OIL FIELD CHEMICALS FROM MACROMOLECULAR RENEWABLE RESOURCES IN NIGERIA: AN INTEGRATION OF HYDROCARBON RECOVERY WITH BIORESOURCE UTILIZATION
Nigeria is ranked as Africa's largest oil producer (the 6th largest producer globally) with a crude oil production capacity up to 2.7 million barrels per day. The country's gas production is about 1.7x108cubic meters per day. The investment in the oilfield chemical subsector of the Nigeria oil and gas industry is about 100 million dollars. On the other hand, Nigeria is blessed with various naturally occurring multi-component materials some of which are by-products of large scale industrial processes. The country is the 6th and11th largest raw cashew and coconut producer in the world, respectively. Nigeria also produces other crops such as sugar cane, plantain/banana, guava, pawpaw, and varieties of vegetables. The huge amount of waste generated from the harvesting and processing of these crops can be upgraded to value added products for application as oilfield chemicals. This paper presents an overview of the potential application of agro-biomass wastes in the oil and gas industry. Specifically, research outcomes on the use of these waste materials for drilling fluids, well completion fluids, enhanced oil recovery, and gas shut-off are discussed. The paper seeks to provide information and production technology that are needed by indigenous entrepreneurs who are interested in small and medium scale oilfield chemicals production.
