Magnetic resonance imaging logging-while-drilling service

Source-less porosity to assess reservoir quality

The nuclear magnetic resonance measurements provided by the range of MRIL®-WD™ sensors enable early identification of critical petrophysical parameters by differentiating between moveable and bound fluids to deliver comprehensive formation evaluation. A real-time assessment of reservoir quality is achieved through a mineralogy-independent measurement of total porosity and the fractionalized porosities of microporosity, total bound fluid volume and moveable fluid volume, along with a continuous permeability estimate.

The MRIL-WD service provides viable source-less porosity answers, while also providing reservoir quality assessments in thin-bed reservoirs and low-resistivity contrast reservoirs.

Features

T1 acquisition measurement provides a lateral motion-tolerant method, with minimal pre-job planning
T2 acquisition method while wiping or sliding, with fluid typing using dual wait time or dual echo spacing
Wide range of tool sizes and stabilizer options enables logging reservoirs in multiple hole sizes

Drill to produce

Increase the potential success in finding producible oil and gas while avoiding water production through real-time evaluation of the formation properties
Highlight reservoir “sweet spots” by identifying geosteering targets to help optimize production when combined with the GeoTap® and GeoTap IDS services

Enhance reservoir understanding

Identify reservoir zones often missed by conventional log data
Identify total porosity and moveable fluid, providing real-time assessments of reservoir quality with minimum impact from invasion

Reduce well time

Provide mineralogy-independent porosity assessments, removing environmental risks often associated with nuclear sources
Obtain fundamental petrophysical parameters without the cost, risk, and rig time associated with Wireline services
Identify reservoir zones with moveable fluid and permeability to optimize the formation pressure testing and sampling program
