Sedimentary environment and organic matter enrichment of the Lower Cambrian Niutitang Formation shale, western Hunan Province, China

open access: yesShiyou shiyan dizhi, 2021
The Lower Cambrian Niutitang Formation shale is an extremely crucial marine source rock developed at the mid-upper Yangtze block of China. To clarify the paleoenvironment and conditions which are responsible for organic matter enrichment of the Niutitang

Reconstruction of paleo-temperature and pressure of oil reservoirs based on PVTx simulation: problems, strategies and case studies

open access: yesShiyou shiyan dizhi, 2021
The PVTx simulation of fluid inclusions is a valuable method for the reconstruction of paleo-temperature and pressure of oil reservoir. Since the accurate composition of oil-bearing inclusion is very difficult to be obtained and the composition may be ...

Review on molecular structures of asphaltene macromolecules and instrumental analytical approaches

open access: yesShiyou shiyan dizhi, 2023
As one of the major fractions of petroleum and/or source rock extracts, asphaltene is commonly characte-rized by complicate molecular structures as well as relatively higher molecular weight (MW).

Entropy Accumulation [PDF]

open access: yesCommunications in Mathematical Physics, 2020
AbstractWe ask the question whether entropy accumulates, in the sense that the operationally relevant total uncertainty about an n-partite system $$A = (A_1, \ldots A_n)$$ A = ( A 1 , … A n ) corresponds to the sum of the entropies of its parts $$A_i$$ A i .

Accumulate-repeat-accumulate-accumulate-codes [PDF]

open access: yesIEEE 60th Vehicular Technology Conference, 2004. VTC2004-Fall. 2004, 2005
Inspired by recently proposed accumulate-repeat-accumulate (ARA) codes (Abbasfar et al. (2004)), in this paper we propose a channel coding scheme called accumulate-repeat-accumulate-accumulate (ARAA) codes. These codes can he seen as serial turbo-like codes or as a subclass of low density parity check (LDPC) codes, and they have a projected graph or ...

Maturity limit of sweet spot area for continental matrix type shale oil: a case study of lower Es3 and upper Es4 sub-members in Dongying Sag, Bohai Bay Basin

open access: yesShiyou shiyan dizhi, 2021
The matrix type shale oil will become the main contributer for increasing shale oil reserves and production in China. Maturity is an important factor for the controlling to the distribution of sweet spot area for matrix type shale oil.
