Abstract Viscoelastic surfactants can provide viscoelastic properties in brines at high temperatures (higher than 230°F). Recent studies have shown the advantages of use nanoparticles in VES fluid systems. The nanoparticles have large surface area as well as unique surface morphology and surface reactivity. ...
Abstract Slickwater hydraulic fracturing is commonly used to stimulate unconventional formations, including many shale reservoirs. Large volumes of water and additives are pumped downhole at high rates to propagate the fractures and delay proppant settling. At high flow velocities, proppants in friction ...
Abstract When operating in areas of Africa which are particularly sensitive environmentally selection of drilling fluids should take into account both technical and environmental criteria in regards to the treatment and disposal of the cuttings and excess fluids. In this particular case the operator's ...
Abstract In June 2010, as part of an operation in a producing well, offshore eastern Canada, a junk basket on wireline tagged its depth and became stuck. The bottomhole assembly (BHA) was disconnected and left in the well. When the wireline was back at surface, scale was determined to be the reason ...
Abstract BP's largest subsea development, PSVM, sits in water depths of 2,000 metres located north-west of Luanda in block 31. It's the first ultra-deepwater development in the continent of Africa and the most expansive sub-sea development in the industry to date due to the combination of water depth ...
Abstract Social Licence to Operate - non-technical risk in new field development. The term Social Licence to Operate describes broad public acceptance of a proposed development and winning this licence and maintaining it, requires that the Non-Technical Risks (NTR) associated with a project ...
Abstract The development of gas transportation projects is considered as one of the main causes of the loss of biodiversity, habitat fragmentation and edge effect. This study has important implications in terms of conservation, forest regeneration and wildlife management.The biological monitoring methodology ...
Abstract Many Oil and Gas Exploration and Production (O&G) companies devote significant resources to keep their employees safe, protect the environment around their operations, stimulate local economies and build strong and trusting relationships with community stakeholders. Despite these efforts, ...
Abstract The understanding of single and multiphase flow behavior in porous media has been improved with the development of in situ saturation measurement techniques such as X-ray Computed Tomography (CT), mainly in specialized core analysis. On the other hand, effective experimental designs are necessary ...
Abstract Polymeric scale inhibitors are widely used in the oil and gas field because of their better thermal stability and improved environmental compatibility. However, the squeeze performance of such inhibitors is typically poorer than that of the phosphonates type scale inhibitors in conventional ...
Abstract Until around 1990 the main marine geohazard risk addressed solely from geophysical data was the presence of shallow gas. Presence had been described using a number of non-standard approaches for its potential presence - distinct from the actual risk it presented to operations. In the 1992 UKOOA ...
Abstract Using photons to sense instead of electrons has many advantages, which is why photonic sensing is slowly maturing from a niche into a fully-fledged mature technology. In the O&G business, photonic sensing has gained ground and in some cases is even becoming the standard. Most of these systems ...
Abstract With the advent of increased production of Shale Gas in United States, and the continuing drop in gas prices, the possibility of exporting US gas is becoming more real. Many developers are vying to build larger capacity LNG production facilities for exporting to Free Trade Agreement (FTA) and ...
Abstract Recent discoveries offshore Brazil have induced a renewal of interest in the study of recent and ancient continental carbonate systems which developed in a wide range of depositional settings, reflecting aerial to subaqueous environments. Recent and ancient continental carbonate analogs provide ...
Abstract Pilot-CO2 flooding in Jilin Oil Field has been got a first base in recent years in order to ensure CO2 coming from the development of volcanic gas reserves is available for utilizing. The project has come into extended testing stage and will get into a Carbon Industry Chain(CIC) production ...
Abstract Inhibitor squeeze treatments have been regularly carried out to prevent both sulphate and carbonate scale depositions from reservoir to topside facilities in North Sea field since 1990s. Some of the wells, especially for the short perforation, high water production wells and relatively clean ...
Abstract It is well known that with continued production from wet gas reservoirs, the reservoir pressure eventually falls below the dew point pressure leading to condensation and loss of gas productivity in the reservoir. The concept of simultaneously injecting CO2 in a gas reservoir for long term ...
Introduction Regulatory agencies use environmental assessments as the best available indicators of information on national conditions and trends in air, water, land, human health, and ecological systems. The results from these assessments are used in legislative discussions and proceedings to promulgate ...

As the typical agricultural ecological section, the constructed wetland of rice paddy field is one of the most important environmental assets of human being, it's closely interrelated to our life and social development. However, with the development of economic, a large area of irrational exploitation ...
