Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NMR technology lacks the ability to detect oil and gas reservoirs, faults, and differentiate them from free radicals from the surface, limiting its predictive power and exploration efficiency in the petroleum industry.
Innovation Solution
A method utilizing a standardized NMR apparatus with a specimen of known oil composition, scanning perpendicular to the earth's surface to determine the presence of oil and gas reservoirs by analyzing precession values, porosity, and permeability, while also detecting faults and free radicals through inverse oscillation and molecular fingerprint analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional NMR technology is used for down hole logging, then properties of live oil and wettability of oil formations can be determined after drilling, but the predictive power for detecting oil and gas reservoirs from the surface is lost
Solution Approach 1:
The patent inverts the conventional NMR approach by performing detection from the surface rather than from down hole positions. The standardized NMR apparatus with specimen cell is positioned at the surface and oriented perpendicular to the earth's surface, allowing non-invasive detection of subsurface oil and gas reservoirs without requiring borehole access.
Solution Approach 2:
The patent enables preliminary detection and mapping of oil and gas reservoirs, faults, and free radicals before drilling operations begin. By scanning the area with the standardized NMR apparatus and analyzing precession values, porosity, and permeability, the system provides predictive information that guides subsequent drilling decisions and reduces dry hole risks.
2Productivity
If NMR scanning is performed to detect oil and gas reservoirs, then predictive power and exploration efficiency are improved, but the ability to differentiate from free radicals and faults is reduced
Solution Approach 1:
The patent assigns different evaluation criteria to different detection targets. Oil and gas reservoirs are identified by specific precession values within certain ranges, faults are detected through inverse oscillation patterns, and free radicals are identified by high energy level readings. This localized quality assessment for each target type enables accurate differentiation despite using the same NMR apparatus.
Solution Approach 2:
The patent utilizes multiple NMR parameters to differentiate between targets: precession values for reservoir detection, inverse oscillation characteristics for fault identification, and energy level readings for free radical detection. By monitoring changes in these different parameters simultaneously, the system can distinguish between oil and gas reservoirs, faults, and free radicals with high precision.
3Measurement precision
If standardized NMR apparatus is used with specimen cell orientation, then detection of reservoir properties is enabled, but interference from ground sediments and fluids increases
Solution Approach 1:
The patent introduces a standardized specimen cell containing known oil composition as an intermediary between the NMR apparatus and the subsurface targets. This specimen cell is oriented perpendicular to the earth's surface during scanning, serving as a reference that enhances the detection of reservoir properties while filtering out interference from ground sediments and fluids through standardized measurement protocols.

Implementation Method 1
Nuclear Magnetic Resonance (NMR) is a phenomenon which occurs when nuclei of certain atoms, molecules, and/or molecular compounds are exposed to a second oscillating field at vector, resulting in measurable quantum properties of the subject(s) being introduced to said field.
Implementation Method 2
scanning at or near the surface of the earth with said standardized cell containing said specimen until said standardized cell precesses
Implementation Method 3
The step of detecting and locating all faults comprises the step of observing inverse oscillation of the standardized cell containing the oil specimen as it is passed over the earth
