Pressure_BuildUp_WellTest_Calc

This is an improved version of Pressure BuildUp WellTest Calculator.

Free App for download.

Pressure BuildUp WellTest Calculator computes skin factor parameter, S when tp (production time before shut-in) is on the order of one hour.

Pressure BuildUp WellTest Calculator computes skin factor parameter, S when tp>>1hour.

Pressure BuildUp WellTest Calculator computes reservoir permeability parameter, K for pressure buildup test (well testing --straightline method).

Pressure BuildUp WellTest Calculator is developed primarily to offer assistance to petroleum engineers, reservoir engineers, researchers, petroleum production engineers, drilling engineers, completion engineers, petrophysicists, petroleum geologists, students (undergraduates, postgraduates, etc.), and other oil and gas professionals compute the desired parameters: reservoir permeability, K and skin factor, S.

Testing a well (oil well) in order to obtain relevant data which can be analyzed to broaden the knowledge and understanding of hydrocarbon properties and characteristics of the petroleum reservoir form the basis for OilWell Test Analysis.

OilWell Test Analysis plays a vital role in petroleum and reservoir engineering. It's one of the important keys to understand well and reservoir performance.

Input parameters for Pressure BuildUp WellTest Calculator include: production rate, oil formation volume factor, oil viscosity, semi-log straightline slope, formation thickness, flowing BHP at time=0, production time before shut-in, pressure at time=1hr, formation permeability, formation porosity, total system compressibility, well bore radius, etc.
