Abstract The voluminous amounts of hydrates found in nature are distributed across all continents and pose a huge possibility for future energy harvest. In fact, the total amount of energy stored in hydrates is predicted to be in the same range as conventional fossil fuels combined. Successful exploitation ...
The objective of this research is to determine the physicochemical processes underlying water and solute transport in organic-rich source rocks. Experiments were performed on Eagle Ford shale samples composed of organic-rich, low-clay carbonates using a high pressure triaxial assembly with novel design. ...
Maximizing the value of a significant gas resource base in southern Iraq for all key stakeholders is complex, driven by a number of key challenges on both the supply and demand-side of field development. The majority of the future gas supply in the south of Iraq will come from associated gas from some ...
Abstract This paper presents a systematic assessment of the potential of low salinity water flooding for the Dong-He-Tang reservoir in the Tarim Oilfield, China. This reservoir has a high reservoir temperature of 140 °C, high formation water salinity of 142,431 ppm total dissolved solids and an in-situ ...
Abstract Tight reservoirs normally have production problems due to very low matrix permeability and different damage mechanisms during drilling, completion and stimulation operations. These reservoirs have small pore throat size with significant capillary pressure energy suction that imbibes and holds ...
Abstract Seawater-based fracturing fluids are favorable in offshore locations because of the readily available seawater. This minimizes or even eliminates costly vessel trips that are necessary to transport fresh water to rig sites, while also reducing rig downtime. This paper presents the development ...
Abstract Iron sulfide scale is a common scale in sour oil and gas wells. It can form in wells producing oil and gas, as well as water injection wells. Iron sulfide scale has different forms based on the iron-to-sulfur ratio. Iron sulfide scale can form in soft forms that are removed easily by acids ...

Sound travels 4.5 times faster in water than in air and low frequency sounds (<100 Hz) can travel vast distances (>1000 km) with very little attenuation (NRC 2003). This transmission efficiency is likely why most marine animals, including whales and dolphins, are adapted to use sound the way terrestrial ...
Abstract This paper presents an overview of 50 years of development of fire and blast resistant walls for offshore installations and introduces the fourth generation or "Type" of wall. This thoroughly tested and certified 4th Type was developed as a response to the continuous quest to further optimise ...
Abstract Results from hundreds of studies, laboratory and basin experiments and field trials conducted worldwide over the past 50 years, in particular in the United States, Canada and Scandinavia, show that the industry has a wide range of viable technologies, beyond mechanical recovery, for oil spill ...
Abstract Ice accretion is a hazard for offshore operations on cold northern waters. Icing on vessel surfaces can be caused by a variety of phenomena, including cold air temperature, low water temperature, freezing rain, and supercooled fog, among others. A single salt water droplet's phase change behaviour ...
Abstract Fluid inclusions are micron scale samples of aqueous and hydrocarbon fluids trapped in annealed microfractures developed during burial, or earlier in authigenic minerals e.g. quartz and/or calcite during cementation. Microscopic studies are carried out on specially prepared doubly polished ...
Abstract As the demand for energy resources grew, the oil and gas industry looked north for exploration and development of offshore hydrocarbon resources. Significant discoveries were made in Arctic and sub-Arctic regions; however, these environments can be particularly unforgiving on pipelines and ...
Abstract The Rapid Access Ice Drill (RAID) was designed and built to rapidly drill through the Antarctic ice cap, and then core the ice-rock transition zone and underlying bedrock. The system is designed to be mobile and to operate autonomously near the South Pole at elevations of 3000 to 4000 m and ...
Abstract The aim of this paper is to describe an innovative composite structure called SoftHull developed for marine and amphibious vehicles capable of deforming without breaking under external actions. It is composed by a hull made of elastic and lightweight foam, supported by a rigid frame and protected ...
Abstract In order to address icing on ships, we develop sea spray meters, the sea spray particle counter (SPC) and the marine rain gauge type spray gauge (MRS), for measuring the spray particles and the amount of spray. The laboratory tests indicate that the amount of spray obtained by the MRS is close ...
Abstract It is increasingly important that decision makers for large capital projects (including development and decommissioning project phases) evaluate all project alternatives to determine the optimal final project configuration. The decision making process must take into account several important ...
Garbage decomposition that produces methane could be very dangerous if not detected properly. This study used methane gas sensor (MQ-4) to detect the presence of methane from the decomposition of fish guts waste. This study also compared different adsorbents such as charcoal, Sodium Bicarbonate and ...
This installment of Notes from the Community covers new drones and robots, ways to protect ourselves from bad drones, tracking mood disorders, opening up urban traffic planning to the public, and new methods to obtain a fish dinner.
