**Oil recovery equation**. Many argue that it is no better than analogies to other producing formations. Fundamentals of fluid flow in porous media. Using the length of the core in the equation of dimensionless time 71 5 2 correlation of the results for the systems with different boundary conditions.

Plot oil recovery from. Change equation select to solve for a different unknown oil recovery factor. The basic equation used to calculate recoverable oil reserves is where rf recovery factor which equals rf p rf s.

Solving for oil recovery factor. Oil recovery by capillary imbibition of water into a matrix block from a fracture can be estimated from the relationship r r 1 exp λ t where r is oil recovery at time t r is the limit toward which recovery converges and λ is a constant specifying the rate of convergence towards the asymptotic limit. The recovery factor value predicted by the benchmarking equation is called a field quality index fqi.

When the rates are low as the pressure gradient is increased the oil recovery factor increases. Use the equation below to estimate the recoverable oil or gas in a reservoir. However in the higher rate range as the pressure gradient is increased the oil recovery factor even decreases.

Chapter 4 immiscible displacement water injection oil recovery calculations. The primary recovery factor rf p is estimated from the type of drive mechanism table 2. The api or arps equation for oil recovery of solution gas drive reservoirs is the result of an empirical multiple regression of 80 solution gas reservoirs.

Ep o is estimate of in place oil. It is as follows. X figure page.

Looks impressive but is it any good. Before water breakthrough t t bt in the producing face well eq. Estimating recoverable oil or gas depends on predicting reservoir quality and reservoir drive.

Equation for calculate oil recovery factor orf er o div. Er o is estimate of recoverable oil. Estimate of recoverable oil ero.

An approximately linear relationship can be observed. For the shale models the oil recovery factors are very low with the maximum 0 0261. Estimate of recoverable oil.

Reservoir analogs help narrow the range of values for variables that determine recovery factor r f.
