Maximum Efficiency Rate (MER)
Definition - What does Maximum Efficiency Rate (MER) mean?
Maximum Efficiency Rate refers to the maximum sustainable daily gas or oil withdrawal rate from reservoirs that permit depletion and also the economic development without causing damage to the ultimate recovery. It is the maximum rate at which the gas or oil can be produced without harming the natural energy in the reservoirs.
If the oil or gas is extracted at a greater rate than the reservoir's Maximum Efficiency Rate, the natural pressure of the reservoir will decrease, which results in less oil that is ultimately recoverable.
The Maximum Efficiency Rate is also known as the The Maximum Efficient Rate.
Petropedia explains Maximum Efficiency Rate (MER)
The Maximum Efficiency Rate is the well production rate that determines the maximum volumetric recovery of reservoirs with minimum residual oil saturation at the depletion. It is commonly used to denote the rate of field production that can achieve the maximum financial return from the reservoir operation. However, the figures of two rates hardly coincide.
The computed Maximum Efficiency Rate can be used as a cost-effective tool for reserve potential evaluation for the preliminary assessment of the column properties of oil.
