High-Speed NMR Logging
Identify hydrocarbons in low-contrast, low-resistivity pay zones
The high-resolution CMR-Plus combinable magnetic resonance tool with high-logging-speed capability enhances the precision of your nuclear magnetic resonance (NMR) logging.
Get answers on reservoir permeability, water cut ,and hydrocarbon pore volume at logging speeds 3 to 5 times faster than those of traditional NMR tools. These answers are invaluable to the initial evaluation of the reservoir. Also, this information advances your completion designs so you can improve well performance and return on investment.
Evaluate porosity and permeability of thin pay sandsAdditional technology gives you estimates of bound fluid, free fluid, and total porosity for evaluate producibility, especially in thinly laminated formations.
Decrease operating timeTechnology continually prepares the formation ahead of the antenna for the next measurement cycle. CMR-Plus logging is at speeds as high as 2,700 ft/h.
In one well, the porosity in the sands was consistently 36% to 38%, but the grain size and the permeability changed from sand to sand. The CMR-Plus tool logged a 1,000-ft section in this well in a little over an hour, saving 4 h of rig time while revealing the previously unknown variability in grain size and permeability.
