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 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 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 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 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 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 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 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 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 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 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 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 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 Many studies have been performed to identify chemical additives that will aid shale stability in large volume slick water fracturing treatments. Most of the targeted shale formations have a very low permeability, do not experience conventional leakoff and do not contain high amounts of swelling ...
Abstract: Factors confronting the application of surfactant flood in high temperature, high salinity carbonate reservoirs include: high concentration of divalent ions in the formation brine, the stability of the surfactant in high thermal environment, surfactant adsorption on carbonate rock fabrics ...
Abstract Reservoirs containing very high total dissolved solids and high hardness make the design of a surfactant polymer (SP) flood extremely difficult because surfactant tends to precipitate and separate under these conditions. Beside divalent ions, Ca2+, Mg2+, presence of iron in the brine can be ...
Abstract Chemical injection in enhanced oil recovery (EOR) projects is a complex process because it involves multiple chemicals with complex fluids. Costs for even a small-scale pilot test could be up in the millions of US dollars (USD) and large-scale field-wide expansion would be in the 100s of millions ...
Abstract This paper discusses a structured combination of procedures used to investigate polymers for EOR application with the focus on performance, compatibility with production chemicals and phase behaviour. This approach allows for early identification of risks and points to further work necessary ...
Abstract Low-salinity water flooding LoSal™ has been used to improve oil recovery for many decades. Historically, the physical mechanism behind this improvement in oil recovery was attributed to the pressure maintenance and displacement of oil by injected water. Recently, evidence from laboratory and ...
Abstract The deposition and accumulation of inorganic scales is a major concern for oil and gas producing companies worldwide. This concern typically stems from two main factors: the strong possibility of total production loss due to scale plugging of production conduits, and the significant impact ...
