Definitions

  • the fluid process of the present invention relates to the technical field of drilling of oil, geothermal and similar wells, whose formations are considered of different pressure gradients and have high temperature conditions, in which drilling fluids are applied.
  • High temperature can create problems for water-based drilling fluids by altering their behavior, chemical reactions that affect the performance of chemical materials used for drilling fluids, accelerate at higher temperatures and there is a growing tendency for thermal flocculation.
  • Thermal degradation of chemical materials can affect rheology, filtration and alkalinity properties, modifying them to unstable. These altered properties can cause reduced penetration speeds in the drilling of the well, greater pressure losses, loss of circulation, instability of the hole and the possibility of stuck pipe. Controlling fluid properties at high temperatures often requires expensive maintenance treatments.

  • This HIGH PERFORMANCE HIGH PERFORMANCE WATERPROOF PHASE POLYMERIC FLUID, SPAT® adapts to the high technical requirements of drilling, such as high temperature stability, prevents delayed preparation of fluid systems as it is prepared on site and in turn favors the advancement of drilling, thanks to its high performance products. It also reduces the cost of logistics for ships, eliminates the use of liquid products (diesel, drilling water or brine) and avoids time lost due to material shortages.
  • This fluid has a low toxicity compared to others, the chemicals used in this fluid reduce the risk of exposure due to its design, coupled with the above, the physical presentation of each chemical component of the fluid allows for a more agile and safe operation for the staff that operates the well and prepares the fluid. And finally use oil-free water-based fluids, since accidents with a massive effect can occur and catastrophic spills can be caused to the environment, With the fluid designed to comply with these regulations it is possible to mitigate the environmental impact with drilling fluids.
