With the average worldwide recovery factor for oil being 35%, getting the most out of mature wells before abandonment is critical. When a well’s productivity declines (i.e. the flowrate decreases with drawdown pressure remaining constant), there is a tendency to want to immediately plug and abandon it. Instead, the first question should be, “Is there anything we can do to enhance the well’s...
Worldwide, there are approximately 2,000,000 oil wells and 37.5 percent of these use rod pumps as the artificial lift method. Rod pumps face many operational challenges such as, mechanical wear, corrosion, pump failures, and inefficient pumping.
Excessive water production is prevalent in mature fields and can impact profitability. It is therefore important to understand what contributes to undesired water production.
Drilling technology improvements over the last few years are enabling operators to take a new look at mature fields as a source of incremental oil production.
A robust waterflooding plan for mature fields maximizes its profit potential, by minimizing capital and operational expenses whilst maximizing production.
