Improving production begins with correctly identifying the issue causing decreased performance and designing appropriate treatments to increases production and extend the life of the well. To date, more than 4,000 subsea completions have taken place in deep water, and estimates suggest this total will increase by 500 to 600 per year. At the same time, recoveries from these subsea deepwater wells can be disappointingly low - 20% versus an average of 50 to 60% for platform and land wells.
