Eagle Ford Shale, TX. Wax Problem

This past month one of our project teams has been designing pigging programs down in the Eagle Ford Shale area to remove paraffin wax.  The project involved cleaning a number of 4 inch production lines totaling approximately 6 miles and 3 miles of 8 inch gathering line. Several different types of pigs were run, first in conjunction with hot oil and then with normal well flow. The results of the pig runs were analaysed and a program recommended for the client, including frequency and type of pig to be run.
