Openhole perforation
Webperforated using a wireline perforation gun. As the pressure inside the production pipe is held at a value that is lower than the formation pressure, the formation will produce fluids, which by this stage in the well completion, should be hydrocarbons. If the test produces sufficient hydrocarbons, the production 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’.
