The actuation device includes an actuation tool connection interface and a disintegration device. The disintegration device is configured to be at least partially moved into the frangible obstruction device and thereby provide disintegration of the frangible obstruction device, hence allowing fluid flow between the first end and the second end of the through bore. | ||||||
| 85 | HYDRAULIC ANCHORING ASSEMBLY FOR INSERTABLE PROGRESSING CAVITY PUMP | EP16854655.4 | 2016-10-14 | EP3362637A1 | 2018-08-22 | FORD, Francis John Guillena |
| A hydraulic anchoring assembly (10, 10a), and method of its use, for anchoring and sealing an insertable progressing cavity pump on rods in a well. The assembly (10, 10a) has one or more cup seals (42, 42a), upstream of one or more inflatable packers (14, 14a) upstream of one or more hydraulic slips (16). The cup seals (42, 42a) provide a pressure differential for inflation of the upstream most inflatable packer (14), which in turn provides a pressure differential for the downstream inflatable packer(s) (14a) to inflate to produce a fluid tight seal between the insertable progressing cavity pump and the well. In highly deviated wells the up seals (42, 42a) can be used to pump the hydraulic anchoring assembly (10, 10a) down the well in situations where the rods would otherwise buckle. | ||||||
