NEOS Tech Series: Using Magnetic Data to Locate Abandoned Wellbores

The cultural grid is separated from the total magnetic intensity and then compared to mapped features, like wells and pipelines.

By: Maggie Baber, NEOS Geoscientist Magnetic interpretation is an integral component of NEOS’s multi-measurement interpretation methodology (MMI). Magnetic data measures changes in a rock’s magnetic susceptibility, or the degree of magnetization in response to earth’s magnetic field. Rocks or materials with high magnetite content have a high magnetic susceptibility. Magnetics, along with gravity and other …

NEOS Tech Series: Multi-Physics Reveals Basement Secrets

Magnetic data along the Mid-Atlantic Ridge

The NEOS MMI methodology, specifically with the use of potential methods, is greatly suited to provide understanding of the structural complexity of a basin, at the basement level. While gravity and magnetic methods use different rock properties (density vs. susceptibility), these methods are diagnostic and when taken together can eliminate many geologic alternative scenarios therefore …

NEOS Tech Series: Gravity & Magnetics

Grav&Mag

A multi-physics approach to geoscience allows NEOS to simultaneously interpret several possible geophysical measurements in order to uncover deeper insights into regional prospectivity and well productivity. While there may be potential for the inclusion of a number of measurements within an interpretation, each is equally unique and beneficial on its own accord. GRAVITY & MAGNETICS …

Why Acquire New Gravity & Magnetic Data?

Grav-Mag

We often get asked the question, “if I already have access to some public Grav-Mag data, why are you suggesting I spend more money to acquire a newer version of the ‘same’ data?” While it’s true that we’re dealing with the same measurements – gravity and magnetic – the quality and utility of the public data …

NEOS in New Technology Magazine

NewTechMagazine

The rush for unconventional oil and gas resources is increasing the level of hazards faced by producers in the field. Hazards and risks could include anything from long-abandoned wellbores to shallow gas pockets, unknown faults and fractures, and the natural seepage of hydrocarbons into groundwater that may be blamed on drilling operations at some future …

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 …

Marcellus Case Study – Tioga County, Pennsylvania

Resistivity voxel over an ~80 sqkm area of Tioga County, Pennsylvania. Top is ~500' subsurface while the bottome is ~10,000' subsurface. High resistivity intervals (subsurface gas plumes?) shown in hot colors. Surface oil seeps noted in green; surface gas plumes in pink.

In 2011, NEOS GeoSolutions kicked off its first-ever project in Appalachia – a combined neoBASIN survey over all of Tioga County, PA and a more focused neoPROSPECTOR survey covering an ~80 sqkm patch in the southwestern part of the county. The objectives were clearly laid out by the lead underwriter, a supermajor that had previously bought …

Insights Throughout the Geologic Column: Surface Applications

Tioga Plumes

In this, the fourth of a four-part series, we look at applications for multi-measurement methodologies on the surface. Although there are numerous MMI applications for surface investigation, the following come up most often in discussions with our clients: DHI (direct hydrocarbon indicator) and indirect hydrocarbon detection Airborne geo-botany & lithology Environmental baselining Legacy infrastructure detection …
