Methods Of Treating Flowback Water

View page
US Patent:
20100307753, Dec 9, 2010
Filed:
Jun 4, 2010
Appl. No.:
12/794550
Inventors:
Paul Rey - Coraopolis PA, US
Susan Rey - Coraopolis PA, US
David Grottenthaler - McDonald PA, US
Assignee:
KROFF WELL SERVICES, INC. - Pittsburgh PA
THE NATIONAL COLLOID COMPANY - Steubenville OH
International Classification:
E21B 43/16
C09K 8/62
US Classification:
1663051, 507200
Abstract:
Methods of treating flowback water from a subterranean formation penetrated by a well bore are provided, comprising: (a) providing remediated flowback water having a ferrous iron (Fe) ion concentration of less than about 100 milligrams of ferrous iron ion per liter of flowback water, a barium ion (Ba) concentration of less than about 500 milligrams of barium ion per liter of flowback water, and a calcium ion (Ca) concentration of at least about 1,000 milligrams of calcium ion per liter of remediated flowback water; and (b) treating the flowback water with: (i) at least one friction reducing agent; and (ii) at least one scale formation inhibiting agent and/or at least one iron precipitation control agent to provide treated flowback water which can be reused as fracturing fluid in a well drilling operation.

US Patent:
20100311623, Dec 9, 2010
Filed:
Jun 4, 2010
Appl. No.:
12/794514
Inventors:
Paul Rey - Coraopolis PA, US
Susan Rey - Coraopolis PA, US
Michael John Seyman - Warren OH, US
David Grottenthaler - McDonald PA, US
Assignee:
Kroff Well Services, Inc. - Pittsburgh PA
The National Colloid Company - Steubenville OH
Superior Well Services, Inc. - Indiana PA
International Classification:
C02F 5/10
C09K 8/62
US Classification:
507259, 252180, 252181, 507256
Abstract:
Fluid treatment systems and compositions are provided including (a) at least one material including (1) at least one carboxylic acid functional group and (2) at least one sulfur-containing group selected from the group consisting of sulfonyl functional groups, sulfonate functional groups and mixtures thereof; and (b) at least one scale control agent. The fluid treatment systems and compositions can be used to treat aqueous systems, for example as fracturing fluids for treating aqueous compositions found in subterranean formations. Methods for inhibiting formation and/or precipitation of calcium salts in an aqueous composition using the fluid treatment systems or compositions also are provided.
