摘要:
A two-component lost circulation material (LCM) is provided. The two-component LCM includes a polymer component and a sodium hydroxide component. The polymer component may include may include a drilling fluid, a fibrous material such as polypropylene fibers, and an acrylic polymer, such as a 30% acrylic polymer solution. The sodium hydroxide component may include water and sodium hydroxide. The sodium hydroxide component is introduced to contact the polymer component to form the two-component LCM. Methods of lost circulation control and manufacture of a two-component LCM are also provided.
