The magnitude of production increases typical of CHOPS methods by the early 1990s was quantified in an article in the Journal of Canadian Petroleum Technology, which indicated...

... to correction. Abstract 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...

... at optimal rate to ensure pressure drawdown less than critical drawdown threshold for sanding and water coning. Field data confirmed that this trial is successful, with 2 to 3-fold production gain, relatively low water cut and no sanding issue. This technology is a useful option for post-CHOPS wells...

After operating in Lloydminster area for almost 70 years, Industry's experience for the primary CHOPS recovery on average is 8% of the original oil in place ( Coskuner et al., 2015 ). This means that at the end of the primary recovery process, there will still be a very significant...

CHOP operating expenses have dropped from 10-12 $CDN/bbl in 1990 to 6-7 $CDN/bbl in 2000, a testimony to the incremental but cumulative efforts of dozens of innovative engineers, operators, and service providers who continue to find more economical and effective methods. Nevertheless, continuing...
