Among the most important characteristics for proppant selection are strength and bulk density. Current standard procedure for measurement of proppant strength is based on concentration of 4 lb/ft 2...

The importance of the required injection-gas throughput performance of a GLV for unloading and gas lifting a well increases for very high daily liquid production rate wells and for wells that the workovers are very costly. A test procedure that allows individual...

... recommendation (P/N = 3.7); and written procedures should be used for running plugs on coiled tubing (P/N = 2.2). The risks associated with running in with CPs on coiled tubing are similar to the case of electric line. However, the probability of CP damage increases because detection of obstructions does...
