Efforts towards producing low-carbon fossil fuels and renewable energy resources have
increased significantly within the last two decades and are expected to grow even more in …

The mechanical properties of bedding planes in laminated shale rocks have attracted great
attention especially when assessing borehole stability. However, the anisotropic …

Uniaxial models are commonly used to describe the change in magnitude of horizontal
principal stresses in depleted reservoirs and consequently to analyze the stability of infill …

Borehole instability was frequently encountered during shale gas drilling. Most conventional
models are not applicable to layered formation's wellbore stability analysis on account of …

The primary objective of this paper is to propose a method for predicting the safe mud weight
window within the Bozi gas field situated in the Tarim Basin and establish a 3D wellbore …

The shale gas in Jingmen area in China has unique features different from North America
shale plays, such as abundant natural fracture corridors with complex patterns and …

The success of hydrocarbon recovery from the subsurface relies on wellbore stability usually
provided by suitable mud-weight. Too low can cause breakout and wellbore collapse; too …

Abstract Brownfield in Balingian and Baram Delta have handful of idle wells and well to be
abandoned in their inventories. The project aims to reduce the idle well inventories and …

Deep formation rich in the weak plane (bedding, micro-fractures) has strong strength
anisotropy and is the internal control factor of frequent wellbore instability of the long …

Understanding the effect of in-situ stresses on geological formations has been modeled over
the years aiming to evaluate their behavior in zones of interest. The relationship between …
