Commingled Well Model

Modelling zonal contributions and overall well behaviour in multi-zone commingled completions is made easy using our CWM software. This tool facilitates commingled reservoir analysis at the well or the field level, matching production logging results to yield layer volumes and reservoir properties.

Validation

Well Test & Subsea facilities are complex systems which are hazardous to operate and yet fulfil an important task. Validation is a recognised step in the process to provide assurance that a system has been designed in a manner consistent with industry standards and regulatory requirements.

We have many years planning and executing these operations in a diverse range of environments. We have also been delivering quality design validations to the industry for over 10 years. Whether you need us to perform a detailed design verification using our in-house simulation software, or a regulatory compliance validation, we can help you, contact us today for support.

Well Simulator

The WTKI well simulator include many features for modelling the behaviour of fluids inside the wellbore regardless if the well is a producer, an injector, or static. There are many useful tools to help the user build a detailed description of the well including; well trajectory, multiple internal diameter changes, and different pipe roughness values. There is also a subsea option to allow the user to specify subsea conditions, this is useful to take into account the cooling effect of the ocean where the heat transfer across the subsea riser will be different from the geothermal gradient below the mudline. The simulator can model any fluid mixture, dry gas, wet gas, live oil, dead oil and water. It also provides the user with options to choose from a wide range of industry recognised fluid property correlations.

Simply enter the flowing conditions, either bottomhole, or surface, to get the resultant set of conditions along the length of the entire well. There are a host of outputs available, everything from pressure, temperature, and fluid velocity, to liquid and gas holdup plots, fluid density, erosion velocity and turner velocity plots.

WTKI Toolkit

The WTKI Toolkit is a suite of web based applications available to engineers and designers to perform a wide range of tasks connected with well test facility design. The convenience of the web based applications means there is nothing to download and install on your local machine, it also means the software is readily accessible wherever you happen to be working.

There are many applications within the toolkit, for example the pipe flow simulator, which models single and multiphase fluid behaviour in pipework and production equipment, this tool allows the user to anticipate production conditions and optimise the design of the facility.

The well flow simulator can be used to model the behaviour of fluid in the wellbore, this tool can be used for both production and injection wells, for example, to determine surface flowing pressure and temperature based on tubing size and bottom hole conditions. Similarly, for injection wells, to work out bottom hole conditions based on surface injection parameters.

The toolkit incorporates many sophisticated modelling features, for example, a wide range of multiphase flow correlations are available to choose from for both oil and gas properties. Other tools within the toolkit include; PSV sizing, Hydrate modelling, Gas dispersion, and Heat & Noise radiation modelling.

The toolkit interface is very user friendly and a full set of help files are accessible to take the user through the different tools.

The WTKI toolkit offers a cost effective and powerful set of tools to anyone in the industry who needs to perform everything from a gas composition analysis to a full well test design.

Hydrates & Well Testing

Hydrates are ice-like solids that form when hydrocarbons and water mix under certain conditions of temperature and pressure. These solids can form at temperatures well above the freezing point of water and often present a hazard during well test operations.

WELL TEST KNOWLEDGE INTERNATIONAL

 

Well Test Knowledge (WTKI) is truly international and has been providing well test support services to the oil and gas industry in many parts of the globe.

Testimonials

Well tests are not a regular run of the mill type of operation for anybody in subsurface, drilling, completions or associated functions. As such well tests require careful preparation and planning in order to execute in a safe and effective manner. The well test execution course from WTKI provides a thorough grounding in the totality of the full value chain required for proper well test project management and is an excellent foundation step to beginning a well test project for all functions involved in a well test
