The paper use the AHP-DEA model to evaluate and analyze current situation influencing factors of rural ecological environment farmers with different livelihood strategies in 9 administrative villages 3 districts counties Three Gorges Reservoir area. conclusions are as follows: (1) deeper nonagricultural level, worse impact on environment, its status. However, degree employment is not only deter...

Petro physics, rock physics and multi-attribute analysis have been employed in an integrated approach to delineate porosity variation across Tamag Field of Niger Delta Basin. Gamma and resistivity logs were employed to identify sand bodies and correlated across the field. Petro physical analysis was undertaken. Rock physics modelling and multi-attribute analysis were carried out. Two hydrocarbo...

Well placement optimization is a very challenging problem due to the large number of decision variables involved and the nonlinearity of the reservoir response as well as of the well placement constraints. Over the years, a lot of research has been done on this problem, most of which using optimization routines coupled to reservoir simulation models. Despite all this research, there is still a ...

Accurate fault identification is essential for geological interpretation and reservoir exploitation. However, the unclear noisy composition of seismic data makes it difficult to identify complete structure using conventional methods. Thus, we have developed an attentional U-shaped network (EAResU-net) based on enhanced feature fusion automated end-to-end 3D data. EAResU-net uses mechanism reduc...

Grieve oil field, discovered in 1954, is located in southeastern Wind River Basin, central Wyoming. This Lower Cretaceous, valley-fill and channelized, Muddy sandstone reservoir is a stratigraphic/structural trap with an average structural dip of 15 degrees. Multiple recovery mechanisms have contributed to produce more than 30 million barrels of premium light sweet crude, including gas expansio...

Two reservoirs domiciled in a well have been analysed this study order to obtain the quantitative reservoir properties. These properties are essential not only for development and optimization but also accurate decision-making prior exploitation production. A suite of composite logs comprising caliper log, gamma-ray (GR) density resistivity sonic transit time obtained from field onshore Niger D...

In this study, oil production and retention were observed compared in 72 reservoir simulation cases, after which an economic analysis for various CO2 prices was performed. Reservoir cases comprise different combinations of water alternating gas (WAG) ratios, permeabilities, well distances. These models set at three depths; thus pressure temperature conditions, to see the impact miscibility on s...

The fate and transport of mercury are of critical concern in lowland floodplains and wetlands worldwide, especially those with a history of upstream mining that increases the mobility of both dissolved and sediment-bound Hg in watersheds. A mass budget of total mercury (THg) quantifies sources and storage for particular areas - knowledge that is required for understanding of management options ...
