| Abstract | ||
| The adherence of crude oil to metal surfaces (accretion) during the well drilling in the Orinoco Oil Belt (Venezuela) has led to the common use of lubricants in water-based drilling fluid. However, research is currently being carried out to also add a surfactant agent to the fluid to mitigate this problem. The present investigation studied at laboratory level the use of petroleum coke distillate (DC) and the surfactant this distillate (SDC) for this purpose. Infrared (IR) Spectroscopy of both distillates showed that both fluids showed common spectra surfactant agents. Likewise, the addition these to a viscoelastic polymeric fluid contaminated with oil and petrolized sand brought the physical properties closer to the values the uncontaminated fluid (blank). When both fluids were studied as friction reducing agents (COF), they showed good capacity, reaching values associated with oil-based fluids. As accretion reducing agents, fluids with CDS and CD at 1% concentration showed better performance than a commercial additive from a service company. Statistically, it was shown that there is no statistically significant difference between the 2% and 3% CDS additive, so the recommended concentration is 2% CDS. | ||
