Openhole perforation
Web26 de jun. de 2015 · Open-hole Completion Open-hole completions are also termed 'barefoot' completions. In this type of completion the casing is set in place and cemented above the productive interval (s). Further drilling extends the well bore into and/or through the reservoir (s) which is left uncased, hence the term 'Open Hole’.

A perforation in the context of oil wells refers to a hole punched in the casing or liner of an oil well to connect it to the reservoir. Creating a channel between the pay zone and the wellbore to cause oil and gas to flow to the wellbore easily. In cased hole completions, the well will be drilled down past the section of the formation desired for production and will have casing or a liner run in separating the formation from the well bore. The final stage of the completion will involve running in perfora… WebDuring perforating, a high perforation density (30–40 perforations/m) and a large perforation diameter (20–25.4 mm) are required in order to increase flow area. Sometimes the reservoir sand outside the casing may be washed out in order to pack gravel into the location of the oil reservoir outside the perforations to avoid mixing of gravel with …
