Proven safe and effective for deepwater operations

KHP-G is a safe, naturally occurring hydrocarbon resin with unique chemical properties. Added to drilling fluids, it increases performance and reduces cost in deepwater drilling while minimizing risk.

The deeper you look, the more benefits you’ll see

KHP-G has been proven safe and effective in more than 60 years of oilfield performance. With natural bonding and plugging properties and a high softening point, it is a cost-effective, multi-purpose additive.

  • Extends thermal life 10% or more
  • Prevents lost circulation
  • Minimizes differential sticking
  • Stabilizes shales
  • Performs in WBM and SBM
  • Performs in HP/HT environments
  • Reduces cost polymers
  • Delivers higher performance with no HSE risk

KHP-G reduces costs more than 80%

KHP-G is a fraction of the cost of premium polymers. With its high softening point, it delivers greater cost advantages at higher temperatures.

KHP-G extends thermal life

PALAYESH PARAFFIN KHAVARAN have yielded variations of uintaite with a range of softening points. Carefully selected varieties of pure Gilsonite® have been combined to perform to customers’ specifications, at temperatures as high as 500°. Adding KHP-G extends the thermal life of synthetic-based mud and water-based mud formulations by 10% or more.

A case history: KHP-G eliminates deepwater differential sticking

An international oil company drilling below 16,000 ft. in the Gulf of Mexico encountered a major pressure regression, and the pipe became differentially stuck. Unable to free the stuck pipe, the oil company and the drilling fluids provider decided to sidetrack the well, re-drilling the section with a zero fluid loss WBM.

Onsite testing indicated that sized particles and calcium carbonate in combination with high concentrations of KHP-G resulted in < 0.5 cc HPHT fluid loss, and fluid loss was nil as measured with a permeability plugging apparatus. Using the reformulated WBM, drilling proceeded through the major pressure regression without any sticking tendencies in the problematic wellbore.

KHP-G is proven under pressure.®

Unique Bonding And Plugging Properties Prevent Formation Damage

KHP-G forms a physical and chemical bond with permeable formations, creating an effective seal to prevent the passage of drilling fluid. By uniquely

functioning as both a malleable and solid plugging agent, KHP-G controls fluid loss and seepage, prevents lost circulation and protects reactive and low-reactive shale surfaces, even at elevated bottomhole temperatures.

KHP-G is naturally better

KHP-G is a naturally occurring hydrocarbon resin found only in northeastern Utah. KHP-G has significant health advantages over synthetic products.

  • KHP-G is:
    • Non-toxic (unlike coal or fly ash)
    • Non-carcinogenic
    • Non-mutagenic
  • No extreme safety measures are needed to handle KHP-G
