Reservoir drill-in fluids are specially created for the reservoir's needs; their sole purpose is to minimize reservoir damage and maximize drilling performance, thereby conserving the productive potential of the reservoir. Drill-in fluid is a type of drilling fluid designed especially for drilling through the reservoir section of a wellbore. It delivers all the properties of a drilling fluid but does not damage the formation. Drill-in fluid is designed to protect the pay zone during wellbore construction, maximize the recovery of hydrocarbons, and make cleaning easier. It also lowers the overall operational cost of completion of the wellbore and optimizes the rate of production. Drill-in fluid, also known as drill-in mud, is different from regular drilling fluid in that it is designed specifically to minimize skin friction, improve productivity, and prevent damage to the formation.

The drill-in fluid is usually engineered to match the reservoir’s salinity, water hardness, mineralogy, pH, and emulsion-forming abilities.This helps prevent problems such as clay swelling, precipitate formation, emulsions, and scaling.

A drill-in fluid resembles a completion fluid such as brine, containing only selected solids of appropriate size, polymers, and additives necessary for carrying cuttings and for filtration control. Thixsal reservoir drill-in fluid mainly contains water as a base fluid and reinforcement additives, sodium chloride, calcium carbonate, etc., that enhance rheological properties and superior filtration control. It also contains xanthan gum and other biopolymers that control the viscosity properties of the drill-in fluid. This unique polymer combination is synergistic, yields improved static suspension, and provides a highly shear-thinning viscosity under dynamic conditions.

Thixsal drill-in fluids are also applied in drilling, completion, and workover operations to provide a low fluid viscosity at high shear rates, an elevated solution viscosity under static conditions, and superior filtration control. It is also infused with necessary reinforcement additives to reduce filtrate invasion into the productive zone, thereby minimizing internal formation damage. Reservoir drill-in fluid, completion, and workover fluids are classified under special fluids, and they make a crucial economic difference in the drilling process. They are used in the final well stages and bring a higher profit to all the companies involved in the drilling process. When drilling into a reservoir zone with a conventional fluid system, a series of risks or problems, can affect the reservoir by plugging the reservoir pores and/or fluid invasion into the productive formation. The composition of a drill-in fluid depends on the formation being drilled.

At Centum, scientists and engineers have been researching and analyzing commercially available reservoir drill-in fluids and their performance in various well-completion projects. After years of research and development, scientists have formulated the most effective Thixsal- reservoir drill-in fluid equally effective for onshore and offshore oilfield completion projects. It is laboratory-proven and oilfield-tested, and the necessary ingredients are locally sourced, offering ultimate quality and performance. At Centum, we prioritize sustainability and performance; therefore, our Thixsal- reservoir drill-in fluid helps to achieve ESG targets without compromising performance. At Centum, we custom-formulate reservoir drill-in fluid to meet specific project needs.
