New Variable Compliance Method for Estimating In-Situ Stress and Leak-Off from DFIT Data

, 2017
It is shown that using Carter leak-off is an oversimplification that leads to significant errors in the interpretation of DFIT data. Most importantly, this article reveals that previous methods of estimating minimum in-situ stress often lead to ...

Early identification on failure mode of loess landslide: insight from case study and physical model experiment

Frontiers in Earth Science
IntroductionThe Loess Plateau has long been plagued by cascading loess landslides. The rapid identification of these landslides, along with the accurate determination of their failure modes, is essential for conducting precise disaster assessments in the

Characteristics of in situ stress of tight oil reservoirs and its influence on petrophysical properties: a case study of Upper Triassic Yanchang Formation in Ordos Basin

Shiyou shiyan dizhi, 2021
The petrophysical properties of tight reservoirs and the state of fluid occurrence are affected by current geostress. In the past, there were few studies on the rock mechanical properties and in situ stress of the Yanchang Formation in the central and ...

In-situ stress characteristics and rockburst prediction for a tunnel in a high in-situ stress environment

Frontiers in Earth Science
As the main source of pressure around tunnel rock masses, in-situ stress must be thoroughly understood to accurately predict the potential for rockburst events, especially in high-stress construction environments.

In situ stress state in Mainland China [PDF]

pure and applied geophysics, 1995
In situ stress measurements are one of the important methods for studying the recent tectonic stress field and stress state. In this paper, the stress state and variation of stresses with depth in Mainland China are presented and analyzed on the basis of in situ stress data measured by both hydrofracturing and overcoring techniques.

In-situ stress analysis in the Chang 7 reservoir of northern Shannxi region

Unconventional Resources
The Shaanbei Chang 7 shale oil reservoir in the Ordos Basin develops vertically with multiple lithologic superimpositions. The interlayer stress of sand-mud-shale thin interbeds is different, and the stress within the small layer is variable, resulting ...
