It is a liquid polyamine, shale inhibitor used in polymer-base drilling and drill-in fluids.Shale inhibition is achieved by preventing water uptake by clays, and by providing superior cuttings integrity. The additive effectively inhibits shale or gumbo clays from hydrating and minimizes the potential for bit balling. The RXSOL ORG shale inhibitor can be added directly to the mud system with no effect on viscosity or filtration properties.
The RXSOL ORG Shale inhibitor is a liquid additive that acts as a clay hydration suppressant by intercalating and reducing the space between clay platelets so that water molecules will not penetrate and cause shale swelling. The RXSOL-81-8140-210 additive provides outstanding shale inhibition and minimizes dilution rates.
RXSOL-81-8140-210 inhibitor chemistry additionally provides a buffered pH in the 9.0–10.0 range, eliminating any required additions of caustic soda or potassium hydroxide. The recommended concentration is 1–4% by volume, depending on shale reactivity and the amount of shale in the interval to be drilled. RXSOL-81-8140-210 inhibitor concentrations should be monitored using a filtrate amine titration method. Premix dilution rates should be based on the depletion rates and the polyamine inhibitor concentration in the premix.
For reservoir, drill-in fluid applications such as in the Flopro * NT system, inhibitor compatibility with the reservoir should be evaluated through formation damage testing and filtrate/formation fluid compatibility testing.It is important to monitor the cuttings condition at the shakers during drilling operations. Cuttings should be firm and dry inside. Sticky and balled-up cuttings may indicate insufficient inhibition from a low RXSOL-81-8140-210 additive concentration. The initial mixture may contain more. RXSOL-81-8140-210 additive than specified in the mud program to act as a buffer against high consumption (e.g.,4–5% v/v).
RXSOL-81-8140-210 additive can also be used as a shale inhibitor in gravel pack fluids to maintain wellbore stability during high-rate water packs
. The concentration is usually 1–2% for this type of application.
