Abstract
Summary
This paper presents the technological solutions to problems of cementing wells on the fields of PJSC “LUKOIL” in Western Siberia, related to the absorption of cement slurries due to low fracturing pressure, of high risk of annular flow due to minimum size of bridges between water and the part of oil formation. Also resolved an issue associated the cementing of wells with using thermo-gas treatment of the formation (TGT).
The presented technological solutions with the special cements allowed to a large extent solve the above problems and improve the quality of cementing on the fields of PJSC “LUKOIL” in Western Siberia.
