Water_Drive_Index_MaterialBalance_Calculator

Water Drive Index Material Balance 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 evaluate reservoir drive (water drive index) contrubutions to the production of fluids from the petroleum reservoir.

Reservoir drive mechanism is a term often used to describe the prevailing force or forces that drive (push) the production of reservoir fluids (oil, gas, etc).

Water Drive Index Material Balance Calculator is a valuable tool for evaluation of reservoir drive (water drive index) contributions to the production of fluids from the reservoir.

Water Drive Index Material Balance Calculator is complementary tool in the toolkit of the engineer for petroleum reservoir calculations and analyses.

Input parameters for Water Drive Index Material Balance Calculator include:

Np=>cumulative oil production, stb

Bt=>two-phase formation volume factor at current reservoir pressure, rb/stb

Bg=>gas formation volume factor at current reservoir pressure, rb/scf

Rp=>cumulative produced gas oil ratio, scf/stb

Rsi=>Solution GOR at initial reservoir pressure, scf/stb.

Bw=>Water volume factor, (rb/stb)

Wp=>cumulative water production, (stb)

We=>cumulative water influx from aquifer, (rb).
