Decline curve analysis

Decline curve analysis is a way to figure out how much oil and gas is left in a well. First, we need to measure how much oil or gas is flowing out of the well. Over time, the flow rate usually decreases. So, every month or so we measure the flow rate. We then plot these measurements on a graph. The shape of the graph on the graph is what we call a "decline curve". With the decline curve, we can make predictions about how much oil or gas is left in the well and how fast it is going away. This helps us decide when it is time to start looking for new wells.
