... was carried out. The acquired neutron logs showed flushed zone from two former producing perforations as well as remaining hydrocarbons in the upper perforated zone. The gamma ray log activation was detected just below the oil water contact while the oxygen activation log "OAI" was highlighted just above...

... Abstract Some completion operation steps, such as perforation and packer seating, require that the degree of uncertainty be limited. The main correlation methods used today are based on tally accuracy, tagging a known element in the well or using wireline gamma ray readings. This paper...

... Abstract This thesis presents the results of a study evaluating the application of high powered lasers when perforating cement-lined wells in carbonate rock reservoirs. The focus is on the creation of lateral channels in the walls of the well to allow the flow of the oil into the well. Through...

... To determine perforation performance, service companies conduct tests to demonstrate the advantages of different technologies of perforating systems. Although studies on jet penetration into rock targets usually focus on the prediction and measurement of penetration depth the repertoire...

.... Typical gas wells were drilled as a vertical cased hole through the reservoir or open hole horizontal gas wells. The increased well deviations, measured depths and resultant increase in reservoir sections required a new approach to the perforating solution for these wells to connect them to the gas...
