Qteq has made substantial investments in R&D of in-situ measurement technologies that replace slow, costly core sampling and analysis techniques. Our in-situ monitoring technologies are designed to provide real-time, actionable data to boost georesource productivity, reduce overall operational costs, and preserve the environment.
We provide our suite of products and services across the Carbon, Capture & Sequestration (CCS), Groundwater, Coal Seam Gas, Coal Mining and Onshore Oil & Gas industries.
To ensure we remain relevant to these industries, we focus on delivering the latest sensor technologies, ruggedized to maintain superior operational reliability, complemented by world class deployment service excellence.
Carbon, Capture & Sequestration (CCS)
The aim of Carbon, Capture and Sequestration (CCS) is to prevent the release of large quantities of waste carbon dioxide (CO2), a greenhouse gas (GHG), into the atmosphere. Capture of CO2 emissions by heavy industry and from heating is considered a potential means of mitigating the impact of this GHG on climate change and ocean acidification. The CCS chain consist of three steps:
Capture CO2 from large point sources, such as new and existing coal- and gas-fired power plants, and other large energy intensive industrial sources, such as cement factories and steel foundries.
Transport the CO2 to a suitable storage site (usually as a compressed gas in pipelines).
Inject the CO2 in deep underground rock formations for safe, long-term storage. These formations are often a mile or more beneath the surface and consist of porous rock that holds the CO2. Overlying these formations are impermeable, non-porous layers of rock that trap the CO2 and prevent it from migrating upward and ultimately escaping as fugitive emissions.
To provide ongoing assurance to communities that the CO2 remains locked in place, subsequent long term rigorous monitoring of CCS sites is essential. Qteq offers a range of products and services to help identify suitable geological formations for permanent CO2 sequestration, to characterise in-situ injection conditions, map the subsequent migration of CO2 plumes throughout the disposal formation over time, and monitor the long term integrity of overlying geological traps, as well as mechanical integrity of injection and monitoring wells.
Coal plays an important role as the primary source of energy for the generation of electricity worldwide.
However, the coalification process that converts plant matter to fuel also produces methane and carbon dioxide gases, so the depositional process can leave the coal cleat structure and surrounding formations filled with water.
Safe extraction of the coal requires advance knowledge of coal gas content, water filled porosity and system permeability because these will be used to guide water and gas pre-drainage strategies.
Qteq is able to quantify all three parameters in situ, using its flagship Borehole Magnetic Resonance (BMR) logging tool.
A proprietary NMR excitation pulse sequence and analysis technique, referred to as T2-StimD, has been developed to detect and quantify adsorbed gas content in the coal matrix, as well as any free gas content in the cleat structure.
Onshore Oil & Gas
The harsh conditions encountered in conventional oil and gas reservoirs impose the need for robust, rugged and reliable monitoring tools to successfully characterise the hydrocarbon resource and optimise development strategies.
Qteq’s range of mature product offerings and services is ideally suited to addressing such challenges.
Our design and supply of permanent downhole pressure-monitoring systems is based on a rigorous assessment of well conditions and client monitoring needs, by our dedicated Applications Engineering team.
Coal Seam Gas (CSG)
The responsible and efficient development of natural gas, from coal, requires innovative technical solutions, delivered in high volume, at an affordable price – outcomes that have often eluded the coal seam gas (CSG) industry.
Qteq has amassed a portfolio of products and services that delivers those outcomes to optimise CSG well productivity and boost recovery factors.
We have the experience, perspective and skills to help you make your CSG development produce more gas, faster and with a smaller environmental footprint.
Groundwater is a vital resource of social, agricultural, environmental and economic benefit, with known supplies dwindling through continuous population growth and industrial expansion.
Hydrogeology therefore plays a critical role in the development of comprehensive groundwater management strategies to protect this vital resource.
The social licence to operate that is granted by shareholders, communities and governments to energy companies – particularly those developing unconventional resources such as coal seam gas – requires that those operators undertake extensive hydrogeological studies to mitigate the impact of their operations on nearby aquifers.
Qteq provides a range of innovative technical solutions to help hydrogeologists develop an in-depth understanding of the vertical and lateral extent of these aquifers, aquifer flow potential, and to map groundwater movement into and out of these aquifers over time.
