CHOPS Without Sand
Heavy oil producers in Canada have adopted the primary production strategy of encouraging sand production in a process commonly know as Cold Heavy Oil Production with Sand (CHOPS). While this technique yields economic oil rates, the production of sand introduces many other operating costs and prevents the implementation of technologies, such as gathering lines, that are not compatible with massive sand production. A new concept has been proposed that takes advantage of the reservoir processes of CHOPS but removes most of the extra operating costs and barriers to technology associated with sand production. This paper discusses the new process, how it could benefit heavy oil production operations and the technical challenges that need to be addressed before this concept can be implemented.
