In this paper, styrene butadiene resin/nano-SiO 2 (SBR/SiO 2) composite was synthesized
by the continuous emulsion polymerization method, which was used as a plugging agent for …

The enhancement of cement properties through the integration of composite materials has
become a prevailing topic, as it offers a solution to the limitations associated with single …

Styrene-butadiene rubber (SBR) modified cement-based material owns many advantages,
however, reduction in compressive strength within cement composite has limited its …

This paper investigated the suitability of xanthan gum as a thixotropic agent utilized in high-
temperature natural gas well cementation. The konjac gum and KCl are used to synthesize a …

In this paper, alumina nanofibers (ANFs) are studied as an additive in the reinforcement of
the mechanical properties for oil well cement composite. To simulate the subsurface …

Under the condition of heavy oil thermal recovery, the cement sheath is easy to crack in the
high temperature environment, resulting in the decrease of cement paste strength, which …

Currently, geopolymer is being considered as a future oil-well cement. For wellbore
applications, geopolymers are initially tested at specific temperature conditions. However …

ABSTRACT Plug and Abandonment (P&A) operations represent a critical phase in the life
cycle of oil and gas wells when they become economically unviable and the …

The mechanical property of cement sheaths is a primary indicator for evaluating the quality
of well cementing in oil and gas wells. With the exploration and development of complex …

Energy losses can be significantly reduced if thermally insulating cement is used for energy
storage and recovery. The thermal conductivity (TC) of the currently used cement is between …
