... Abstract Perforations-reduced connectivity to the producing formation is an ongoing industry challenge. Whether it is caused by high debris or formation compaction, this reduction can be as high as 90%. Several methods were developed to overcome the reduction. Methods such as dynamic...

... problems, such as perforation shutoff, gravel-pack isolation, fracture shutoff, poor zonal isolation, and/or casing-leak repair. Because of the capability of the SPCS system to withstand pressure, workover operations have been successfully performed in previously treated wells, including acid stimulation...

... Abstract The downside of the conventional perforating method with explosive charges and guns is that it is risky. In addition to this, the method has a negative effect on the near wellbore permeability, and it creates mechanical damage. The impact stress associated with shaped charge...

... Abstract Perforation performance can be greatly reduced when encountering multiple casings where depth of penetration and crucially reduced entrance holes prevent effective gravel placement. A practically proven case study is presented on the design, equipment selection and execution...

... Abstract Perforations are required to establish effective hydraulic communication between the wellbore and the surrounding formation. An often considered key attribute is to achieve maximum penetration, providing an effective flow path by extending through the near-wellbore damaged region...

... propped width of 1.3 cm (0.51 in). The large width was needed to achieve sufficient fracture conductivity for the expected reservoir permeability and to minimize convergent flow pressure drop in the fracture, due to the short perforated interval that was used. A very short perforated interval was used...

Even if a lot of models dealing with formation damage already exist for oil and gas producers, only very few models are available for CP water injectors. This paper presents a new model which allows simulating formation damage occurring while...

... Abstract In case of hydrocarbon production optimization it is essential to know the relationship between the inflow rate and the performance of a perforated production well. It describes the flow rate at the bottom of the well in function of the applied drawdown pressure. The process...

Two additional reservoirs are included in this paper where dipole sonic logs were run only in the horizontal cased hole...

... Abstract Perforation is the most common way to establish effective communication between the reservoir and the wellbore in wells completed with casing. Although perforation with shaped charges has become the dominant method for completion, conventional shaped charges do not always provide deep...
