It is used primarily in upper-hole drilling to minimize bit and bottom-hole assembly (BHA) balling, reduce surface tension, and aid in dropping sand and the removal of drill solids. It may be used as an emulsifier at any point in the drilling operation to improve emulsification of oil and reduce the viscosity of oil-contaminated fluids.

D-D frequently reduces torque and drag, even when no oil is present in the system. Normal treatments range from 0.1 to 0.2 lb/bbl (0.29 to 0.57 kg/m3) and provide satisfactory performance under most conditions. In severe gumbo shale areas, 4 to 6 lb/bbl (11.4 to 17.1 kg/m3) concentrations of D-D are recommended to minimize bit and BHA balling; higher concentrations may cause foaming and require a defoamer. D-D is effective in all water-base systems including fresh water, brackish water, seawater and saturated saltwater fluids.

Resinex II H filtration agent should be used at concentrations of 2 to 8 lb/bbl (5.7 to 22.8 kg/m3) for fluid loss control. To achieve optimum solubility the pH should be adjusted above 10.0. Higher density fluids will require greater concentrations of Resinex II additive. For increased bottom hole temperatures use larger concentrations depending on drilling conditions. Resinex II H additive may be pre-solubilized in a caustic solution, and added to the active system as a liquid.

Advantages

  • Bottomhole temperature stabilizer.
  • Controls fluid loss in basically all water-base drilling fluids.
  • Controls shale stability.
  • Does not increase rheology.
  • Has higher temperature performance limits than CMC, PAC, or starches.

RESINEX - EH

Resinex EH resinated lignite additive is formulated to improve both API and HTHP fluid loss and provide rheological stability over a wide range of temperatures in almost any type of water-base drilling fluid. Resinex EH additive is suitable for use in freshwater, seawater and brackish water.

Applications:

Resinex EH additive is used primarily for improving rheological stability and both API and HTHP fluid loss. In laboratory tests with a field mud hot-rolled overnight at 250°F, the addition of Resinex EH product resulted in HTHP fluid loss and rheological properties comparable to those measured when using other resinatedlignites. The normal treatment range is 2 to 10 lb/bbl (5.7 to 28.6 kg/m3). Resinex EH product is designed to have minimal effect on the viscosity of most mud systems and can reduce the viscosity of non-dispersed systems.

Advantages:

  • Does not increase the viscosity of the drilling fluid.
  • Reduces fluid loss in all mud density ranges.
  • Possesses higher thermal stability than starches, CMC and other polymeric fluid-loss control agents.
  • Aids in shale stabilization.

TANNATHIN

Description:

TANNATHIN* oxidized lignite is a naturally occurring material used to reduce fluid loss and deflocculate water-base muds. TANNATHIN lignite is a partially soluble additive which provides thin, low-permeability filter cakes. It is an excellent emulsifier for oil-in-water emulsions as well as a secondary deflocculant and is especially effective in high-temperature applications. It performs exceptionally well in dispersed systems as a synergistic additive with lignosulfonates. It can be used in virtually any water-base fluid.

TANNATHIN additive can be used for rheology and filtration control in all water-base muds. It is especially effective in stabilizing the properties of muds exposed to high temperatures and contaminants such as CO2 and calcium. TANNATHIN additive is especially effective when treating cement contamination. It reduces the high viscosity and pH of cement-contaminated muds and reacts with calcium to lessen the contaminating effects.

Normal treatments of TANNATHIN lignite range from 1 to 8 lb/bbl (2.85 to 22.8 kg/m3). Due to their low pH, TANNATHIN lignite treatments require additional caustic soda or an alternative alkaline material, to maintain a consistent pH. A normal ratio is one sack of caustic soda for every four sacks of TANNATHIN lignite. In high-salinity systems, it is preferable to premix the TANNATHIN lignite in medium-pH freshwater to enhance dispersibility then add the premix to the active system. It is most effective in mud systems with an alkaline pH in the range of 9 to 11.

POLYOL

POLYOL (GRADE – I)

Polyglycol is a medium-cloud-point additive designed for medium – to – high salinity polyglycol systems.It can provide improved wellbore stability, lubricity, high-temperature filtration control, plus reduce dilution rates and bit balling. While Polyol Grade I are most effective when used in conjunction with an inhibitive-salt, such as KCl, in a non – dispersed polymer system, they can be used as additives in most water-base systems. Polyol Grade I is acceptable for most applications specifying low-toxicity additives.

Applications

Polyol Grade I product has application in polyglycol systems in fresh-to-medium high salinity make-up water and can be used in wells with moderate formation temperatures. When used properly, this medium-cloud-point additive helps to stabilize troublesome shales by plugging shale pores, preventing the equalization of hydrostatic pressure away from the wellbore.

Polyglycol systems are generally low-to-medium density, non-dispersed polymer systems utilizing an electrolyte to activate the cloud point polyglycol. They have application where troublesome water-sensitiveshales are to be drilled, and can be used in lieu of oil-base systems for certain applications.

Cloud point" Is the temperature where polyglycol additives change from being soluble (atlower temperatures) to being insoluble (at higher temperatures). Shale inhibition is improved when the polyglycol is insoluble or” clouded out.” The cloud point temperature can be reduced by increasing salinity (or other electrolytes) and/or by increasing the concentration of Polyol Grade I polyglycol.

Advantages:

  • Improved wellbore stability and shale inhibition.
  • Improved lubricity.
  • Improved high-temperature filtration control.
  • Reduced dilution rates and mud consumption.
  • Reduced bit balling potential.
  • Low toxicity.
