  • Patent number: 11608464
    Abstract: A scale inhibitor includes an amount of hydroxyethylidene diphosphonic acid (HEDP), and an amount of hydroxyapatite. The amounts are combined to form a composition that is long lasting, high activity and completely dissolvable. The composition has a preferred particle size of less than 200 nm. Dicalcium phosphate, tricalcium phosphate, bone and/or bone ash may be used in place of hydroxyapatite.

  • Patent number: 11365343
    Abstract: A solid scale inhibitor for use in fracking operations to inhibit scale build up, includes a powdered composition having a salt component and an acid component; the powdered composition is 100% dissolvable; and the acid component increases the dissolution rate associated with the salt component, thereby preventing the salt component from contributing to scaling formation in one or more production lines within a fracking operation. While both the salt and the acid in the present invention inhibit scale formation on their own, the acid (HEDP in the preferred embodiment) dissolves quickly, while the salt (HA in the preferred embodiment) dissolves very slowly; by combining the two, the dissolution rate of the acid is slowed and the dissolution rate of the salt is increased. Thus providing for an effective long term solid scale inhibitor.

  • Patent number: 8993492
    Abstract: A crosslinking composition for hydrocarbon gels containing phosphate ester gelling agents comprising a modified imidazoline or pyrimidine including an alkyl group (or unsaturated carbon chain) or of 10 to 22 carbon atoms, a polyamine, and ferric sulfate. The method of making the crosslinking agent features adding the polyamine after reaction of the other ingredients; unique gels formed with the crosslinking agent are particularly effective for LNG at very cold temperatures.

  • Patent number: 8707978
    Abstract: Where the loss of volatile organics during storage of high gravity oil is minimized by forming a flowable or pumpable gel in the high gravity oil, (and/or condensates and distillates), as they are introduced to a storage vessel, the gel is broken by the addition of a small amount of an amine/formaldehyde reaction product, which may be either a triazine or a mixture of non-triazine reaction products. The previously gelled hydrocarbon may then by more readily moved by draining or pumping into a pipeline.

  • Publication number: 20130025857
    Abstract: Volatile organics in newly produced oil and gas, and/or condensates and distillates from produced oil and gas, are treated to depress vapor pressure to preserve light hydrocarbons in them when they are in storage vessels. The loss of volatile organics during storage of high gravity oil is minimized by forming a flowable or pumpable gel in the high gravity oil, (and/or condensates and distillates), as they are introduced to a storage vessel. The gel-former may comprise a phosphate ester of one or more low molecular weight alcohols, and a crosslinker including a source of iron or aluminum. Although the gels are flowable and pumpable, they can be broken for transportation from the production site or at another desirable time, returning the hydrocarbon product to its original properties.
