Unlike other problems found in the oil industry, the allocation of compressors to gas-lifted oil wells lacks formal models and algorithms capable of delivering globally optimal assignments. To this end, this paper casts the compressor allocation problem as a facility location problem. Owing to the special structure of the target problem, an efficient (polynomial time) algorithm is conceived by ...

this research studies the application of hybrid algorithms for predicting the prices of crude oil. brent crude oil price data and hybrid intelligent algorithm (time delay neural network, probabilistic neural network, and fuzzy logic) were used to build intelligent decision support systems for predicting crude oil prices. the proposed model was able to predict future crude oil prices from august...

Abstract Volume transformation technology has become a key for developing low-permeability/tight oil and gas reservoirs. Evaluating the post-fracturing effect is very important development plan formulation fracturing evaluation. In this paper, vicinity of main fracture divided into zone secondary zone. The with infinite conductivity branch increased permeability are used to describe area. Based...

The Periodic Mobile Piston Pump Unit Routing Problem consists of, given a set of surface oil wells scattered over an onshore producing field, determining routes for each day of work, with limited duration work shift, that maximize the collection of oil carried by a mobile piston pump unit. This paper presents different construction and local search methods used in the composition of GRASP and I...

The problem of suppressing the slugging phenomenon is investigated. Industrial oil facilities such as gas-lifted wells and offshore production oil-risers are examples of systems where occurs such phenomenon. To study this problem, we consider that these systems are written as a set of 3 × 3 hyperbolic partial differential equations of balance laws, where the control variable appears at the boun...

Despite widespread acceptance and application of real options theory in the economic literature, little empirical work has attempted to assess the extent to which firm behavior accords with the theory’s prescriptions. In particular, it is not well-known whether, or by how much, firms actually delay irreversible investments following an increase in the uncertainty of their economic environment. ...

We are concerned with robust and accurate forecasting of multiphase flow rates in wells and pipelines during oil and gas production. In practice, the possibility to physically measure the rates is often limited; besides, it is desirable to estimate future values of multiphase rates based on the previous behavior of the system. In this work, we demonstrate that a Long Short-Term Memory (LSTM) re...

-This paper based on crossplot and core data,analysis the Pu Xi oilfield ,Putao Hua oil layer ‘s conventional logging response characteristic.Based on the describe of the three cored wells, Putao Hua oil layer is mainly made up with siltstone, muddy siltstone, silty mudstone,. First normalized the well logging curves, elimination the influence of the nongeological factors to the well logging cu...

94 Production from heavy-oil fields in the UK continental shelf (UKCS) has become possible over the past 10 years. Despite substantial reserves in the UKCS of crudes with gravitiy of 20°API and lower, most of the activity has been exploration and appraisal drilling. The main reason for restricted activity has been high uncertainty of reservoir and fluid properties. A method was developed to fin...
