Oil-based drilling fluid is used more and more in the field of oil and gas exploration. However, because of unrecyclable treating agent and hard treatment conditions, the traditional treating technologies of waste oil-based drilling fluid have some defects, such as waste of resource, bulky equipment, complex treatment processes, and low oil recovery rate. In this work, switchable deoiling agent...

This paper introduces an effective production optimization and a water injection allocation method for oil reservoirs with water injection. In this method, a two-stage adaptive simulated annealing (ASA) is used. A coarse-grid model is made based on average horizon permeability at the beginning iterations of the optimization to search quickly. In the second stage, the fine-grid model is used to ...

The following paper explores the development of a statistically based index evaluating digitalization processes to assess digital divide between regions Kazakhstan: resource-based (oil and gas) where service sector dominates GRP. As method for forming such an indicator, authors suggest using factor analysis, which reduces dimension factors while maintaining reasoning behind significant part dat...

In this study the energy and economic flows and greenhouse gas (GHG) emissions of olive oil production in Iran were investigated in terms of a life cycle assessment with considering four main stages of agricultural olive production, olive transportation, olive oil extraction and its oil transportation to the customer centers. Data was collected from 150 olive growers in Guilan province of Iran....

in this research, both resource allocation and reactive resource allocation problems in multi-server dynamic pert networks are analytically modeled, where new projects are expected to arrive according to a poisson process, and activity durations are also known as independent random variables with exponential distributions. such system is represented as a queuing network, where multi servers at ...

introduction: family physician plan in iran was conducted to establish service referral system. its urban step began in 2012 and it was supposed that the effectiveness is enhanced and the costs are reduced. the implementation of this program has faced some challenges, especially in human resources management. the aim of this study was to optimally allocate human resources for urban family physi...
