Filed:

Oct 8, 2020

Appl. No.:

17/065758

Inventors:

- Houston TX, US
John MAYOR - Cypress TX, US
D.V. Satyanarayana GUPTA - The Woodlands TX, US
Minh Quoc VO - Spring TX, US

International Classification:

E21B 43/26
C09K 8/68

Abstract:

A fluid for use in hydraulic fracturing contains underivatized guar or a guar gum derivative as viscosifying or gelling polymer, a crosslinking agent, carbon dioxide as foaming agent and urea and, optionally, a bifunctional organic compound containing at least one hydroxyl group and at least one quaternary group and, optionally, a non-gaseous foaming agent. The fluid may be characterized by a low pH such as a pH than or equal to 3.0 and less than or equal to 5.0.

Minh Vo - Houston TX, US

International Classification:

C09K 8/68

C09K 8/035
C09K 8/72

Abstract:

A fracturing fluid containing a hydratable viscosifying polymer and a zirconium acetylacetonate crosslinker provides a green alternative to conventional systems. The zirconium aceylacetonate is dissolved in benzyl alcohol or in a mixture of benzyl alcohol and 2,2-dimethyl-1,3-dioxolan-4(yl)-methanol. The pH of the fracturing fluid may be between from about 3.5 to about 11.5. The fracturing fluid may contain an acidic buffering agent or a basic buffering agent. The fracturing fluid may be pumped into a well in order to initiate or enlarge a fracture within a subterranean formation penetrated by the well.

International Classification:

C09K 8/68
C09K 8/60
E21B 43/26
C09K 8/88

Abstract:

A gel composition for use in subterranean formations is disclosed. The composition can comprise a base fluid, a cross-linkable polymer that is soluble in the base fluid, a nonionic surfactant and a cross-linking agent. The gel composition has improved crosslinked stability. The gel composition can be injected into the subterranean formation as a fracturing fluid and allowed to penetrate the formation. Preferably, the gel composition effectively blocks the water-bearing regions while the oil or gas producing regions are left unblocked so that the oil or gas can be recovered.
