AIM Heavy silicone oil removal can be challenging and differs considerably from conventional oil. Traditionally, strong active aspiration had to be applied through a long 18G needle just above the optic disc. We present a novel technique using a much shorter (7.5 mm) and smaller (20G) needle allowing its removal "from a distance." METHOD Active aspiration on a vacuum of 600 mm Hg of the "visc...

Objective: To characterize the fluid properties and fluid-rock interactions that are needed for formation evaluation by NMR well logging. This project is a partnership between Professor George J. Hirasaki at Rice University and Professor Kishore Mohanty at University of Houston. In addition to the DOE, a consortium of oil companies and service companies supports this project. The advances made ...

A fluidized bed reactor that is operating in the bubbling regime has been developed for the conversion of bio-oils to syngas.The reactor consists of a 7.6 cm I.D. (or internal diameter) bed, with an expanded freeboard. The volume of the reactor can be adjusted to vary the gas residence time. This reactor has been used to carry out either thermal or catalytic cracking for reforming bio-oils.A ga...

This work experimentally validates the feasibility of a tactile exploration approach to map harsh environments such as deep sea oil well sites. The recent collapse of the offshore oil-­drilling platform Deepwater Horizon in the Gulf of Mexico resulted in the largest marine accidental disaster in history. Initial attempts to control the spill failed be-­ cause of the very challenging environment...

HEAVY silicone oils have shown promising results in the treatment of retinal detachments in the inferior quadrant in several studies. However, their use remains controversial, attendees at a symposium at the 7th EURETINA Congress heard. Proponents of silicone oil say that the specific gravity of these compounds makes them more efficient than conventional silicone oils in providing inferior tamp...

Canadian oil sands are unconsolidated sand deposits that are impregnated with heavy, viscous petroleum, normally referred to as bitumen. The total bitumen in place in Alberta is estimated at 1.7 to 2.5 trillion barrels and is clearly massive by world standards. Presently, 25% of the Canadian energy needs are derived from upgraded bitumen from mined oil sands. The oil sands are a complex mixture...

Recycle-gas injection is a promising recovery process to produce oil and gas. The method uses continues injection of the produced gas at economical rates to keep the reservoirs energy up and using viscous force as the driving force. There are numerous studies done on recycle-gas injection in conventional reservoirs, however, there are some other factors such as location of wells and completion ...

This paper describes the experimental study of the shaft oil feed mechanism of a rotary compressor. The oil contained in the shaft in which an oil pump is inserted is fed to the respective sliding surfaces of the subbearing section, eccentric section and main bearing section of the shaft by centrifugal force of shaft rotation. The oil feed pressure of shaft rotation is approximately 0.1 kg/cm2 ...
