Abstract: Methods and systems for measuring neutron sigma of downhole reservoir as a function of time for a predetermined testing volume are disclosed. The methods and systems of the present invention analyze the testing volume while maintaining the formation in the testing volume in an unchanged and undamaged state and while dynamically flowing fluids in and out of the testing volume. The systems and methods of the present invention are especially important in determining petrophysical information about the reservoir as well as the in-situ effect of substances on enhanced oil recovery.

Abstract: Methods and systems for collecting high quality reservoir samples and determining producibility of those samples are disclosed that provide for a non-stop and no shock sampling process. The systems and methods of the present disclosure are especially important collecting samples of reservoir samples in a manner that most closely resembles production fluids and maintains the reservoir at or near the draw down pressure during the pumping and sampling processes.

Abstract: A drive system includes a current sensor configured to generate a first current signal representative of a current flowing in one or more electrical devices electrically coupled together through a power supply bus, a power output bus, and a common ground. The drive system also includes a voltage sensor configured to generate a first voltage signal representative of a voltage with respect to the common ground in the one or more electrical devices. The drive system further includes a ground fault detection controller configured to determine a ground fault in the one or more electrical devices based on a change in at least one of the first current signal and the first voltage signal.

Abstract: A safe and effective method for remediation and removal of trapped oil, since oil spills trapped under ice present a significant environmental problem. Injector wells are placed around a periphery of trapped oil to inject fluids beneath the ice. A producer well is placed within the periphery and the hydrostatic pressure from the injector wells urges the oil toward and up through the producer well.

Abstract: Oil spills trapped under ice present a significant environmental problem. Disclosed is a method that provides a safe and effective method for remediation and removal of such trapped oil. The method provides for injector wells to be placed around the periphery of trapped ice to inject fluids beneath the ice. A producer well is placed within the periphery and the hydrostatic pressure from the injector wells urges the oil toward and up through the producer well.

Abstract: A system and method for acquiring domain visitor on a parking service and redirecting the visitor to two or more optimal advertisers is disclosed. The system comprises a processor, and a partner module comprising a first set of software instructions executing on the processor, wherein said first set of instructions are configured to determine a computed bid to acquire a domain visitor for a domain at a rate of profitability. The first set of instructions are further configured to break down the domain into a keyword cloud, and to select at least one of said advertisers based on the computed bid and the keyword cloud. The first set of instructions are further configured to redirect the visitor to a uniform resource locator for the selected advertiser.

Abstract: An apparatus and methods for acoustically analyzing a fluid sample and determining one or more properties of the sample are disclosed by the present invention. The apparatus comprises a chamber, a transmitter positioned within the chamber for transmitting an acoustic signal through the fluid, a reflector movably positioned within the fluid inside the chamber for reflecting the acoustic signal, and a receiver positioned within the chamber for detecting reflections of the acoustic signal. The methods employ the use of a transmitter, a reflector movably positioned within the fluid inside the chamber, and a receiver to characterize the fluid sample based on one or more of its acoustic properties.

Abstract: A system and method are disclosed for efficient and reliable deployment of radioactive markers and remote sensors in earth formations through cased wellbores. The markers and sensors are permanently deployed to obtain data on compaction, pressure and other useful formation properties.

Abstract: A novel, salt-free monoamphopropionate amphoteric surfactant is prepared in yields of from 75% to 80%, from a reaction comprising an imidazoline and a mixture of acrylic acid and sodium acrylate in an aqueous medium. The acrylic acid/sodium acrylate mixture is comprised of the two components in a range of molar ratios of from about 1:6 to about 1:3, respectively, and by replacing methyl acrylate, the reaction does away with the production of methanol which is an unwanted, hazardous and toxic byproduct. The imidazoline reacts in amounts in excess of 90% resulting in the highly pure yields and any left over unreacted acrylic acid can be easily removed by treating it with sodium bisulfate.
