Pure-Bore® is a unique HPWBM which is highly shear thinning and has superior clay and shale encapsulation with the ability to form an environmentally friendly slick solids free filter cake.
Pure-Bore®’s proprietary construction has natural polymer chains that interact with each other to give superior shear thinning properties that provide very low ECDs optimising hydraulic horse power at the bit and giving exceptional hole cleaning and increased ROP, particularly in large diameter and long lateral sections.
Pure-Bore® is the only single component drilling fluid to form a very effective biodegradable non-invasive solids free slick filter cake on its own. This effectively stabilises highly permeable formations reducing the risk of differential sticking whilst optimising reservoir protection. The Pure-Bore® structure generates excellent lubricity and shale stability, minimising torque and drag.
Pure-Bore® HPWBM is totally compatible with salt-based additives such as Sodium Chloride (NaCl), Potassium Chloride (KCl), Calcium Chloride (CaCl2) which can be added as required to provide further inhibition. Calcium Carbonate (CaCO3) can be added if required as a bridging agent or mud weight.
Pure-Bore® provides significantly better shale and clay stabilisation than standard WBMs which reduces cuttings degradation and LGS build up which further contributes to low ECDs in the well. At surface finer screens can be run as there is less shaker screen blinding giving much lower dilution rates (up to 75% less), resulting in significant cost reduction on whole mud, chemicals and shaker screen consumption.
Pure-Bore® is an easy to manage drilling fluid system which allows rapid mixing, highly stable, non-hazardous product, effectively coping with a wide range of contaminants such as cement and OBM.
In summary Pure-Bore® is 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, significantly improving drilling rates and well productivity whilst reducing non-productive time, mud usage, waste disposal and displacement costs, and more over protecting the environment.
Pure-Bore® is a unique HPWBM that offers OBM comparable performance.The real benefits of Pure-Bore® include;

- Reduced torque and drag
- 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
