A generic multistage compartmental model for interpreting gas production profiles [PDF]

open access: yes, 2010
The gas production technique has become a key tool in feed evaluation and rumen fermentation studies. The value of the technique relies on modelling experimental data to obtain estimates of rumen degradation parameters.

Full-cycle prediction of gas production variations in gas wells using different production methods [PDF]

open access: yesE3S Web of Conferences
Gas production from gas wells is affected by formation pressure and wellbore outflow during gas production. To increase the daily gas production and obtain smooth and efficient gas production gas wells, methods such as wellbore shut-in pressure recovery ...

Estimation of time of peak gas production in coalbed methane wells using production data analysis [PDF]

open access: yes, 2015
For coalbed methane (CBM) wells with rising gas production, time to reach peak of gas production and peak gas rate are two fundamental features of a production profile. This paper investigates the time of occurrence of peak of gas production in CBM wells

Plasma-chemical treatment of hydrogen sulfide in natural gas processing. Final report, May 1991--December 1992 [PDF]

open access: yes, 1993
A new process for the treatment of hydrogen sulfide waste that uses microwave plasma-chemical technology has been under development in Russia and the United States. Whereas the present waste-treatment technology, at best, only recovers sulfur, this novel

Stimulation technologies for Longwangmiao Fm gas reservoirs in the Sichuan Basin and their application results

open access: yesNatural Gas Industry B, 2014
The Longwangmiao Fm group gas reservoirs in the Moxi structure in central Sichuan Basin feature high temperature, high pressure and high H2S content. The thickness of such high permeable reservoirs with great homogeneity is a geologic basis for a high ...

Microscopic occurrence characteristics and seepage law of water bodies in gas reservoir under stress: a case study of tight reservoirs in the eighth member of Permian Shihezi Formation, Shenmu Gas Field, Ordos Basin

open access: yesShiyou shiyan dizhi, 2023
In order to solve the problem that the pore structure and the microscopic occurrence characteristics of fluid change with stress in real time during the depletion development of tight gas reservoirs, the pore structure, water production and irreducible ...

Shale Gas Production in the USA

open access: yes, 2016
The interest to assessing the shale gas resources in the USA has increased at the turn of the twentieth to twenty-first centuries. The success of the US oil and gas companies in commercial scale production spurred the efforts on verification of the data about the available shale gas resources. The shale gas production has created a surge in development

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
