MODULARIZATION, INNOVATION AND COMPLIANCE
… There is a need for each machine unit working in oilfields has its own data storage to store specification documents associated with it so that an operator can easily refer to during operation. A possible solution to this has been come up with, in which a commercialized innovative USB device has …

Monitoring of oil-production-induced subsidence and uplift
… based on the example of the data from one of the oilfields in the western part of Kazakhstan. The geodetic techniques used for this project include interferometric synthetic aperture radar (InSAR), continuous and campaign global positioning system (GPS) surveying, precise leveling surveying, and …

Exploring the value proposition of integrating back-up saline storage into anthropogenic CO₂ supplied EOR operations
… system utilizes brine formations adjacent to EOR oilfields for the purpose of storing any additional quantities of CO₂ the EOR operation cannot handle. The concept of a stacked storage system with focus on CO₂ supplies from coal-fired power plants was analyzed using a case study. A U.S. coal-fired …

The Damage Done
… home, the oil wells from the East Poplar oilfields can be seen in the distance. Her water started to change in the early 1970’s, twenty years after the first oil well was drilled. It took about that long for the contamination from poorly regulated drilling practices and leaking wells to …

The Norwegian state's relationship to the international oil companies over North Sea oil, 1965-75
… changes in the expected Present Value from the oilfields in the North Sea; secondly the situation in the international oil industry; and thirdly the special characteristics of the Norwegian state. While development of the first two factors opened up the way for a strengthening of the role of the …

Digital Rock: Understanding the mechanism of Enhanced Oil Recovery (EOR) Core Floods
… extending the productive life of their existing oilfields. For that purpose, a better understanding of the physical phenomena which occur during waterflooding and enhanced oil recovery (EOR) is needed to optimise the oil recovery. In this thesis, Nuclear Magnetic Resonance (NMR) has been employed …

Geomechanical impact of bio-competitive exclusion chemical on reservoir rocks.
This study describes a novel approach known as "bio-competitive exclusion", which uses chemical nitrates as an oilfield chemical to treat reservoir souring and control the activities of sulfate-reducing bacteria. Because of its flexibility and extensive use in oil production, this oilfield …

Exports of Iranian natural gas to regional and international markets: a study of political, legal and economic barriers
… as country’s dependence on gas re-injection into oilfields to maintain the oil production, Iran may not want to be “the next Qatar” in terms of exports. Available data suggest that gas export is not the most beneficial economic outcome for Iranian gas; and for all of the foregoing reasons, and …
