Restriction of gas losses in an overpressurised CO 2 reservoir using gel technology
The overpressurised CO 2 field Bečej (Serbia) was explored in 1951. At the end of 1968, an uncontrolled gas blowout of Bč-5 well lasted 209 days resulting in 35 bars pressure drop in the reservoir until 2007. Hence, the substantial loss of reserve (> 17 billion m 3 ) became a critical issue of the operator. Environmental friendly chemicals should be used only for well rehabilitation. ...

Exergy of natural gas flow in Iran's natural gas fields
Natural gas flow has a valuable pressure exergy which is currently destroyed in throttling valves at exit of the gas fields. In the current study, this pressure exergy has been calculated for an actual case. Exergy analysis was based on actual condition of the Shanol gas field, which is situated in Iran, in the summer. It is assumed to be a good representative of Iran's whole gas fields. Exergy ...

Evaluation research on performance of permeability and fracture in Sulige gas field by new method
Tight gas is the most available alternative unconventional natural gas in China. Its potential is huge and the Sulige gas field is the biggest one. However, there are many urgent development problems to be solved, and evaluating well performance is of one of them. Low permeability, strong stress sensitivity and hydraulic fracturing make it difficult to predict well performance. Evaluating the ...

Behavior of Flame Spread Downward over Thick Wood Sheets and Heat Transfer Analysis
To investigate the flame spreading mechanism over charring materials under natural convection, wood sheets from 0.9 to 3 mm thickness have been chosen. The variation of mean flame spread velocity V with thickness is measured. Typical flame shapes over the wood surfaces are recorded using CCD. The temperature fields in the gas phase are examined by a set of fine thermocouples. On the basis of the ...

Verification of Wind-Driven Volatilization Models
Abstract Mass-transfer processes of paramount importance, such as reaeration and volatilization, occur at the air–water interface. Particularly, volatilization is intensively studied because it can be a relevant removal process for toxic contaminants from flowing and standing surface waters. The paper provides a comparison among predictive equations available from literature for standing waters ...

LNG For Exploration & Production - Drilling Operations - Case Study
Use of gas in drilling actually began several years before (2010) use of gas in frac operations (2013). The scope of a rig retrofit with three (3) engines vs. 12-20 engines on a frac spread is one major reason why drilling innovated with natural gas before frac operations. At one time (mid-2014) there were over 100 drilling rigs employing natural gas either in a dual fuel configuration with ...

Hydrate risks and prevention solutions for a high pressure gas field offshore in South China Sea
YC13-4 gas field is located in the west of the South China Sea, where the seawater depth is around 90 m, and the average surface temperature is 26.2°C, while the minimum temperature at seabed is 18.9°C. Subsea wellheads are designed for gas production. In this paper, the risks of hydrate formation during drilling, well testing and gas production are analysed under different operation conditions. ...

Gas flow control method of recycling gas drilling technology
Recycling gas drilling is a new drilling technology. The paper based on the theory of gas transient flow, a set of theoretic models of gas flow control at the export of annulus are set up in combinations of the principles of the seepage flow mechanics and the characteristics of recycling gas drilling technique. According to the basic laws which the flowing gas should comply with, the properties ...

The Gorgon project: legal and policy issues
IntroductionOn 14 September 2009, Australia’s largest commercial carbon capture and storage (CCS) project, the Gorgon Joint Venture (GJV), was approved by the Western Australian Government. While the GJV is being undertaken in a legal and regulatory framework which is project specific rather than part of a fully integrated domestic legal framework, Gorgon itself is an integrated CCS project and ...

BP/BTC Pipeline Project
The Baku-Tbilisi-Ceyhan pipeline is a 1,768 kilometres (1,099 mi) long crude oil pipeline from the Azeri-Chirag-Guneshli oil field in the Caspian Sea to the Mediterranean Sea. It connects Baku, the capital of Azerbaijan; Tbilisi, the capital of Georgia; and Ceyhan, a port on the south-eastern Mediterranean coast of Turkey, hence its name. It is the second longest oil pipeline in the world after ...

Quick laboratory analysis of gas condensate in produced water
Abstract Often there is a need for quick field measurement of gas condensate concentration in produced water, such as when performing process optimization, water treatment verification and routine process monitoring. Rigorous laboratory analysis methods such as gravimetric oil and grease measurements or gas chromatographic methods are not sufficiently sensitive to process changes and/or do not ...

Comparison of greenhouse gas analyzers -measurements using photoacoustic, laser, FTIR analyzers and gas chromatography
In the last decades, several technologies have been developed to measure greenhouse gas (GHG) concentrations and fluxes. We compared six devices using different measurement technologies: two gas chromatographic systems with a barrier discharge ionization detector (GC-BID) and an electron capture detector (GC-ECD), respectively, a portable GHG analyzer based on laser absorption, a photoacoustic ...
