  • Use of multiple charged cationic compounds derived from polyamines for clay stabilization in oil and gas operations
    Patent number: 11702586
    Abstract: Multiple charged cationic compounds, which are derived from polyamines through an aza-Michael addition with an ?, ?-unsaturated carbonyl compound, in a clay treatment composition to reduces clay swelling, clay migration, and sludge formation in a subterranean formation in oil and gas operations are provided. The disclosed methods or compositions are found to be more effective than those methods or compositions commonly used for reducing clay swelling, clay migration, and sludge formation.
    Type: Grant
    Filed: June 30, 2021
    Date of Patent: July 18, 2023
    Assignee: ChampionX USA Inc.
    Inventors: Ashish Dhawan, Kellen Harkness, Carter M. Silvernail, Keith A. Monk
  • Complete removal of solids during hydrogen sulfide scavenging operations using a scavenger and a Michael acceptor
    Patent number: 11499108
    Abstract: Disclosed herein are scavenging and antifouling compositions useful in applications relating to the production, transportation, storage, and separation of crude oil and natural gas. Also disclosed herein are methods of using the compositions as scavengers and antifoulants, particularly in applications relating to the production, transportation, storage, and separation of crude oil and natural gas.
