Introduction

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

•	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.

•	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.

•	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 water-oil ratio (WOR) to cumulative injected water

•	Calculate Dykstra-Parsons and Lorenz Heterogeneity coefficients

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

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

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.

License.dat File

The "License.dat" file is located in the Application Startup folder (eg C:\Program Files\Petroleum Solutions\Waterdrive\)

The contents of this ASCII license file needs to contain the following license information.

If any of the above License key information is incorrect or absent, or if the License.dat file is missing then the application will fail to startup.

.NET Framework

The Profile application requires the presence or installation of Microsoft .Net Framework version 2.

.NET Framework version 2 is a component of the Microsoft Windows® operating system used to build and run Windows-based applications.

Should .NET Framework version 2 not be installed on the destination PC then a link is provided below to download this system software. The user should download and install .NET Framework version 2 before attempting to install Waterdrive.

The installation of .Net Framework also requires a minimum software and hardware requirement. Details of which are shown below. Specifically, note that you cannot install the .NET Framework on a computer running the Microsoft Windows 95 operating system.

Minimum requirements

To install .NET Framework [Dotnetfx2.exe], you must have one of the following operating systems, with Microsoft Internet Explorer 5.01 or later installed on your computer:

• Microsoft® Windows® 98

• Microsoft® Windows® 98 Second Edition

• Microsoft® Windows® Millennium Edition (Windows Me)

• Microsoft® Windows NT® 4 (Workstation or Server) with Service Pack 6a

• Microsoft® Windows® 2000 (Professional, Server, or Advanced Server) with the latest Windows service pack and critical updates available from the Microsoft Security Web site (www.microsoft.com/security).

• Microsoft® Windows® XP (Home or Professional)
