Some other advantages of jet pumps over other lift systems are as follows (Lea and Henry, 1999):
Typically, no rig is required to retrieve free pumps. In many cases, this may be the primary advantage of jet pump systems as compared to the other systems
Can operate reliably in deviated wells. They can adapt to tight turns up to 24°/100 ft in severity and are as reliable in deviated holes as in straight holes
Have no moving parts and therefore no mechanical wear
Can perform better in higher gas-to-liquid ratio wells than ESPs
Standard jet pumps can operate successfully in temperatures as high as 500°F by simply using high-temperature elastomers for their O-rings and seal rings
Have low maintenance costs
Compact, simple, and rig-free design enables easy transportation to remote well sites
Manufactured using corrosion-resistant alloy
Ability to produce as low as 6 °API oil
Economic Analysis
The selection and suitability of jet pump lift systems are governed by a variety of technical and economic factors. Jet pumps are low-cost items in any application, compared with alternative boosting systems, and can be used effectively to maximize the production performance. A case study was done on a dead well of a mature oilfield, which was completed with dual strings of size 2?-in. and 7-in. casing and producing from two separate formations. The upper formation being produced independently via short string was loaded up for almost 3 years, because the API and GOR from the formation were very low along with high water cut. To revive the well, a jet pump was installed in the short string in a sliding side door (SSD), and the short string was tested first with the long string being isolated (S. A. K. et al., 2016; Brown, 1977).
The results of the study: A dead well was successfully revitalized with the cumulative production of 380 B/D, i.e., an average of 100 BOPD and 280 BWPD, which was higher than the targeted production rates evaluated for this well. The conclusion drawn from this case study was that the jet pump was successfully deployed in the SSD of the upper formation with a 7A N/T combination.
"A dead well was successfully revitalized with the cumulative production of 380 B/D," how many of those is there in Cambay?
