Excellent Performance Shorter cleaning time, Clean Product

All-in-1 Single Stage Displacement Fluid

  • During OBM mud or invert emulsion mud cleaning, it’s normally dictated to use of several clean up pills which consist of solvent pill, wetting agent pill, and clear brine pill – a wash train that cleans the wellbore of the invert fluids and produces a water-wet state. This process involves longer time and preparation steps.
  • Hextar KCS’s WellClean is a highly effective, single-stage well displacement cleaning additives. WellClean with its ultra lFT provides excellent cleaning performance in shorter time and just with a single pill.

NanoEmulsion Based Product, Powerful in cleaning and water-wetting

  • WellClean is NanoEmulsion based product which is proven has better cleaning performance than microemulsion or doublemeulsion products. During cleaning process, nano size of droplets remove, dissolves, and disperses oil and synthetic-base-mud residue. Afterward, WellClean leaves all downhole tubulars and metal surfaces in a water-wet state.

Stable, Weighted to Stable, Weighted

  • Hextar KCS has series products that full fill customer requirement. WellClean 100 and 200 are designed to maintains its efficient performance when the wellbore pressure differential requires the wash spacer to be weighted in heavy brine. In addition, the product is effective over a wide temperature range and is ideal for deepwater applications.

Delay Effect in Cleaning

  • Hextar KCS has developed products that can be used to remove OBM filter cake at open hole completion and has tested of its capability to kick start mud removal after more than 12 hours in open hole and allow full removal in designed time.
