Methods for creating a critical crust reservoir model
12298458 · 2025-05-13 · ·

Provided herein are systems and methods for generating reservoir models including the SOC nature of the Earth's crust. The methods employ seismic emission tomography (SET) to generate three dimensional models of a formation providing permeability without the need for traditional reservoir modeling techniques and allowing for the identification of naturally-occurring permeability pathways that provide accurate and precise locations for the efficient recovery of hydrocarbons or other fluids.

DEVICE FOR CHARACTERIZING AND TESTING ON-SITE BASIC PARAMETER OF NATURAL GAS HYDRATE

A device for characterizing and testing on-site basic parameter of a natural gas hydrate includes a servo transmission mechanism, a pressure-resistant manipulator, a sealing mechanism, a data acquisition system, a resistivity testing system, an outlet metering system and an undisturbed permeability testing module; the undisturbed permeability testing module is used for testing a permeability of a hydrate sample subjected to sample transfer; the pressurizing system is used for adjusting a pressure of each point in the device; the servo transmission mechanism includes a pressure-resistant sample transfer manipulator and a servo driver; the servo driver is used for driving the pressure-resistant sample transfer manipulator to reciprocating motion, and the pressure-resistant sample transfer manipulator is used for separating the sample to be tested from the sheath under a pressure and pushing the sample into a holder; and the resistivity testing system is used for detecting a resistivity value.
