CDrilling Fluid Productshemject markets a complete array of Drilling Fluid Products; these products have become known as industry standards for many in the industry. The Chemjet products are used in Oil Base Muds (OBM),Water Based Muds (WBM), as well as Synthetic Based Muds (SBM) and Polymer Mud Systems (PMS) as theory, designs and formulations are required.

OIL-BASED MUDS (OBM)
Oil-based systems are used in various applications, where fluid stability and inhibition are necessary, such as high-temperature wells, deep holes, and where sticking and hole stabilization are problems. They consist of two types of systems:

  1. Invert emulsion muds are water-in-oil emulsions, typically with calcium chloride brine as the emulsified phase and oil as the continuous phase. They may contain as much as 50% brine in the liquid phase. Relaxed, invert emulsion muds are a relaxed emulsion, and have lower electrical stabilities and higher fluid-loss values. Concentration of additives and brine content/salinity are varied to control rheological, filtration and emulsion stability.
  2. Oil-based muds are formulated with only oil as the liquid phase and are often used as coring fluids. Although these systems pick up water from the formation, no additional water or brine is added. All oil systems require higher additional gelling agents for viscosity. Specialized oil-based mud additives include: emulsifiers and wetting agents (commonly fatty acids and amine derivatives) for viscosity; high-molecular-weight soaps; surfactants; amine treated organic materials; organo clays and lime for alkalinity.

SYNTHETIC FLUIDS (SBM)
These are designed to mirror oil-based mud performance, without the environmental hazards. Primary synthetic fluids are esters, ethers, poly alpha olefins and isomerized alpha olefins. They can be discharged offshore, and are non-sheening and biodegradable.

WATER-BASED SYSTEMS
Water base muds have been used around the world as they are easier to use and to blend as water is readily available anywhere in the world and can be madeon location.
Water Based Systems can be the following.

  • Non-Dispersed
  • Dispersed
  • Calcium Treated
  • High Performance? (HPWBM)
  • Polymer/PA/PHPA
  • Saltwater Systems
  • Low Solids

IR, MIST, FOAM AND GASFour basic operations are included in this specialized category. These include:

  1. Dry air drilling, which involves injecting dry air or gas into the wellbore at rates capable of achieving annular velocities that will remove cuttings;
  2. Mist drilling, which involves injecting a foaming agent into the air stream that mixes with produced water and coats the cuttings to prevent mud rings, allowing drill solids to be removed;
  3. Foam uses surfactants and possibly clays or polymers to form a high carrying-capacity foam; and
  4. Aerated fluids rely on mud with injected air (which reduces hydrostatic head) to remove drilled solids from the wellbore.
