| Popis: | The ability of lignin fromRhizophora Apiculata’sblack liquor to act as a fluid loss additive in water-based drilling at HTHP condition was investigated. The lignin biopolymer was extracted from the black liquor using acid precipitation technique using 20% by volume of sulphuric acid at temperature of 45°C and 60°C for pH 4, 6 and 8 respectively. The produced lignin was tested in water based drilling mud at temperature of 250°F, 300°F,350°F and 400°F . The optimum extraction parameters showed that the highest yield of lignin extraction of approximately 51.2% was obtained at pH 4 and extraction temperature of 45°C. It was also observed that theRhizophora Apiculata’slignin has remarkable rheological and filtration controlling properties at HTHP condition as compared to the commercial lignin additive. |
