Abstract Cementing carbonate reservoirs is generally a difficult task. The so-called thixotropic cement slurry has gained
considerable attention in this regard as it can help to fix some notable problems. More precisely, it can easily fill
the leakage layer; moreover, its gelling strength can grow rapidly when pumping stops, thereby increasing the
resistance to gas channeling, effectively preventing this undesired phenomenon in many cases. High-temperature
thixotropic cement slurry systems, however, are still in an early stage of development and additional research is
needed to make them a viable option. In the present study, using a self-developed composite high-temperature
thixotropic additive as… More >
