Our Innovative Approach


OEMG – Global has never been content to sit with the status quo. Constantly looking for innovative ways to value add to client services. To produce results that minimise risk, maximise outcomes and reduce project costs. Competing on cost alone and being forced into reduced quality was not acceptable so we made a strategic decision to value add.

OEMG challenges “Business as Usual” practice with an innovative approach to ground modelling.  Revolutionising the way in which current tender processes are conducted to allow for innovation, a fairer tender process and significant cost and environmental savings.

Successfully establishing a market niche by approaching principles directly, rather than through traditional tender procurement processes. This lead to the breakthrough method known as Integrated Digital Ground Modelling (IDGM) a method that is highly sort after as it produces significantly improved results.

OEMG have developed innovative methods allowing them to become positioned as strategic ground modelling experts and consultants. They work directly with  Australian and overseas organisations and government departments who are tasked with making strategic decisions about public infrastructure placement and design. They are in a position to contribute to a transformation of traditional procurement processes which will aim to encourage further innovation within the industry.

Supporting organisations to collect and combine all relevant datasets into a “Strategic Integrated Digital Ground Model (IDGM)” which covers an entire area of decision making influence and is available for use by multiple departments. Thereby reducing duplication of effort, increasing data confidence, improving strategic planning & holistic infrastructure placement.

OEMG takes an innovative approach to the market segments they operate in and as a result of many years of extensive experience and research have developed a new approach to ground modelling that will help clients save time and money.

Back in the early days

Jason in Dubai many feet above the ground

It had to start somewhere. Here is Jason installing a GPS repeater many feet above the ground on the mast of the Burj al Arab in Dubai. Someone had to be crazy enough to get up there!


OEMG-Global is started

Namibia Diamond Search

Initially contracting on oceanographic and projects all around the world including Kazakhstan, Libya, Qatar, UAE, Djibouti, The Congo and many more.


2009 Aquares Resistivity System Introduced to Australia

OEMG-Gobal  introduces the Digital Geophysics to the Australasian region.


Demand for OEMG's Digital Geophysics grows

Macedon Pipe Route Exmouth

Demand quickly increased resulting in rapid expansion.  Projects included Cape Lambert dredge assessment for Van Oord and the Macedon Pipe route land and marine survey.

2011 - 2012

OEMG Reputation Grows

Working in the niche market of the Oil and Gas Industry OEMG became known for its strong reputation for quality innovative services.  Developing proprietary processing techniques that provided clients with qualitative and quantitative project planning data that clients soon realised was superior to what they could obtain elsewhere. Projects included Grove, NT (pipeline route assessment), Port Headland Port Expansion, Hay Point (Magnetometer Survey)

OEMG team members demonstrate strong history of success within the industry View some of the projects.

2012 - 2013

Resources boom crash

Seal Rocks Land Slip – Great Lakes Council

Resources boom crash causes decline in the Oil and Gas Industry allowing the opportunity to diversify into the Public Infrastructure market.

Projects included: large job in PNG for Mitsubishi-Talisman for Daru Port Expansion, Great Lakes Council with the Seal Rocks Land Slip (land survey gear established in Australia). Early iterations of ideas for the IDGM begins.


IDGM Developed and Tested

Eden Port

The development and on project testing of  IDGM – piloted with a number of land, freshwater and marine environment projects in Yamba for Clarence Valley Council and NSW Public works including Yamba ebb-tide release, Orara river underbore and the mains water replacement. Working directly with innovative clients such as Clarence Valley Council and NSW Public Works, OEMG developed award winning IDGM methodology that revolutionises the industry.


IDGM Accepted by Industry

NSW Metro Survey

IDGM comes into its own, Port work explodes with jobs for Eden Ports, NSW Ports and Gladstone Ports.
State innovation award winner.  Extensive lobbying starts against restrictive tender processes that specify technology rather than outcomes.

2015 and the hard work pays off
2016 - 2017

OEMG using IDGM wins major projects

Gold Coast Water IDGM data collection

2016 – OEMG wins Sydney Metro work.
OEMG contracted by Gold Coast Water and starts process of working towards a Strategic IDGM that can be used for multiple projects. Incorporation of other data into the integrated model and advice on how to use it. Multiple Departments realise that they can now start to use to their IDGM for a wide range of projects – another industry first!

2016 - 2017

OEMG using IDGM wins major projects

2017 – Continuing to innovate.
OEMG launches the IDGM branding and the IDGM strategic product!

IDGM Strategic is aimed and councils, government departments and proponents. Structural geophysical assessments can be made of large areas and tested over time for specific projects utilising targeted geotechnical studies. We have now made the IDGM even more cost effective.

OEMG-Global have been lucky to have worked with some clients who value our innovative approach to the industry.
We appreciate the comments they make about our approach to our services.
  •   OEMG Global provides specialist skills in oceanography and environmental management services. Through projects such as the metro train for the NSW Department of Transport and with the NSW Port Corporation, OEMG Global have demonstrated how well they work hand in hand with government and non-government agencies in bringing their projects to successful conclusion. OEMG Global utilises world leading technology and is uniquely placed to provide excellent advice regarding the Taiwan wind farm development. It is my pleasure to endorse this innovative company

  •   "We are finally done with the guesswork!" (Quote from US Army Corps of Engineers after a successful Aquares resistivity survey following previous inconclusive survey campaigns)

    - US Army Corps of Engineers,
  •   "Boskalis uses for different projects geo-electric surveys to quantify and qualify rock outcrops. For the geological setting near the coast of Luderitz (Namibia) geo-electric survey is preferred above conventional reflection seismic since gravels above the rock outcrop might diffuse the signals. Also it is believed that reflection seismic will not give information about the rock strength characteristics, while geo-electric survey data can."(Advise from Boskalis BV to Namport with regards to the geophysical methods to be used in the port of Luderitz)

    - Bokalis BV,
  •   This is to acknowledge that OEMG mapped significant parts of the Botany Port seabed, operating around working vessels in a few days utilising the Aquares System. Works were completed on time and within budget and our objectives were met: OEMG’s mapping allowed assessment of the condition of the subsoil directly adjacent to the wharf structures allowing us to verify the stability of the structures for current and future use.
