| dc.description.abstract | In recent years, research using biomaterials in drilling fluid design has thrown light on their biodegradability, availability and low cost. Apart from these, they have in some cases shown properties superior to those of synthetic materials. This research assessed Mucuna solannie as a fluid loss control agent, looking at its fluid loss, filter cake quality, rheology and comparing them with those of Sodium Asphalt Sulfonate which is a commonly used drilling mud additive. The Mucuna solannie additive was prepared by removing the shell and the seeds sliced into pieces, soaked in water for 3hrs, then grounded into powder form, dried in anovenfor2hrs at 120 of which is an optimum temperature of retaining the chemical properties and finally sieved and re-grinded until finer powder was recovered. The additives were assessed at varying concentrations of 2ppb, 4ppb, 6ppband8ppb, the results obtained were filtrate volumes of 5.5ml against 4.8ml at 2ppb, 5.0mlagainst 4.5ml at 4ppb, 4.5ml against 4.2ml at 6ppb, and 4.1ml against 3.8ml at8ppb, all at 30mintues. Field standard value is 5.0ml fluid loss. Filter cake thickness was 1mm for all concentrations of Mucuna solannie. On rheology, plastic viscosity, yield point and yield stress were 27cP against 28cP, 19Ib/100ft2 against19Ib/100ft2, and 5Ib/100ft2 against 6Ib/100ft2, showing slight differences in their rheological properties. The chemical structure, molecular binding form of Mucuna solannie shows X-ray diffraction of Mucuna solannie found to be closer tochitosan structure with Calcium salt and organic materials. In terms of Economic Analysis, it could be seen that the Mucuna solannie has a less DCF-RORof 58.0%against62.0% of Sodium Asphalt Sulfonate, which indicates that Mucuna solannie is economically and commercially viable, slightly better and gives less economic cost than Sodium Asphalt Sulfonate. This research also established Mucuna solannie as a good fluid loss control agent according to API and field standards. | |
