Despite exploration and production success in Niger Delta, several failed wells have been
encountered due to overpressures. Hence, it is very essential to understand the spatial …

The global energy scenario is undergoing an unprecedented transition. In the wake of
enormous challenges, such as increased population, higher energy demands, increasing …

Precise pore pressure estimation has high significance in terms of drilling and development
operations. Regarding its necessity, empirical and intelligence methods have been …

Wellbore instability is one of the most critical challenges during drilling, which may result in
complex problems such as stuck pipe, high torque and mud loss, impeding the drilling …

Porosity is a key variable for hydrocarbon reservoirs evaluation. It can be directly determined
in laboratory tests using core samples or calculated indirectly from well logs. However, these …

Determination of the rock elastic parameters is essential in geomechanical studies. Among
the elastic parameters, Young's modulus (YM) and Poisson's ratio (PR) have many …

The prediction of continued profile for static Poisson's ratio is quite expensive and requires
huge experimental works, and the discontinuity in the measurement and the limited …

The least principal stresses of downhole formations include minimum horizontal stress
(σmin) and maximum horizontal stress (σmax). σmin and σmax are substantial parameters …

The optimum performance of various subsurface operations such as stimulation treatments,
wellbore drilling, horizontal well placement, underground mining, and tunneling rely on …

Geomechanical properties of rocks are the basic requirements for the construction of civil
structures. In the present study, a new relationship between static elastic modulus (Es) and …
