Monitoring Gas Migration from Plugged and Abandoned Wells
Our client needed to determine whether gas migration is occurring through cement plugs, assess whether it is continuous or intermittent, and evaluate the influence of ambient conditions. Precisely quantify gas migration rates, monitor headspace shut-in pressure, and capture fugitive emissions for compositional analysis.
Identifying False Positive SCVF in Onshore CSG Wells
Qteq deployed Ventbuster® units to conduct point-source emissions monitoring, capturing wellhead annulus flow data and shut-in pressure. The system accurately measured ultra-low flow rates (0.04 ml/min, ‘One Bubble in 10 mins’) while accommodating high dynamic ranges up to 720 m³ per day. Gas samples from each well were collected for laboratory analysis to determine composition. […]
Delivering Excellence in Resource Monitoring for a Major Mining Operation
A leading mining company in Queensland, Australia, engaged Qteq to support a large-scale resource monitoring and management project. The operation required specialised wireline services to conduct comprehensive data acquisition across multiple sites, ensuring compliance with environmental regulations and optimising water resource management. Despite the complexity of the program, Qteq successfully delivered high-quality data while maintaining […]
QTEQ Wireline Logging in Timor Leste
Qteq was contracted by an Australian exploration company to provide all Openhole, Cased hole, Tubing Conveyed Perforating and Pipe recovery wireline logging services on a remote onshore drilling project in Timor Leste. Qteq successfully mobilised 35 tons of equipment within four weeks to ensure all open hole and cased hole services including explosives were on […]
Understanding Casing Corrosion
In 2022 Qteq became aware that current Casing inspection technologies were unable to reliably identify the corrosion on the exterior of the casing in some Coal Seam Gas wells. Qteq subsequently went on a global search for any company that had the technology to address this problem. As a result, Qteq identified Dexon, a pipeline […]
Replacement of a 7 year Old Fluid Sampling System
In 2019, Qteq successfully deployed a hybrid fibre optic and electronic downhole monitoring system in four deviated wells within the Otway Basin, Victoria. By integrating FibreTraq and ResTraq technologies into a single opto-electronic architecture, Qteq enabled real-time distributed acoustic sensing (DAS), distributed temperature sensing (DTS), and permanent downhole pressure monitoring (PDHG). The project marked a […]
