Abstract Asphaltene and humic acid products widely used in oil base muds (OBMs) have deficiencies such as seriously viscosifying the OBMs, high concentration requirement, limited filtration control performance and poor high temperature stability. An aqueous acrylic resin, WAR, was developed for use in OBMs to solve these deficiencies. WAR was synthesized with monomers such as styrene,
butyl acrylate, and acrylic acid through emulsion
at 237 °C (weight loss by 2%), as proved by

rheology, filtration control perfomance, plugging capacity
and high temperatu
terized with IR spectrometry. WAR remained stable
evaluated in laboratory for its emulsion stability, stability both in conventional OBMs and clay-free
OBMs. It was shown that WAR performed positively in stabilizing the properties of emulsions. Emulsions treated with WAR remained their whole emulsibility after 24 h of standing, WAR had very slight effect on the rheology of OBMs, and appreciable filtration control ability, plugging capacity and high temperature stability. HTHP filter loss tested at 180 °C was less than 5 mL, with the mud cake being dense. After aging at 180 ° C for 16 h, the percentage of forward plugging was more than 75%, and that of backward plugging was moer than 70%. Compared with oxidized asphalt, the aqueous acrylic resin had better overall performance as an OBM additive. The working mechanism of the aqueous acrylic resin in invert emulsion drilling fluids is also analyzed in this paper.
