Patent number: 10370951Abstract: A method of performing a squeeze treatment comprises pumping a treatment fluid under pressure through a wellbore into a subterranean formation, wherein the treatment fluid includes a hydrogen sulfide scavenging compound that adsorbs onto the subterranean formation in a region around the wellbore. Production fluids are then allowed to flow from the subterranean formation into the wellbore, wherein the production fluids contact the adsorbed hydrogen sulfide scavenging compound as the production fluids flow through the region around the wellbore, and wherein the production fluids contain hydrogen sulfide that reacts with the hydrogen sulfide scavenging compound to reduce an amount of hydrogen sulfide in the production fluids before the production fluids flow into the wellbore.Type: GrantFiled: February 19, 2018Date of Patent: August 6, 2019Assignee: Ecolab USA Inc.Inventors: Joseph Paul Bailey, Aaron D. Martinez, Erick J. Acosta, Ravindranath Mukkamala, Maximilian A. Silvestri, Jose M. Macias

Patent number: 9630139Abstract: Functionalized alpha-hydroxy alkyl ethers have been found to perform as non (or anti-) scaling hydrogen sulfide scavengers. A method of scavenging hydrogen sulfide includes contacting a fluid containing hydrogen sulfide with a treatment fluid including a functionalized alpha-hydroxy alkyl ether. Accordingly, the alpha-hydroxy alkyl ether reacts with the hydrogen sulfide to reduce the amount of hydrogen sulfide in the fluid. The functionalized alpha-hydroxy alkyl ether is functionalized with a phosphate group, phosphonate group, sulfate group, or sulfonate group. A broad range of alpha-hydroxy alkyl ethers are disclosed.Type: GrantFiled: December 17, 2013Date of Patent: April 25, 2017Assignee: Ecolab USA Inc.Inventors: Aaron D. Martinez, Erick J.
