Pure-Bore® chemistry forms the basis for a range of next generation high performance water based mud systems – HPWBM. Clear Solutions proprietary Pure-Bore® chemistry is specially reacted from natural materials to create polymer chains which interact and cross-link. By carefully controlling the Pure-Bore® chemistry, Clear Solutions have been able to manufacture a range of viscosity grades, all with a unique membrane forming ability and surface-active properties.
The base Pure-Bore® drilling fluid system provides superior shear thinning and drag reducing characteristics, developing very low ECDs and optimised hydraulic horsepower at the bit. Its use significantly improves hole cleaning and ROP’s, particularly in large diameter and long lateral sections.
The unique Pure-Bore® membrane forms a very effective, non-invasive, solids free, slick filter cake. This effectively stabilises challenging formations and reduces the risk of differential sticking, whilst maintaining reservoir protection. The Pure-Bore® membrane also generates excellent shale stability and lubricity, minimising torque and drag, positively impacting non-productive time (NPT).
Furthermore the Pure-Bore® membrane with its surface-active structure, provides excellent shale encapsulation characteristics – reducing cuttings degradation.
Utilising a Pure-Bore® HPWBM system, drilled cuttings are removed from the hole more efficiently, with a larger particle size. In addition with Pure-Bore®’s low screen blinding tendencies; finer shaker screens can be run. The net effect is lower mud consumption and reduced waste disposal costs, resulting in significant cost reductions for the operator.
Pure-Bore® chemistry is compatible with a wide range of commonly used oilfield chemicals and it can be used in a wide density range of monovalent and divalent brine types.
Pure-Bore® provides a safe and easy to manage drilling fluid system. This enables rapid mixing of a highly stable mud system, which is tolerant of a wide range of typical oilfield contaminants such as cement, calcium, magnesium, carbonate and low gravity solids.
In summary Pure-Bore® chemistry forms the base for a highly effective, ultra high performance water based mud system which can be used to drill the entire well from top hole to reservoir section, whilst providing optimum environmental protection.
The real benefits of the Pure-Bore® HPWBM include:
- Lower ECD’s / significantly reduced risk of down hole losses
- Optimised hole cleaning, higher ROP’s and reduced NPT
- Reduced torque and drag
- Improved lubricity
- Significantly reduced formation damage through enhanced reservoir protection
- Proven to optimise gas/oil recovery rates in low permeability reservoirs
- Superior shale inhibition
- Improved wellbore stability
- Solids free fluid loss control
- Non-toxic and easy to use
- Environmentally friendly performance
