Waterdrive Product Details

Waterdrive is a collection of classical Waterdrive calculations and routines intended for Petroleum Reservoir Engineers to :

1. Analyse the water-oil displacement processes for both homogeneous single layer and heterogeneous multi-layered systems, and permit the calculation of waterflood performance with time for oil recovery, producing watercut and water injection.

2. Examine and interpret the waterdrive performance of reservoirs, or numerical simulation models, from an inspection of their production & injection history, by solving Welge's equation in reverse.

3. Calculate the waterflood performance with time for a five-spot pattern, using the approach of Craig, Geffen, and Morse for relating oil recovery and producing WOR to cumulative injected water.

4. Calculate Dykstra-Parsons and Lorenz Heterogeneity coefficients.

5. Calculate the waterflood performance with time, using two approaches based on the original work of Dykstra-Parsons, which also relates oil recovery and producing WOR to cumulative injected water.

6. For water coning in vertical and horizontal wells, determine the critical flow rate, breakthrough time predictions and performance calculations after breakthrough.

7. Numerous other smaller routines, or general utilities, are provided to allow efficient calculation of mobility ratio, displacement efficiencies, areal sweep, various conversion utilities and fitting Corey curves to relative permeability data.
