Article Title: Extraction and Blending of Nigerian Oilsand-Crude with Nigerian Bonny-Light Crude at Various Temperatures for Flow Quality Enhancement
by Thomas A. Adebayo; Fiyinfoluwa I. Oyelade and Oloruntoba Owolabi

Blending of crudes is done in order to obtain intermediary crude of distinct physical properties. Crudes were extracted from Oilsands obtained from Nigerian oilsands at Ode-Irele and Agbabu, all located in Ondo State. The experimental result carried out showed that Ode-Irele oilsand gave an average of 19.49% crude content while the Agbabu oilsand gave an average of 79.8% crude content. The Agbabu yield was very high because the oilsand is actually an outcrop at Agbabu and some of the sand content might have been lost due to filtration as the oilsand flows upward. The viscous Agbabu synthetic crude was then blended with a more expensive and less viscous average Nigerian conventional crude, Bonny Light from River State. This was done in order to obtain distinct crude of cheaper cost than that of the Bonny light and of lower viscosity than the Agbabu oilsand crude. The characteristic flow properties of the blend mixture was studied at three temperatures of 50, 70 and 90oC. At 50oC it was discovered that the blend has distinct flow characteristic when the oilsand crude component is within the range of 33% to 44.5% weight composition of the blend mixture. Outside this range, the blend behaves either as extracted crude above 44.5% oilsand crude composition or as Bonny-Light crude at below 33% of oilsand crude composition. At 70oC the required composition of the oilsand crude to give this distinct flow characteristic is in the range of 33%-39% weight composition while 35% of oilsand crude component is required at a temperature of 90oC.
