Finally, the effect of porosity and saturation, two of the most important parameters that play a role...

... of pattern recognition. There are several intermediate results from calculations leading to the compressibilities mentioned above. These include process speed (ratio of permeability and porosity), pore throat aperture in microns at 35 percent cumulative pore volume ( r p35 ), water saturation ( S w...

... Our study field is located in the north of the state of Veracruz and east of the state of Puebla, in Mexico, Fig. 3 . The field was discovered in 1926. Due to petrophysical characteristics that present low porosities (Pore < 12 %), low permeabilities (absolute permeability < 1 mD) and high...

... Abstract A method is presented for incorporating Biot poroelastic coefficient on Pickett plots. The method allows integration of petrophysical parameters such as water saturation, porosity and permeability with geomechanics through Biot coefficient. Pattern recognition in Pickett plots have...

... in process speed (the ratio of permeability and porosity, Aguilera, 2014 ), there is also a continuum of pore throat apertures of different sizes, natural fractures with different apertures, and Biot coefficients for different rocks. All of these directly or indirectly which affect reservoir performance...

... Abstract A Pickett plot is a powerful graphical technique for petrophysical analysis of well logs, which was developed initially to represent Archie's equation visually. Pickett plots rely on pattern recognition on a log-log scale observable on a set of porosities and the corresponding true...

... interpretation and evaluation in the oil and gas industry has increased in recent decades, especially in Brazil, where the use of this technology was increased by more than 400% from 2011 to 2018 (from 49 to 208 runs). This increased usaged occurred mainly because the porosity estimation provided...

We concluded that dual porosity modeling of the fractures offered an acceptable balance between computational overhead, absolute accuracy and flexibility. The main parameters adjusted to achieve the history match were...

The complete evaluation methodology has 4 phases: 1) petrophysical evaluation, that includes multimineral evaluation, porosity estimation and calibration with mineralogical analysis; 2) TOC content evaluation, that includes...

... is necessary for the economic assessment of CO 2 EOR, and for the evaluation of carbon sequestration capacity. We measured the porosity, the rock compressibility and the CO 2 sorption in sidewall core plugs taken from two wells drilled in the Wolfcamp shale. Computed tomography scanning technology was used...

... Abstract The objective of this study is to present methods for calculating organic and inorganic porosities in shale oil reservoirs. This is achieved by combining density, neutron and NMR logs as well as laboratory geochemical and synthetic geochemical properties of organic matter. The study...

As a result, estimates of not only static parameters like porosity and saturation, but also dynamic parameters such as compressibility and permeability have been challenging. Historically this led...
