In situ stress field inversion and its application in mining-induced rock mass movement

International Journal of Rock Mechanics and Minings Sciences, 2012
Abstract Based on a series of experiments in numerical simulation, the model boundary conditions for in situ stress field inversion and excavation are discussed. Study results indicate that roller boundary conditions are reasonable for the in situ stress field inversion before excavation simulation, while, as a closed system, changing the roller ...

Modified Inversion Technique for Determining the In-situ Stress Field

SPE Western Regional & AAPG Pacific Section Meeting 2013 Joint Technical Conference, 2013
Abstract One of the major challenges of oil industry is to predict the in-situ stress field accurately. Accordingly, different techniques have been developed to predict the reservoir stress field in the past decades. Inversion Technique is a powerful method which was developed to determine the minimum and maximum horizontal stress ...

Autonomous Inversion of in Situ Deformation Measurement Data for Injection-Induced Stress Change

57th U.S. Rock Mechanics/Geomechanics Symposium, 2023
ABSTRACT Geologic carbon storage (GCS) is likely to play a key part of the global effort to dramatically reduce CO2 emissions and perhaps even reduce atmospheric CO2 concentrations through carbon negative operations.

Inversion of fractures with combination of production performance and in-situ stress analysis data

Journal of Natural Gas Science and Engineering, 2017
Abstract Successful identification of the fractures in fractured reservoirs is important to guarantee an effective development. Considering that the production performance of fractured reservoirs contains important information of the distribution of fractures, the production performance can be applied for the inversion of fractures.

Inversion Technique To Determine the In-Situ, Stress Field From Fracturing Data

Proceedings of SPE Annual Technical Conference and Exhibition, 1988
ABSTRACTTypically one assumes that the two horizontal in-situ stresses are equal in borehole stability studies. This simplification has been necessary due to lack of information. The new method presented here distinguishes between the in-situ stresses and estimates the magnitude and the direction of each of the two horizontal in-situ stresses.

Iterative joint inversion of in-situ stress state along Simeulue-Nias Island

AIP Conference Proceedings, 2017
In-situ stress inversion from focal mechanisms requires knowledge of which of the two nodal planes is the fault. This is challenging, in particular, because of the inherent ambiguity of focal mechanisms the fault and the auxiliary nodal plane could not be distinguished.
