To describe the fluid behavior and petroleum reservoir pressure distribution as a function of time, three important types of flow regimes must be acknowledged. These are steady-state flow, unsteady-state flow and pseudosteady-state flow.
Oilwell Production Calculator is developed primarily to offer assistance to.petroleum engineers, reservoir engineers, researchers, drilling engineers, petrophysicists, petroleum production engineers, completion engineers, students (undergraduates, postgraduates, etc.), and other oil and gas professionals compute the oil production rate Q, in steady-state flow.
Oilwell Production Calculator computes well production rate Q, in steady-state flow and the steady state solution is applicable after boundary effects have been felt.
Input parameters for Oilwell Production Calculator include: boundary pressure, flowing pressure, reservoir thickness, formation volume factor, viscosity, drainage radius, well radius and skin (note: Enter zero for skin parameter, if it is not considered), all parameters expressed in oilfield units.
