This article discusses t,he selection of the domain for a knowledge-based expert system for a corporate application The selection of the domain is a critical task in an expert system development At the st,art of a project looking into the development of an expert, syst,em, the knowledge engineering project team must investigate one or several possible expert system domains They must decide whet...

Auto regressive integrated moving average (ARIMA) models have been widely used to calculate monthly time series data formed by interannual variations of monthly data or inter-monthly variation. However, the influence brought about by inter-monthly variations within each year is often ignored. An improved ARIMA model is developed in this study accounting for both the interannual and inter-monthl...

The article reveals the environmental aspects of competitiveness strategies mining enterprises in context ensuring sustainable development economy. reasons as a result which state environment process oil and gas fields worsens are investigated. stages search for exploration considered. negative impact on component prospecting exploitation works has been determined.

China’s economy is in an important period of rapid development, the rise various industries to produce a greater demand for oil, oil exploitation industry has become focus whole society. The vast majority fields China have entered polymer flooding development stage, and reservoir been effectively improved. subsequent water can make further excavated, which key technology recent years. This pape...

In the process of rapid social and economic development, demand for oil related industries is more large. The continuous increase exploitation causing some fields to gradually enter period special high water cut development increasing difficulty exploitation. Therefore, how improve recovery key question that relevant personnel think solve. Based on this, this paper mainly describes channel sand...

Maintaining good conditions for petroleum exploitation is an important basis achieving better results. At present, the main reservoir of our oil fields are relatively good, and have entered high water cut, middle late development. Due to long-term exploitation, has suffered a certain degree destruction, resulting in rapid rise aquifers sharp reduction production. It influence on output well fin...

Oil and gas exploration in the South China Sea (SCS) has garnered global attention recently; however, uncertainty regarding the accurate number of offshore platforms in the SCS, let alone their detailed spatial distribution and dynamic change, may lead to significant misjudgment of the true status of offshore hydrocarbon production in the region. Using both fresh and archived space-borne images...

Petrochemical industry is one of the key industry areas where Internet of Things (IoTs) and big data analytics could be widely applied to support smarter production and maintenance. In oil and gas exploitation, sucker-rod pumping systems are used in approximately 90 percent of artificially lifted wells. An automatic pipeline is crucial for real-time condition monitoring and fault detection of t...

The hue and cry about the stark despoliation of the Niger Delta has been ongoing; and the issues at stake have centered mostly on the gross and glaring underdevelopment in the area despite the vast resources that have accrued to the Nigerian state from the region. Perhaps the most disturbing, is that oil exploration and exploitation in the Niger Delta is carried out without regard to internatio...
