Dynamic Reserve New Calculation Model for Fracture-Vuggy Reservoirs Considering the Effect of Dissolved Gas Precipitation

open access: yesCejing jishu
The internal spatial structure of fractured-karst reservoirs is complex, and the fluid distribution forms are diverse. The existence of water bodies and dissolved gases in the fracture-karst reservoir collective has a significant impact on dynamic ...

A Lagrangian approach to modeling heat flux driven close-contact melting

open access: yes, 2017
Close-contact melting refers to the process of a heat source melting its way into a phase-change material. Of special interest is the close-contact melting velocity, or more specifically the relative velocity between the heat source and the phase-change ...

56Ni dredge-up in Supernova 1987A [PDF]

open access: yes, 1998
We use early-time observations of He I 10830 \AA to measure the extent of upward mixing of radioactive material in SN 1987A. This work develops and extends the work of Graham (1988), and places constraints on actual explosion models.

Material balancing—a generalized solution method

open access: yesApplied Mathematical Modelling, 1989
Abstract A method for the solution of material balancing problems encountered in mineral processing is described. The method makes use of the highly structured nature of the equations encountered, thus resulting in savings in computer storage space and computation time.

Determination of dynamic reserves of fractured horizontal wells in tight oil reservoirs by multi-region material balance method

open access: yesPetroleum Exploration and Development, 2016
To overcome the deficiencies of the material balance method, according to strong heterogeneity of tight oil reservoirs, the flow region of fractured horizontal well is divided into high permeable zone and low permeable zone, which are equivalent to ...

Evaluasi Isi Awal Gas Di Tempat Dan Analisis Decline Curve Pada Reservoir Ys [PDF]

open access: yes, 2019
YS reservoir has data of gas initial in place (GIIP) with a volumetric method of 3,476 Bscf. Because of improvement of data, GIIP can be evaluated using material balance method. Then the production of wet gas will be forcasted until below economic limit.
