Understanding fluid storage and flow potential 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, and the geometry of the pores containing these fluids, providing information on both storage and flow potential.
Not only does BMR provide 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 that is bound in place in the rock.
Where more than one fluid type is present – such as in oil and gas or 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 derived, 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 & gas applications.
The QL40 BMR tool family is compatible with the ALT/Mount Sopris Instruments Quick Link (QL) product line and can be combined with other QL40 tools as part of a larger tool string, or they can be run as standalone logging tools.
The tools run on standard 4-core cable and use the ALT Logger or the newer OPAL acquisition systems. Two tool types are currently available:
Qteq’s BMR logging technology can be accessed through our wireline partners in the following areas:
