The paper presents a 3D sedimentological characterization of a delta plain reservoir. The analysis started with detailed core description studies focusing on the genetic interpretations of the sedimentary structures and multivariate statistical analyses (including Q-mode cluster and R-mode factor analysis), of the sporadic grain-size distributions. These results made the depositional processes ...

Zigzag ZnS thin films prepared by thermal evaporation method using glancing angle deposition (GLAD) technique. ZnS films with zigzag structure were produced at deposition angles of 0˚, 60˚ and 80˚ at room temperature on glass substrates. Surface morphology of the films w:as char:acterized by using field emission scanning electron microscopy (FESEM). The optical properties of the specimens were i...

for obtaining reservoir petrophysical properties, for example porosity, non-destructive methods such as x-ray computed tomography, ct, seems to be precise and accurate. porosity is deducted from the ct image with a single scan via different techniques, such as pore space detection by image segmentation techniques then correlation with porosity. more than one hundred samples with carbonate litho...

A mathematical model is developed describing the natural smoldering of logs. It is considered the steady onedimensional propagation of infinitesimally thin fronts of drying, pyrolysis, and char oxidation in a horizontal semi-infinite log. Expressions for the burn rates, distribution profiles of temperature, and positions of the drying, pyrolysis, and smoldering fronts are obtained in terms of t...

OBJECTIVE To investigate the ability of a portable, personal computer-driven, pupillometer to record the pupillary response curve during the swinging flashlight test. Also, to determine whether these response curves can be used to identify and quantify relative asymmetry in the pupillary light reflex between eyes in healthy volunteers with simulated afferent pupil defects (APDs) and patients wi...

 Abstract— A modified log domain decoding algorithm of Low density parity check (LDPC) codes over GF(q) using permutation to simplify the parity check equation is presented in this paper which is different from the conventional log domain decoding algorithm of Low Density Parity Check (LDPC) codes over GF(q) [11]. Modified Log domain is mathematically equivalent to the conventional log domain ...

A distributed neural network, running on a large transputer-based parallel computer, was trained to identify the presence of the main lithographical facies types in a particular oil well, using only the readings obtained by a log probe. The resulting trained network was then used to analyse a variety of other wells, and showed only a small decrease in accuracy of identiication. Geologists class...
