Protect the formation and reservoir productivity with specialized minimally damaging fluids

A greater focus on open-hole completions has seen a significant push towards the use of specialized, minimally damaging reservoir drill-in fluids (RDF).

The Newpark family of RDFs are optimized to each individual application for maximum reservoir productivity while minimizing damage. They are ideal for all open-hole completion designs as the RDFs maximize reservoir production and injection, reduce potential for formation damage, minimize drilling and completion costs, and tackle various drilling and completion challenges.

Newpark engineers a complete family of RDFs with the target of depositing an impermeable yet easy-to-remove filter cake that are fully compatible with the suite of optimized breaker systems. The RDFs offer application-specific fluid loss control, rheological profile, and lubricity amongst other properties to meet the desired goal.

To ensure uniform and efficient removal of the filter cake, each system undergoes a rigorous test protocol resulting in a fit-for-purpose RDF and breaker system.

Reservoir Drill-in fluids case studies

CleanDrill™ monovalent brine-based RDF

Our flexible and minimally damaging CleanDrill™ monovalent brine‑based reservoir drill-in fluid (RDF) delivers high-performance in a wide variety of operations. With easy filter cake clean-up and low drawdown pressures.

The main advantages of CleanDrill™ RDF

  • Monovalent system
  • Low rheological profile
  • Excellent cuttings transport
  • Superior fluid loss control

CleanVis™ viscosifier provides the necessary rheology profile to achieve excellent cuttings transport while the CleanTrol™ starch provides robust filtration control and generates the impermeable, readily removable filter cake.

Resolution invert emulsion RDF

Designed to meet the drilling performance of an invert emulsion drilling fluid while achieving the filter cake removal efficiency of a water-based fluid. A minimally damaging, invert emulsion reservoir drill-in fluid, Resolution RDF is designed meet the drilling performance of a conventional invert emulsion fluid while mitigating formation damage mechanisms such as oil-wetting, emulsion blocking and solids plugging.

Maximize reservoir productivity with efficient cleanup and filter cake removal using ORCA for WBM technology

ORCA uniform breaker technology is a highly effective, single treatment filter cake cleanup solution available in formulations for oil-based and water-based drill-in fluid filter cakes.

For CleanDrill RDF and CleanDrill HD RDF cleanup applications, ORCA for WBM employs an “in‑situ” organic acid generating package to dissolve acid soluble materials such as calcium carbonate present in the filter cake. This tailored and optimized acid generating package greatly improves acid placement in order to uniformly dissolve carbonate in the mud cake across the wellbore face. This uniform placement results in excellent zonal coverage across long open hole horizontal or directional sections.

Protect the reservoir and mitigate lost circulation with bridging additives

Using our NewBridge™ software as part of the RDF design process, we design the particle size distribution of the bridging additives to match the pore size distribution of the reservoir and to mitigate lost circulation in highly fractured formations.
