White Paper: Multi-Measurement Interpretation in Action

MMI White Paper Cover

NEOS has recently published a comprehensive white paper on the technologies and methodologies that form the foundation for Multi-Measurement Interpretation (MMI). Previously available only to NEOS clients, the white paper highlights MMI applications from the basement to the surface, in conventional and unconventional shale plays, and in both regional reconnaissance and pre-drill assurance situations. The MMI …

For Me, EM Resistivity is the Key

Resistivity Variations `1,000 ft Sub-surface in Tioga County, PA. Hot colors represent highly resistive intervals (potentially shallow-gas geohazards). Black polygon is ~ 80sqkm.

NEOS is all about objectivity. About being a dispassionate analyst of G&G measurements and going “wherever the data takes us.” In such an environment, I suppose one shouldn’t play favorites. But I can’t help it. I do have a favorite measurement – EM (Electro-Magnetic), especially as used for resistivity mapping. Now that might be a …

Explore with More: Powder River Basin, Wyoming


The U.S. Geological Survey (USGS) estimates that the Powder River Basin (PRB) contains approximately 1 billion BOE of remaining recoverable oil and 15 TCF (2.5 billion BOE) of remaining recoverable natural gas. Forty percent of the liquid hydrocarbons are believed to be contained in two unconventional shales – the Mowry and the Niobrara – while …

The Geomechanics of Hydraulic Fracturing

Halliburton Fracturing

I had the good fortune to be on ‘The Farm’ this week, where I had an opportunity to listen to a fascinating presentation by Stanford Professor Mark Zoback. Mark is a recognized expert in earthquakes. One of his initial claims to fame resulted from his multi-year study of the San Andreas fault. Whenever there is …

Thinking About Geothermal? Think About NEOS.

Brawley & San Andreas

I saw an interesting report today from MIT on The Future of Geothermal Energy in the U.S. It got me thinking back to the first ‘real job’ I ever had – in UNOCAL’s Geothermal Division. Our petroleum engineering curriculum required sophomores to work as roustabouts, the theory being that exposure to ‘real work’ (and real …

Fracture Detection Using a Multi-measurement Methodology


Although Colorado’s Piceance Basin contains natural gas, coal, and oil shale, the natural gas-bearing reservoirs of the Cretaceous Williams Fork Formation have been the main focus of development activity. The Williams Fork consists of several thousand feet of shale, sandstone, and coal that were deposited in a coastal plain environment. The formation has long been …
