21. July 12, 1999, letter from Shell Oil Company to the Department of Commerce.

22. We estimated Texaco's proven regional reserves using the following steps: 1) we calculated the depletion rate for the region and for the United States for BP-Amoco, Marathon, Chevron, and Fina, the only opposing importers for which we had proven reserves and production for both the region and the United States as a whole; 2) we determined the largest absolute difference between the regional depletion rate and the U.S. depletion rate on both an absolute and percentage basis (in this case, the difference for Chevron was 0.78 years, which was 8.17 percent of Chevron's U.S. depletion rate); 3) we calculated Texaco's depletion rate (reserves divided by production) for the United States as a whole, which was 15.43 years; 4) as a conservative measure, we deducted 1.26 years from Texaco's depletion rate (we chose the percentage amount because 8.17 percent of 15.4 years is 1.26 years, which is larger than 0.78 years), which resulted in an estimated regional depletion rate of 14.17 years; 5) finally, we multiplied the estimated regional depletion rate by Texaco's regional production to calculate the estimated minimum regional reserves.
