Technologies

The discovery, evaluation and extraction of georesources that are sustainable, responsible and efficient has become a highly technical undertaking.

By providing innovative solutions across the entire value chain that address our clients’ priorities, Qteq delivers unparalleled opportunities to streamline exploration and production processes.

Our clients are then able to benefit from reduced environmental impact, increased safety and an enhanced social licence to operate.

Permanent downhole pressure surveillance

Continuous monitoring of downhole pressures and temperatures facilitates a range of development and production optimisation strategies. However, Qteq knows and ensures these systems are:

  • Configured to deliver measurements with accuracy, resolution and long-term stability
  • Engineered to contend with the in-situ environment
  • Robust enough to provide long-term reliable performance
  • Freely configurable to suit a wide range of completed designs
  • Able to facilitate permanent and semi-permanent (retrievable) deployment methods
  • Modular, for safe and time-efficient installation.

 

 

To date, our Qteq team has successfully installed 4,000+ gauge systems across Australia, with a 93% success rate.

We have also logged more than 100,000 hours installing systems. Our gauges are tailored to client needs and consider each client’s characteristics, boreholes or well designs.

Because we focus on operational excellence, Qteq delivers high installation success rates. Our rigorous staff screening and training processes ensure we retain only the highest-calibre operatives who are committed to our core values.

 

We have also compiled extensive quality management systems to govern and verify all our operations.

Through our extensive network of suppliers, Qteq offers several different pressure sensor types, covering a variety of pressure ranges, capable of either analogue or digital transmissions.

Qteq has also pioneered several different gauge architectures and deployment methods that allow countless gauges, regardless of type, to be installed either on tubing, tubing encapsulated conductor (TEC) and/or behind casing.

Borehole Magnetic Resonance (BMR)

Understanding fluid storage and flow in subsurface formations is central to evaluating many different georesource types.

Borehole Magnetic Resonance (BMR) is a unique technology that is sensitive to both the fluid volumes present in a rock as well as the geometry of the pores containing these fluids, providing information on both storage and flow properties.

Not only does BMR track fluid volume and porosity, independent of any lithology effects, it can also differentiate the volume fraction of mobile fluid that can be produced from the fluid volume fraction bound in place in the rock.

Where more than one fluid type is present, such as in oil and gas and coal seam gas applications, BMR also allows the different fluid types to be identified and for volume fractions to be quantified.

The pore geometry information obtained directly from BMR measurements also allows permeability and hydraulic conductivity to be determined, providing an understanding of how effectively the fluids will produce.

Although BMR technology has been routinely used in the oil and gas industry since the early 1990s, tools developed for this application have typically been too large, too complex and, thus, too costly for use in other georesource sectors.

Qteq has developed fit-for-purpose BMR tools that meet both the environmental and commercial requirements of the groundwater, mining and coal seam gas markets, while still being suitable for use in oil and gas applications.
