Worldwide, there are approximately 2 million oil wells and 37.5 percent of these use rod pumps as the artificial lift method. Alternative methods such as electrical submersible pumps, gas lift systems, and progressive cavity pumps are used on 12.5 percent of the wells1. Rod pumps face many operational challenges. Some of these challenges consist of:…
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…
When considering any project in the Arctic or sub-Arctic, one must first be prepared to deal with the remote location.
When a field reaches peak production and becomes mature, keeping its production rate above the economic limit becomes challenging.
Excessive water production is prevalent in mature fields and can impact profitability. It is therefore important to understand what contributes to undesired water production.
Geomechanics modeling is especially important for minimizing the special challenges and problems posed in the deepwater drilling environment.
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.
The field deployment of polymer flooding offers several potential benefits for extending the life of mature reservoirs. (Continuation)
The field deployment of polymer flooding offers several potential benefits for extending the life of mature reservoirs.
Of critical importance, exploratory wells both represent the initial reservoir evaluation opportunity and help define subsequent development strategies. Hence the importance of obtaining high quality data with which to portray accurate static-dynamic reservoir characterization. This is the reason the drill stem test (DST) is one of the most important tests oil companies use to execute…
