This paper proposes an optimization strategy which is based on neural networks and genetic algorithms to calculate the optimal values of gas injection rate and oil rate for oil production system. Two cases are analyzed: a) A single well production system and b) A production system composed by two gaslifted wells. For both cases an objective function is maximized to reduce production cost. The p...

Inflow control devices (ICD), which prevent water breakthrough by controlling the inflow profile of a well, have been used successfully in many oilfields. This paper will introduce a new discovery and an unsuccessful example. Moreover, this paper investigates meticulously and thoroughly to find the application conditions of the new discovery. Based on permeability rush coefficient and permeabil...

Most traditional injection-production optimization methods that treat the entire oil reservoir as a whole require re-optimization when facing new reservoirs, which is not only time-consuming but also does make full use of historical experience information. This study decomposes into independent basic production units to increase sample size and diversity utilizes image enhancement techniques au...

BACKGROUND The leaves of Ocimum basilicum L. (basil) are used in traditional cuisine as spices; its essential oil has found a wide application in perfumery, dental products as well as antifungal agents. AIM To assess the chemical composition as well as the in vitro antifungal activity of O. basilicum L. essential oil against Aspergillus flavus fungal growth and aflatoxin B1 production. MATE...

The article proposes a methodology for the development of flexible management decisions based on technical and economic assessment efficiency operation each production well. This method managing costs makes it possible to avoid occurrence cash gaps during period low prices hydrocarbon resources facilitate implementation both investment programs company.

The recently developed smart well technology allows for sectionalized production control by means of downhole inflow control valves and monitoring devices. We consider borehole radars as permanently installed downhole sensors to monitor fluid evolution in reservoirs, and it provides the possibility to support a proactive control for smart well production. To investigate the potential of borehol...

The rapid increase of palm oil (PO) production in the last 20 years has made it the most important oil in the world. By year 2007, the annual global production of PO reached 40 million metric tons. Currently, Malaysia accounts for almost 50% of world palm oil production. As most of natural oils, PO has only a limited application in their original form, as a consequence of its complex chemical c...
