Using BOE:

a) Calculate DD&A for 2019.

b) Calculate DD&A for 2019, assuming that part of the field, a proved property with gross acquisition costs of $30,000, gross equipment cost of $70,000, and gross IDC of $215,000, was abandoned during 2019.

14. Taft Oil Company computes DD&A on a field-wide basis. Balance sheet data as of 12/31/18 for Taft's West Texas field are as follows: Unproved properties, net of impairment.. $ 200,000 Proved properties .. $ 500,000 Less: Accumulated DD&A. (100,000) Net proved properties... 400,000 Wells and equipmentIDC. 3,000,000 Wells and equipment-L&WE. 1,400,000 Less: Accumulated DD&A-Wells.
