suitable for cased and perforated applications while the cylindrical model is used for a horizontal open-hole completion.
Method For Strengthening A Subterranean Formation
US Patent:
6273192, Aug 14, 2001
Filed:
Mar 29, 2000
Appl. No.:
9/537153
Inventors:

Gangerico G. Ramos - Allen TX
Assignee:
Atlantic Richfield Company - Chicago IL
International Classification:
E21B 3313
US Classification:
166294
Abstract:
A method for strengthening a subterranean formation by injecting an aqueous gellable composition containing a cross-linkable polymer into the subterranean formation through a wellbore to increase the strength of the subterranean formation while retaining the ability of the subterranean formation to produce fluids.
