Hydraul-EZ: Maintaining borehole integrity demands a drilling fluid you can count on for all drilling conditions: Hydraul-EZ. Hydraul-EZ is a specially formulated bentonite drilling fluid that offers superior suspension properties and borehole stability for all soil conditions. Use it, and learn why Hydraul-EZ has become the product of choice among experienced drillers.
Recommended dosage for normal conditions is 20-30 lbs./100 gals. water. Packaging is 50 lb. bags.

Super Gel-X: Super Gel-X is produced from the highest grade sodium bentonite. This easy mixing, high viscosity, 200-bbl. yield drilling fluid is ideal for all types of fresh water drilling. It mixes quickly and easily, reduces solids while increasing lifting power, removes cuttings, cools and lubricates the bit, and helps prevent loss of circulation while stabilizing boreholes.
Recommended dosage for normal conditions is 15-25 lbs./100 gals. water. Packaging is 50 lb. bags.

Clay Slip liquid polymer emulsion contains partially hydrolyzed polyacrylamide/polyacrylate (PHPA) copolymer. It is used primarily as a borehole stabilizer to help prevent reactive shale and clay from swelling and sloughing. Clay Slip polymer is also added to low-solids drilling fluids to help increase lubricity, fluid viscosity, and to help improve carrying capacity of air/foam injection fluids.

Importance of using high quality HDD Drilling Fluid

To ensure you maximise in the life of your Downhole Tooling, high quality drilling fluids must be used. Drilling fluid is composed of a carrier fluid (water) and drilling fluid additives (bentonite and/or polymers). The most widely used drilling fluids for HDD applications are based on bentonite. Bentonite is a naturally occurring clay mineral (montmorillinite) that forms a mud when mixed with water.

  • Cools downhole tools and equipment
  • Lubricates to reduce friction between the drill pipe / product & the bore wall
  • Cleans off build-up on drill bits & reamer cutters
  • Stabilizes and seals the sides of the borehole
  • Carries the cuttings out of the hole

The following factors must be considered:

  • Viscosity

    Viscosity is the resistance of a fluid to flow. Maintaining the proper flow is imperative to successful HDD drilling.

  • Gel Strength

    Gel Strength is the ability of the drilling fluid to support, suspend and carry cuttings. If proper suspension is not maintained, the cuttings will quickly collect around the drill pipe or product line being pulled. This could cause a loss of circulation and a build up of pressure, resulting in a ‘frac out’ and possible loss of the tool.

  • Low Fluid Loss

    Fluid Loss is the measurement of filtrate (free water) passing from the drilling fluid into a porous permeable formation. Low Fluid Loss is a characteristic of good drilling fluids and the key to borehole integrity. The goal of a good drilling fluid is to create a thin filter cake on the sides of the borehole. This prevents the excessive loss of fluids into the formation.

  • pH

    The pH is an expression of the acidity or alkalinity of a solution measured between 0 and 14 with 7 being neutral. It is critical to maintain the proper pH of drilling fluids to ensure optimal performance. In HDD projects pH should be maintained between 8 and 9. Soda Ash is the simplest means of raising the pH level.

Mud Testing Equipment Kit

Includes:

  • 4-Scale Metal Mud Balance
  • Sand Content Kit
  • Marsh Funnel Viscometer & Cup
  • pH Testing Strips
  • Stopwatch

Sand Content Kit

Determines the volume percent of sand-sized particles in the drilling fluid It is important to know the sand content of drilling muds because excessive sand may result in the deposition of a thick filter cake on the wall of the hole. High sand content may also cause excessive abrasion affecting pump parts and pipe connections. Sand sized particles are defined as anything larger than 74 microns. This test can be performed on low solids muds as well as on weighed muds.

Marsh Funnel Viscometer

Used for routine quick measurements of fluid viscosity The Marsh Funnel Viscometer is an excellent indicator of changes in drilling fluid properties. Viscosity is a measurement of a fluid's resistance to flow: the greater the resistance, the higher the viscosity. As measured by the Marsh Funnel, the viscosity of the fluid is influenced by the density of the fluid (solids content) and gelation rate (beneficiated solids content). The viscosity of the drilling fluid in use should be based on a combination of the following parameters: drilling rate, pump and output capacity, mud density, cutting size, hole size and solids removal equipment.
