  • Sand consolidation with flexible gel system
    Patent number: 6450260
    Abstract: Herein is described a method of consolidating a subterranean formation or repairing a gravel pack, comprising (i) providing a consolidating fluid, wherein the consolidating fluid comprises a gel component and a gel-forming agent; and (ii) injecting the consolidating fluid into the formation or gravel pack, under conditions wherein the gel component forms a flexible gel, thereby consolidating the formation.

  • Optimum perforation design and technique to minimize sand intrusion
    Patent number: 6283214
    Abstract: The present Invention relates to novel devices and methods to minimize the production of sand in subterranean environments; in particular, in poorly consolidated formations, sand is often co-produced along with the desired fluid (e.g., oil); sand production is undesirable, hence in the present Invention, elliptically shaped perforations of a particular orientation are created in the casing (or directly into the formation in the case of an uncased wellbore) that lines wellbore drilled through the formation, to improve near-wellbore stability of the formation, hence minimizing sand intrusion.
