In the drilling process, in order to prevent the collapse of the hole wall, sand (water), water leakage, or to separate the water layer, the metal or non-metal pipe is used to drill into the borehole to maintain the drilling and ensure the normal drilling technology. Measures, called Perforated casing holes.
Features of Perforated Pipe:
Casing and perforated completion is the most common type of completion which is selected my many co***nies. For this completion, a production casing or a liner is cemented through reservoir zone(s) and subsequently, a well is perforated in order to provide communication between the formation and wellbore.
Perforation should ideally penetrate deeper rather than nearer a wellbore damage zone around a wellbore so fluid from a reservoir can effectively flow into a wellbore. Additionally, several depth control methods help to accurately select which section of reservoir to be perforated. Hence, undesired zones, such as gas, water or weak formation can be avoided and this will improve well production efficiency. |
