To better understand the pore structure and fractal character of lacustrine shales their influence on liquid hydrocarbon occurrences, in this study, a total 29 oil-bearing shale samples collected from Shahejie Formation Dongying Sag, Bohai Bay Basin, were investigated based nitrogen adsorption (NGA) analysis combined with TOC, Rock-Eval pyrolysis, X-ray diffraction (XRD), field emission-scannin...

We propose a new class of rigorous methods for derivative-free optimization with the aim delivering efficient and robust numerical performance functions all types, from smooth to non-smooth, under different noise regimes. To this end, we have developed methods, called Full-Low Evaluation organized around two main types iterations. The first iteration type (called Full-Eval) is expensive in func...

rock selection in modeling and simulation studies is usually based on two techniques; routinely defined rock types and those defined by special core analysis (scal). the challenge in utilizing these two techniques is that they are frequently assumed to be the same, but in practice, static rock-types (routinely defined) are not always representative of dynamic rock-types (scal defined) in the re...

Evidence of biochemical and geochemical evolution was sought in insoluble carbonaceous matter from 30 selected pre-Phanerozoic sediments ranging in age from about 3.8 to about 0.7 x 10(9) years. The carbon isotope ratios observed were in the range of -20 to -32 per mil with reference to the Peedee belemnite standard, similar to those previously reported. No systematic trends are obvious to us. ...

We present and prove properties of a new offline policy evaluator for an exploration learning setting which is superior to previous evaluators. In particular, it simultaneously and correctly incorporates techniques from importance weighting, doubly robust evaluation, and nonstationary policy evaluation approaches. In addition, our approach allows generating longer histories by careful control o...

The popularity of Big Data computing models like MapReduce has caused the emergence of many frameworks oriented to High Performance Computing (HPC) systems. The suitability of each one to a particular use case depends on its design and implementation, the underlying system resources and the type of application to be run. Therefore, the appropriate selection of one of these frameworks generally ...

Methane in source rocks may not exist exclusively as free gas. It could exist in equilibrium with carbon and higher hydrocarbons: CH4 + C < = > Hydrocarbon. Three lines of evidence support this possibility. 1) Shales ingest gas in amounts and selectivities consistent with gas-carbon equilibrium. There is a 50% increase in solid hydrocarbon mass when Fayetteville Shale is exposed to methane (450...

A comparative study of different species from the yeast genera Cyptococcus and Rhodotorula, isolated from rotted wood, was camed out using analytical pyrolysis-gas chromatography-mass spectrometry. The predominant compounds obtained were various alkanes, cyclic ketones, indolic compounds, alkanoic acids and furan derivatives, which are pyrolytic products of lipids, proteins and carbohydrates. T...

Through this project, we will explore Semantic Textual Similarity a shared task in Sem Eval 2012. The problem involves comparing a pair of sentences for semantic equivalence, reporting the equivalence on a scale of 0 5 with 0 meaning no equivalence and 5 meaning semantically equivalent. This task is more challenging than determining if the two sentences are paraphrases (a simple yes/no answer),...
