Products and services
Efficient exploration and appraisal of hydrocarbon discoveries.
The Hydrophilic Logging Tool (HLT) will measure the distance to the free-water-level (FWL) and help determine the size of the accumulation.
New tool on its way
We are now in the design phase of a new tool that will be ready in Q4, 2027.
Prototype HLT
Our prototype HLT is tested Off-shore Norway and is available to book for energy companies. The 17-meter OBM open-hole wireline tool has been designed to perform a single depth measurement in less than four hours. Repeated measurement is possible. Please take a look at our product sheet for more information.
Galileo
HLT version 2 – slimmer (outer diameter reduced from 7 to 6 inches), faster, and with improved measurements. Designed for deeper wells. It will withstand higher pressure and temperature. Construction and testing to be completed in Q4 2027.

Our services.
We believe that nobody can do what we do. Together with our products we can offer different services for energy companies and provide important measurement and information.
Nobody
else can
do this!
These are the unique services we provide.
Measure water pressure (Pw) inside a hydrocarbon reservoir.
The Hydrophilic Logging Tool (HLT) will measure the distance to the free-water-level (FWL) and help determine the size of the accumulation.
Measure pressure difference (Pd) between oil (or gas) and water in the reservoir.
Knowing Pd allows us to calculate vertical distance to the “floor of the reservoir – the FWL (Free Water Level) – in a new discovery. Pd also provides a measure of a reservoirs remaining production potential.
Measure both water pressure (Pw) and oil pressure (Po) with the same sensor.
“Dual Purpose Sensor”. The HLT can measure both water pressure (Pw) and oil pressure (Po) with the same sensor.
Measure in-situ Kw(Swi)
Kw(Swi), the permeability of the water film on the grain surfaces inside an oil (or gas) reservoir can be very low, but the HLT can still measure it.
Measure the pressure in formations with ultra-low permeability.
The HLT can measure the pressure in formations with ultra-low permeability e.g. shales and roof-rocks.
This is how our HLT tool works.
The HLT tool will be positioned at the desired depth in the well, locked in place with two packers. The annulus pressure between the two packers is lowered by pumping out some of the drill fluid.
The annulus section is then allowed to repressurize to balance the reservoir pressure. A 24 mm diameter hole through the wall of the well will be drilled while the hole is flushed with oil carried inside the HLT from surface. When the hole has reached the desired depth (max 700 mm for this prototype) a slim (6 mm OD) probe is pushed through a hole in the drill-bit, lands on the fresh surface, connects with the water on the surface of the rock and the pressure of the water inside the reservoir is captured. The mini-drill string and the probe is retracted. Packers unset.
How much time is needed for the operation?
The HLT has been designed to perform this single depth measurement in less than four hours. Repeated measurement is possible. The speed of measurement is ensured by a fast pressure sensor (low compressibility system) and deliberate placement of the HLT in the well where the water saturation is not at its lowest.
Both the oil and water pressure is measured with a dual-purpose sensor (patent pending). The dual-purpose sensor removes uncertainty that would normally arise from using two sensors. The resulting pressure difference between water and oil will be estimated with better than 0.1 bar accuracy. This typically give an accuracy in the FWL estimate of better than 5 meters. The HLT can be used in producing fields to measure the remaining oil production potential.
The Hydrophilic technology
Our aim is to change everything.
