Case Study in Economic Impact of Using Drag Reducing Agent on Cost of Pumping Crude Oil in Western Desert, Egypt
Crude oil is pumped at the rate 14,200 bbl/d from FARAS field to BEDR3 field (58 meter higher in elevation) at western desert in Egypt through 6 inch x 34.2 miles pipeline using two identical pumps connected in series, working at best overall pumping efficiency. A one megawatt diesel engine is used to generate necessary power for motors run the two pumps. This paper presents economic analysis for impact of using Drag Reducing Agent (DRA) in reduction cost of oil pumping, keeping same pumping flow rate where one of the two pumps is temporary abundant. Economic analysis is applied for the two pumping cases; case-1) Using two pumps without DRA (Table 1) & case-2) Using only one pump with DRA (Table 2). Items of such analysis are: 1) Cost of the consumed diesel amounts in both cases. 2) Total cost of DRA including daily rental rate of injection skid, daily hiring rate for operators and price of used DRA in gallon per hour. 3) Cost of pumps and their maintenance over pipeline service life.
