    Environmentally friendly fluid loss control agent in water-based mud for oil and gas drilling operations
    (Research India Publications, 2017) Onuh, C. Y.; Igwilo, K. C.; Anawe, P. A. L.; Daramola, Olakunle; Ogunwomoju, Omotoke
    The fluid loss properties of mud formulated with concentrations of coconut shell and/or corncobs was studied. This study is focused on formulating water based drilling mud using corn cobs and coconut shell as additives in improving the performance of the mud. The additives were varied in different concentrations and its impact were evaluated on the filtration properties using low pressure low temperature (LPLT) filter press at 90 °C and 100 psi. The result of the formulated mud with corn cobs and coconut shell additives were compared to that of the mud containing corn cobs alone, coconut shell alone, and without any of the additives. The results showed that the combination of corn cobs and coconut shell reveals a lower filtrate volume than individual coconut shell and corncobs. However, Corn cobs is a better fluid loss control agent than the coconut shell.

    Evaluation of the effects of alcohol on de-emulsification of Niger Delta crude oil using commercial de-emulsifiers
    (Scientific Research Publishing, 2017-07-14) Igwilo, K. C.; Okolie, S. T. A.; Anawe, P. A. L.; Ogbudu, Roland; Odo, Jude
    This research work evaluates the effects of alcohol on de-emulsification of Niger Delta crude oil using RP6000 and Chimec 2439 as de-emulsifiers. The laboratory measurements were carried out as per API standard. Stable emul sion was prepared using brine. The samples were de-emulsified. Methanol and ethanol were added respectively, with water and without water as modifiers. The measurements of the effect of adding alcohols on water separation effi ciency were carried out using methanol to water ratio, M = 4:1 and ethanol water ratio, E = 4:1. The results show that solubility with alcohol is greater in emulsion than the solubility of alcohol without water. Some comparisons were also made based on the plots on percent water separation versus time for the two modifiers and de-emulsifiers. The maximum separation efficiency of 61% was obtained at concentration of 25% methanol, 75% RP6000, 20 ppm and Chimec 2439 gave maximum separation efficiency of 56.6% at concentration of 75%, 20 ppm at 120 minutes. Based on the results, methanol therefore gave larger effect on water separation efficiency than ethanol
