Generalised Entropy Accumulation

Communications in Mathematical Physics, 2022
AbstractConsider a sequential process in which each step outputs a system $$A_i$$ A i and updates a side information register E. We prove that if this process satisfies a natural “non-signalling” condition between past outputs and future side information, the

Hydrocarbon accumulation process, and effective natural gas accumulation in Permian Changxing Formation, southeastern Sichuan Basin

Shiyou shiyan dizhi
The Permian Changxing Formation in the southeastern Sichuan Basin has complex natural gas accumulation patterns. Using analysis methods such as thermal evolution history reconstruction, rock thin sections, mineral isotopes, and fluid inclusions, this ...

Combination of alkali–surfactant–polymer​ flooding and horizontal wells to maximize the oil recovery for high water cut oil reservoir

Energy Reports, 2021
Alkali/surfactant/polymer (ASP) combines the advantages of each of the chemical in the blend. ASP has shown to be an effective and practical method to enhance oil recovery.

Geochemical evidence of paleo-depositional environment of Triassic Adula Formation source rocks of eastern Qiangtang Basin

Shiyou shiyan dizhi
The mudstone within the Upper Triassic Adula Formation constitutes a crucial hydrocarbon source rock reservoir in the Qiangtang Basin, yet there is considerable debate regarding its paleo-depositional environment.

Helium accumulation characteristics and main controlling factors of helium depletion in Daniudi Gas Field, Ordos Basin

Shiyou shiyan dizhi
A certain amount of helium is found in the natural gas of both the Dongsheng and Daniudi gas fields in the Hangjinqi area of the Ordos Basin. However, the average helium content in the Daniudi Gas Field is only about one-fourth of that in the Dongsheng ...

accuMUlate: a mutation caller designed for mutation accumulation experiments [PDF]

Bioinformatics, 2017
Abstract Summary Mutation accumulation (MA) is the most widely used method for directly studying the effects of mutation. By sequencing whole genomes from MA lines, researchers can directly study the rate and molecular spectra of spontaneous mutations and use these results to understand how ...

Pore types, genesis, and evolution model of lacustrine oil-prone shale: a case study of the Cretaceous Qingshankou Formation, Songliao Basin, NE China

Scientific Reports, 2022
A comprehensive characterisation of the pore structure in shale oil reservoirs is essential for forecasting oil production and exploration risks. This study forecasted these risks in the oil-rich Songliao Basin using combination of high-resolution field ...

Accumulation Analysis.

, 2022
A typestate specification indicates which behaviors of an object are permitted in each of the object’s states. In the general case, soundly checking a typestate specification requires precise information about aliasing (i.e., an alias or pointer analysis), which is computationally expensive. This requirement has hindered the adoption of sound typestate
