The micro-sonde well logging system is a concept for obtaining along-well measurements of temperature, changes in fluid velocity and pressure while drilling. The micro-sondes are encapsulated, self-contained measurement devices designed to follow the flow from the bottom hole assembly to surface. On...

The DESCRAMBLE project has developed novel drilling technologies for a proof-of-concept test of reaching deep geothermal supercritical resources. In the project, we have drilled and tested the continental-crust condition for demonstrating novel drilling techniques, the control of gas emissions and h...

Exploitation of super-critical water from deep geothermal resources can potentially give a 5-10 fold increase in the power output per well. Such an improvement represents a significant reduction in investment costs for deep geothermal energy projects, thus improving their competitiveness. The ongoin...

The micro-sonde well logging system utilizes miniaturized data logging devices, which are released at the bottom of a well and record downhole parameters whilst being transported by fluid flow to surface. The μSonde capsules are designed to be small enough to pass restrictions without obstructing th...

This paper presents the thermal performance of a proposed thermal management device (patented in 2009) intended for a thermophoresis-based soot sensor. The performance was studied for temperatures ranging from 50 to 400 °C and for exhaust speeds up to 10 m/s. It also presents the design and bas...
