In this paper, successful field applications proving the advantages of a new high-fluid-loss, high-strength (HFHS) lost circulation solution in different fields, formations, and sections will be covered in detail. The paper will also...

... Abstract This paper describes a trial jet pump application for offloading a killed well. The Well-2A was naturally producing an average 1650 BCPD and 1.54 MMSCFD from two separate formations via dual strings of size 2-3/in. in a 7 in. casing. It later required a workover job because of tubing...
