Near wellbore failure during the exploration of hydrocarbon reservoirs presents a serious
concern to the oil and gas industry. To predict the probability of these undesirable …

Rock elastic properties such as Poisson's ratio influence wellbore stability, in-situ stresses
estimation, drilling performance, and hydraulic fracturing design. Conventionally, Poisson's …

In this study, we used artificial neural networks (ANN) to estimate static Young's modulus
(Estatic) for sandstone formation from conventional well logs. ANN design parameters were …

Rock geomechanical properties impact wellbore stability, drilling performance, estimation of
in situ stresses, and design of hydraulic fracturing. One of these properties is Poisson's ratio …

Drilling depleted and ultra-deep gas reservoirs required special drilling fluids which should
be capable of bridging along the walls of the well and withstands a high differential …

Oil and gas operating companies are always concerned with evaluating the reserve of their
assets. Evaluation process of hydrocarbon reserves requires a full understanding and …

Determination of the formation tops is an important and critical parameter while drilling a
hydrocarbon well since it is one of the main factors affecting selection of the casing setting …

Static Poisson's ratio (ν s) is crucial for determining geomechanical properties in petroleum
applications, namely sand production. Some models have been used to predict ν s; …

During drilling the oil and gas wells, the drilling fluid is used for many purposes in the drilling
operations. The mud filtrate might invade the formation, and as a result, alterations will occur …

The experimental Poisson's ratio prediction is time-consuming and expensive and resulted
in discontinuous profile. Besides, the limited applicability of the existing empirical …
