ABSTRACT
In Nigeria oil and gas industry, chemicals used as pH controllers are imported from foreign countries, and add to the cost of drilling. It is however imperative to discover another medium to control pH, and this is achieved by the use of local materials. This medium should be considered because of its cost effectiveness. This study is geared towards investigating the compatibility and suitably of the use of locally sourced material (Coconut fibre) as the pH enhancer in a typical drilling mud program. The high pH level is needed to suppress the rate of corrosion, the embrittlement of hydrogen and the solubility of Ca2+ and Mg2+ which makes up clay. An environment with a high pH is also favourable for various additives used for viscosity control. With the goal of minimizing cost and improving profit, the locally made additives is being considered to replace the imported product. It is known that Burnt coconut fiber is being used as a pH enhancer, due to the fact that it is eco-friendly, being degradable, and has no adverse effect on the properties of the formation. Furthermore, the results obtained from this study insisted that the effect of the local additives (coconut fibre) gave a pH reading of 13.0 in the drilling mud, whereas the foreign addictive such as sodium hydroxide gave a reading of 13.8
