The main goal of core analysis is to reduce uncertainty in reservoir evaluation by providing data representative of the reservoir at in-situ conditions. Core analysis has to be integrated with field and production data to minimize reservoir uncertainties that cannot be addressed with other data sources such as well logging, well testing or seismic. These requirements define the coring objectives, core handling and core analysis scheme. These objectives cannot be achieved by coring a single well. Coring program is ...

The completion string is the most important component in petroleum production system and should be designed and installed precisely, and maintained properly. If the well suffers scale production problem the importance is multiplied. In this study the four major completion techniques commonly used for non-organic depositions is introduced. The subject has been case studied for one of southern Iranian oil wells with inorganic material production problem. The simulations were run using the Prosper software, and were ...
