WTKI Well Test Design Toolkit

WTKI Well Test Design Toolkit

WTKI is the leading provider of Well Test Consultancy Services including subsurface, training and software. Our Well Test Software calculates from reservoir to flare tip, validating your design to ensure the you can meet your test objectives.

The WTKI Well Test Design Toolkit provides a suite of web-based software tools, as listed below, for well test engineers to easily execute the various tasks involved with well test design. The software is web-based which ensures that any updates or changes made to the functionality of any of the tools are immediately available to users.

Our Toolkit

Pipe Flow Simulation used to model the flow of different fluids through any combination of pipes including pipe accessories such as valves and elbows etc. The application will graphically and digitally present the results of the modelling, with outputs including pressure drop along the pipe, temperature, vibration, fluid velocity, erosion velocity etc.
Noise Calculation tool used to model the noise generated at the flare or across any pressure drop such as the Separator PCV or the choke manifold. The intensity of the noise at different distances can be output graphically and digitally.
PSV Sizing used to calculate the minimum orifice size needed for a relief valve allowing the user to enter the different variables such as set pressure, overpressure, and other variables It also takes into account backpressure in the discharge piping.
Heat Radiation Modelling tool used to calculate the heat intensity from a flare at any distance or orientation. This is important for understanding the heat radiation hazards posed to personnel that are working at the facility and for specifying control measures such as flare placement or heat suppression systems.
Atmospheric Gas Dispersion used to model the behaviour of gas releases to the environment in order to understand how the release moves and disperses, in particular to model the extent of the flammable atmosphere or the Lower Explosive Limit (LEL) of the release as it moves downwind. This is an important part of the design for routing and positioning of relief and vent lines.
Flare Stack Modelling tool models the plume rise and shape as it emerges from a flare stack and moves downwind. This is used to specify the location and positioning of a vertical flare stack in relation to the facility.
Gas Property Calculation used to determine important gas properties based upon gas composition. This is useful when studying gas well tests since the gas properties greatly influence many of the other aspects of the design.
Gas Flowrate Conversion used to convert between a volumetric and mass flowrate taking into account the gas properties to provide an accurate mass flow rate from volumetric flow, or alternatively it can output a volumetric flowrate from a known mass flow rate.
Choke Calculations used to model the behaviour of either single phase gas or two-phase oil and gas flow across a choke. It can calculate the flow rate based on a known choke size, or alternatively predict the required choke size based on a given flow rate. It will also model the Joule Thomson temperature drop across the choke which is useful when performing hydrate studies.
Pressure Control Valve Sizing used for specifying the PCV position and separator pressure. This tool models the flow of gas across standard separator control valves considering downstream discharge pipe sizing. This is an important tool to help determine at what pressure the separator should be set for the PCV to safely control the separator pressure for a given set of conditions.
Leak Rate Calculation used to perform inflow tests, for example, on a TRSV or a plug. By inputting the fluid properties and the observed inflow test data, the Leak Rate Calculator can be used to show whether the plug or barrier is in fact leaking based on the fluid properties.
The Well Flow Simulator models pressure & pressure gradient, temperature, fluid density & velocity, and a range of other parameters throughout the wellbore. Calculations can be performed from bottom to top (i.e. predicting surface conditions based on bottom hole conditions) or from top to bottom (i.e. figuring out what the bottom hole conditions must be if you have only surface measurements). The temperature gradient can be modelled rigorously or based on measured data. This is a versatile tool that can be used for a range of applications such as sizing the tubing string for your well test, or calculating how your bottom hole pressure is evolving during a series of wireline perforating runs.

We are just adding the finishing touches!
The WTKI Well Test Design Toolkit will be live soon.
