An Optimization Method for Distributing Emergency Materials Which Balances Multiple Decision Criteria

open access: yesProcesses, 2022
In emergency rescue operations, it is very important for emergency management to arrange emergency materials scientifically and reasonably according to emergency needs. However, the decision criteria for emergency material distribution are often diverse, coupled with the lack of information acquisition due to the suddenness and development complexity ...

Calculation Model of Drainage Radius of Single-Layer/Multi-Layer Commingled Gas Production Wells in a Closed Constant-Volume Gas Reservoir and Its Application

open access: yesApplied Sciences
Gas drainage radius is the most important parameter for determining reasonable well spacing. However, the drainage radius of both single-layer and multi-layer commingled gas production wells cannot be directly obtained through reservoir well tests.

Modelling of oil water contact by method of material balance

open access: yesИнтерэкспо Гео-Сибирь, 2010
A simple model used for calculation of current oil water contact by simply manipulation of generalized material balance and volumetric method for determination of oil in place are described in this paper. The oil water contact of an oil reservoir is mostly determined using well log data, for example carbon oxygen ratio and geophysical well logs.
