... in the next section. Diverter The water injector examples under consideration are high permeability with long perforation intervals. There is a need for diverter in the pumping schedule to ensure stimulation across all the perforation intervals. Two different diversion systems were evaluated...

... multi rate test is important to predict the perforation efficiency. The empirical relation will be developed using machine learning. A simple gas reservoir model is built and then run with variations of reservoir permeability, perforation interval length, near wellbore permeability, and vertical...

... perforating. As more marginal reservoirs need to be unlocked, big entrance hole (BEH) perforation was initiated for the current sand control optimization alternative by SCON chemical reduction with shorter perforation intervals; and for thru-tubing metal screen performance improvement by placement in front...

... and lower configuration. Most coals are thinner than the maximum allowable perforation interval and so the macro looks up and down the borehole to include thinner coals within a potential perforation window. The system then generates the stimulation schedule as described above. The macro continues...

... log, the plug was set across the perforation interval to give the anchor contact with a rough casing surface. The top of the plug, however, was above the perforation interval and became the base for cement. Cement was then continuously dumped on top using a slickline dump bailer in a static condition...

... four permanent gauges were installed in the CRC-2 well in 2011 with these gauges bracketing the perforation interval. The gauges were used to monitor the injection at various stages of water, pure carbon dioxide, impure carbon dioxide and nitrogen. Observations from these gauges have allowed...

... on the completed water shut-off jobs, some lessons learned were to have perforation interval above current oil water contact (COWC), have good historical water shut-off performance at surrounding wells, have good production performance at surrounding wells, have good structural location, and have by-pass oil...

.... In some other wells stackable gun system were used as the perforation technique. Squeezing and bleeding of nitrogen was done to provide underbalance in some cases. For wells with smaller perforation intervals, E-line conveyed guns and sand jet perforation was also used successfully. As an alternate...

...-A, was worked-over on February 22, 2006 to conduct a water shutoff technique on existing perforation intervals utilizing a cement squeeze. Several logs such as RST and Gamma Ray were carried out to identify the fluid movement. Then, the well was produced with an oil rate of 1,200 BOPD and a rapid increase...
