Introduction This paper reviews the planning by R. J. Reynolds Industries and its wholly owned subsidiary, American Independent Oil Co. (Aminoil), for the acquisition of the U. S. interests of Burmah Oil Co. This acquisition which was completed at midyear last year, was made for a cash consideration of $522 m This was one of the largest cash acquisitions in U.

Following a brief description of the range of properties involved in this acquisition and the conditions under which this acquisition work was done, we shall discuss the specifications set for our approach, the scheduling of our work, the computer model developed for economic evaluation, and some of the other key ingredients that made this acquisition a successful and satisfying effort. This paper, however, will not cover the substantial petroleum engineering work — reservoir evaluation, cost and investment forecasting, risk assessment, etc. — that was fundamental to the property evaluation.
