Abstract (2. Language): 
A model for prediction of crude oil blend property was chosen for development of a linear programming problem, which was solved to obtain optimum composition of three crude blends (Shell’s UQCC, Chevron’s ESCRAVOS and Arab light crude) that minimizes cost and meets quality standards required for lubricant production. Results show that the optimum blend for the two Nigerian crude oils (UQCC & ESCRAVOS) and the foreign crude (Arab light crude) is that with 36.36% by weight of UQCC and 63.64% by weight of Arab light crude, with an API gravity of 31.4091 oAPI. Although the pure Nigerian crudes are not suitable for lube base oil production, it was found that 36wt% UQCC blended with 64wt% Arab light is suitable for lube base oil manufacture, meeting all the accepted quality standards at minimum cost. This blend can be used in Nigerian refineries to minimize importation of foreign crudes, with a reduction in the associated economic and technical problems.
