Viscosifiers / Shale Inhibition - Water Based Drilling Mud

DX-HEC 40 L is a high performance liquid version of HEC (hydroxyethylcellulose) polymer suspended in a high-quality mineral oil with proprietary ingredients in a 40% active that builds viscosity yet provides ease of handling and mixing in the field.

DX-HEC HV/UHV is a high viscosity, or ultra-high viscosity, hydroxyl ethyl cellulose ether designed for use as a viscosifier in brines and saline fracturing fluids, workover fluids, completion fluids and drilling fluids. It gives pseudoplastic rheology but essentially no gel strength development.

DX-HEC MV is a medium viscosity hydroxyl ethyl cellulose ether designed for use as a viscosifier in brines and saline fracturing fluids, workover fluids, completion fluids and drilling fluids. It gives pseudoplastic rheology but essentially no gel strength development. It can thicken, suspend, bind, emulsify, form films, stabilize, disperse, retain water, and provide protective colloid action. It is a free-flowing powder that readily dissolves in hot or cold water without excessive mixing or heating.

DX-LQ. GIL is a uintaite (natural asphalt) suspension which can be used in place of regular powdered gilsonite® in any drilling fluid system. It provides all the beneficial properties of gilsonite® in a liquid form, without adversely affecting the drilling fluid system.

DX-LQ. Xanthan has been proven to be extremely effective in providing viscosity to thicken drilling mud. When circulation stops the solids still remain suspended in the drilling fluid. The demand for good control of the drilled solids has led to its expanded use in horizontal drilling.

DX-PAC LV is a high purity/premium, low molecular weight, water soluble anionic polymer of sodium salt of carboxymethyl ether of cellulose, tailored for use in water based fluid systems where no additional viscosity increase is desired. The primary function of DX-PAC LV is to reduce and control the API filtration rate while stabilizing the rheology of the mud without substantially increasing the viscosity regime of the fluid system. It also provides shale inhibition as a protective colloid and improves the filter cake quality and stability between the wellbore and the formation.

DX-PAC R is a high purity/premium, high molecular weight, water soluble anionic polymer of sodium salt of carboxymethyl ether of cellulose, tailored for use in water based fluid systems for increasing viscosity while controlling filtration at low rates. The primary function of DX-PAC R is to improve the viscosity of the drilling fluid to the desired degree while controlling the water loss at the lowest possible rates. By adding the product, increased apparent viscosity and yield point are obtained, subsequently better and higher drill solids transfer capacity is established.

This high molecular weight liquid PHPA provides viscosity development and hole cleaning capability in addition to shale encapsulation properties. DX-PAL 30 has been used successfully for over 20 years to stabilize sloughing shales in fresh, KCl and salt water based drilling fluids. The liquid emulsion formulation offers a high activity product in a low viscosity, easy to handle product.

Our dry counterpart to the DX-PAL 30. The DX-PHPA is a granular powder with excellent handling and mixing properties. This product offers all of the performance characteristics of the liquid PHPA but has the economic benefits of a high activity powder.

SHALE-BLOCK is a sulfonated asphalt that is water soluble and primarily used as a shale stabilizer. SHALE-BLOCK is resistant to common mud contaminants and has exhibited high temperature stabilizing properties on weighted muds.

An asphaltic based shale stabilizer that is dispersible in both fresh water and sea water environments. SHALE-TONE can be used as a preventative treatment for sloughing shales or to overcome existing problems in shale sections. SHALE-TONE also provides some fluid loss properties as well as wellbore stabilization and lubrication.
