Reservoir evaluation of 8 wells in the Palaeozoic of the Irish Sea area : petrophysical interpretations of clay volume, porosity and permeability estimations [PDF]

, 2016
This report details the reservoir evaluation of 8 wells across the Palaeozoic (Carboniferous and Permian age) rocks of the UK Irish Sea for the 21CXRM Palaeozoic project.

Evaluation of mineralogy per geological layers by Approximate Bayesian Computation

, 2019
We propose a new methodology to perform mineralogic inversion from wellbore logs based on a Bayesian linear regression model. Our method essentially relies on three steps.

Combined Effect of the Microstructure and Mechanical Behavior of Lateritic Soils in the Instability of a Road Cut Slope in Rwanda

GeoHazards
A very common hazard in Rwanda is represented by the instability of steep road cut slopes in lateritic soil. In its natural state, this material appears as a fine-grained weak and altered rock, generally in unsaturated conditions.

Visualizing multiphase flow and trapped fluid configurations in a model three-dimensional porous medium

, 2013
We report an approach to fully visualize the flow of two immiscible fluids through a model three-dimensional (3D) porous medium at pore-scale resolution.

Interpreter of user programs for petrophysical parameters calculation

Revista Cubana de Ciencias Informáticas, 2014
Determining the volume of oil that can be extracted for a given well is vital for the oil industry. In the petrophysical evaluation of training set are used : data taken directly in the well using geophysical logs and process applications that allow ...

A new approach in rock-typing, documented by a case study of layer-cake reservoirs in field

Carnets de Géologie, 2003
In carbonate reservoirs, the relationship between porosity Ø, a measure of the combined volumes of several kinds of pore space (e.g. interparticle and separate-vug), and permeability K are neither linear nor logarithmic, hence only weakly correlatable ...

Expedition 362 Preliminary Report: Sumatra Subduction Zone [PDF]

, 2017
Drilling the input materials of the north Sumatran subduction zone, part of the 5000 km long Sunda subduction zone system and the origin of the Mw ~9.2 earthquake and tsunami that devastated coastal communities around the Indian Ocean in 2004, was ...

Evaluation of Shale Effect on Saturation Exponent from Well Logs in an Offshore Field, Niger Delta. [PDF]

, 2010
Hydrocarbon recovery is subject to various elements set to validate not only the availability of the type of fluid present at the subsurface, but also how saturated is the host rock with the fluid.

Geological structure, lithological and petrophysical properties of Neft Daşlari deposit: patterns of changes in the reservoir properties of productive strata depending on the depth of their occurrence (northwestern part of the South Caspian depression)

Известия высших учебных заведений: Геология и разведка
Background. In this article, we investigate geological, geophysical, and physical aspects that affect the reservoir capacity of oil, gas, and gas condensate fields in the area of the Neft Daşları deposit.   Aim.
