  • Patent number: 5871049
    Abstract: The present invention provides a method of treating a wellbore penetrating a subterranean formation with a treatment fluid whereby fine particulate flowback is reduced or prevented. The method includes the steps of providing a fluid suspension including a mixture of a particulate coated with a tackifying compound, pumping the suspension into a subterranean formation and depositing the mixture within the formation whereby the tackifying compound retards movement of at least a portion of any fine particulate within the formation upon flow of fluids from the subterranean formation through the wellbore. Alternatively, the tackifying compound may be introduced into a subterranean formation in a diluent containing solution to deposit upon previously introduced particulates to retard movement of such particulates and any fines subject to flow with production of fluids from the subterranean formation.
    Type: Grant

  • Patent number: 5833000
    Abstract: The present invention provides a method of treating a subterranean formation with a particulate laden fluid whereby particulate flowback is reduced or prevented. The method includes the steps of providing a fluid suspension including a mixture of a particulate upon which at least a partial coating of a tackifying compound is formed as a result of admixture of the tackifying compound therewith, pumping the suspension into a subterranean formation and depositing the mixture within the formation whereby the tackifying compound retards movement of at least a portion of the particulate within the formation upon flow of fluids from the subterranean formation.

  • Patent number: 5420174
    Abstract: Methods and compositions are provided for producing a curable resin coated proppant and a crosslinked aqueous gel carrier fluid system. The resin coated proppant and crosslinked aqueous gel carrier fluid system provided may be controllable thinned or "broken" by the addition of a quantity of oxidizing breaker similar to the quantity of oxidizing breaker sufficient to break the carrier fluid in traditional non-resin coated proppant and crosslinked aqueous gel carrier fluid system. A resole resin is the film forming material use to coat the proppant.

  • Patent number: 5368102
    Abstract: A well treating composition comprising: a gelled carrier; a particulate material; an epoxy resin system including at least one epoxy resin; and a finely-divided hardening agent which, when dissolved, is operable for hardening the epoxy resin. The finely-divided hardening agent is dispersed in the epoxy resin system. A method of treating a subterranean zone located in a well comprising the steps of: (a) preparing the above-described treating composition; (b) injecting the treating composition into the well such that the treating composition is placed in the subterranean zone; and (c) maintaining the finely-divided hardening agent under conditions such that, prior to injecting the treating composition into the well, the finely-divided hardening agent does not substantially dissolve.
