Origin of Flowback and Produced Waters from Sichuan Basin, China

Environmental Science & Technology, 2018
Shale gas extraction through hydraulic fracturing and horizontal drilling is increasing in China, particularly in Sichuan Basin. Production of unconventional shale gas with minimal environmental effects requires adequate management of wastewater from flowback and produced water (FP water) that is coextracted with natural gas.

Unexpected deep mixing layer in the Sichuan Basin, China

Atmospheric Research, 2021
Abstract In the Sichuan Basin (SCB), one of the four major basins in China, a one-year continuous observation study was performed using a ceilometer in Chengdu (2018.11–2019.12). The results show that the mixing layer height (MLH) in the SCB exhibits a bimodal seasonal variation pattern, with peaks in June (842 m) and October (704 m) and valleys in ...

Shale Gas-in-Place Calculation from Sichuan Basin, China

Advanced Materials Research, 2013
The methods of shale gas content measurement and shale Gas-in-place calculation are introduced in detail. The shale gas content is form 1.05 to 1.84 m3/t. From Gas-in-place calculation the adsorption gas content is a little more than free gas content. The advantage of shale gas accumulation areas are high formation pressure, low water saturation, high ...

XuJiahe Formation Petroleum System in Central Sichuan basin, China

International Petroleum Technology Conference, 2013
Abstract The Golden Autumn Tight Gas Block is located in the northwest of the Central Sichuan Basin and covers an area of 4,067 km2. Shell, in partnership with PetroChina, has been appraising the gas potential of the area since 2010.

Helium signatures of gases from the Sichuan Basin, China

Organic Geochemistry, 2014
Abstract Natural gases from the Sichuan Basin, China were analyzed to investigate helium abundances and isotopic composition in order to assess crustal vs. mantle inputs into the Sinian to Jurassic gas reservoirs that occur at depths up to 4900 m. In general, gases from the Sinian and pre-Sinian strata in south Sichuan have relatively high abundances

Lower Cretaceous paleosols and paleoclimate in Sichuan Basin, China

Cretaceous Research, 2016
Abstract Abundant Lower Cretaceous (Berriasian–Hauterivian) paleosols have been recognized in the Sichuan Basin, along with the preserved pedogenetic features, e.g., soil horizons, soil structure, root traces and pedogenic nodules. Chemical, geochemical and mineralogical analyses were used to examine the paleosols.

Algae Beach Dolomite Reservoir Prediction in Sichuan Basin, China

81st EAGE Conference and Exhibition 2019, 2019
Summary The algae beach dolomite reservoir, with great exploration potential, is widespread developed in the study area, which is located in the northwest of Sichuan Basin. The reservoir of Triassic Leikoupo formation is strong heterogeneity, and the lateral distribution is discontinuous.

Sedimentary charateristics and hydrocarbon accumulation in Northeast Sichuan basin

Frontiers of Earth Science in China, 2008
Northeast Sichuan basin is a Mesozoic-Cenozoic basin in the northern margin of the Yangtze plate which has a complex tectonic background and hydrocarbon accumulation history. By means of the analysis method of wave processes, major cycles of sedimentary wave process in this basin have been studied.

Paleozoic shale gas resources in the Sichuan Basin, China

AAPG Bulletin, 2018
The Sichuan Basin, China, is commonly considered to contain the world’s most abundant shale gas resources. Although its Paleozoic marine shales share many basic characteristics with successful United States gas shales, numerous geologic uncertainties exist, and Sichuan Basin shale gas production is nascent.

ACHIEVEMENTS IN THE DEVELOPMENT OF DEEP DRILLING TECHNIQUE IN SICHUAN BASIN

Proceedings of International Meeting on Petroleum Engineering, 1988
ABSTRACT Sichuan basin is the primary carbonate deposition basin in China, which is rich in natural oil and gas resources and has a very long drilling history. The geological conditions in the basin are very complex, which causes a lot of difficulties in deep drilling.
