Method For Enhancing The Compatibility Of A Zinc-Brine Completion Fluid With A Fracturing Fluid

View page
US Patent:
6138755, Oct 31, 2000
Filed:
May 19, 1998
Appl. No.:
9/080993
Inventors:
Rosa Swartwout - Sedona AZ
Assignee:
Tetra Technologies, Inc. - The Woodlands TX
International Classification:
E21B 4326
US Classification:
1662501
Abstract:
In a method for enhancing the compatibility of a zinc-brine completion fluid with a fracturing fluid, test samples of selected completion fluids are combined with test samples of selected fracturing fluids to form an admixture. The parameters of incompatibility between the completion fluid and the fracturing fluid are analyzed and identified. The parameters or indicia of incompatibility identified can be precipitation, emulsification and/or an increase in viscosity. The zinc brine completion fluid is then blended with additives to remove these parameters of incompatibility. The additives can be selected from a group comprising hydrochloric acid, hydrobromic acid, acetate salts, citrate salts, and surfactants. At the well site, the altered zinc brine completion fluid is pumped in to displace drilling fluids in the wellbore before pumping in fracturing fluid. Additional altered brine completion can follow the fracturing fluid into the wellbore.

Gas Leak Estimation

View page
US Patent:
20230126546, Apr 27, 2023
Filed:
Oct 12, 2022
Appl. No.:
17/964398
Inventors:
- Houston TX, US
Sangeeta Nundy - Denver CO, US
Bhasker Rao Keely - Bangalore, IN
Rosa Swartwout - Tucson AZ, US
International Classification:
G01M 3/38
Abstract:
Data characterizing a first set of locations of a plurality of sensors at an industrial site is received. Gas concentration, wind velocity at the industrial site, and an identified leakage area at the industrial site are detected by the plurality of sensors. Locations and leakage rates of one or more leakage sources is determined in the identified leakage area by a predictive dispersion model. The predictive dispersion model is configured to receive the wind velocity at the industrial site and the locations and leakage rates of the one or more potential leakage sources as input and generate the set of estimated gas concentration as output. A comparative metric based on the set of estimated gas concentrations is compared to the detected gas concentrations. The selected location and leakage rates of the potential leakage sources in a current iteration of the iterative determination are provided.

Appl. No.:
15/358750
Inventors:
- Houston TX, US
ROSA SWARTWOUT - Spring TX, US
ANDREW DEFREES - Cypress TX, US
MOCTESUMA R. TREVINO - Houston TX, US
MAHIR DAIFALLA ALRASHDAN - Euless TX, US

JENNIFER ROBERTSON - Houston TX, US
Assignee:
BAKER HUGHES INCORPORATED - Houston TX
International Classification:
C09K 8/05
C09K 8/42
C09K 8/52
Abstract:
High density brine compositions may be formulated including water and at least one rare earth nitrate salt, where the at least one rare earth salt is present in an amount effective for the high density brine composition to have a density in the range of about 8.5 to about 21 pounds per gallon (about 1020 to about 2500 kg/m). Suitable rare earth nitrate salts include, but are not necessarily limited to, lanthanum nitrate (La(NO)), cerium nitrate (Ce(NO)), scandium nitrate, and/or yttrium nitrate. Alkaline earth metal salts such as, but not limited to, calcium bromide (CaBr), and alkali metal salts and metal salts may also be used with the rare earth nitrate salt(s). In one non-limiting embodiment the high density brines have an absence of zinc and cesium salts. These high density brine compositions may be suitably used for completion fluids in hydrocarbon recovery operations.
