10 Oct 2007TL;DR: In this paper, a method for spacing heater wells for an in situ conversion process is provided, which includes the steps of determining a direction along which thermal energy will travel most efficiently through a subsurface formation, and completing a plurality of heater wells.
Abstract: A method for spacing heater wells for an in situ conversion process is provided The method includes the steps of determining a direction along which thermal energy will travel most efficiently through a subsurface formation, and completing a plurality of heater wells in the subsurface formation, with the heater wells being spaced farther apart in the determined direction than in a direction transverse to the determined direction In one aspect, the step of determining a direction along which thermal energy will travel most efficiently is performed based upon a review of geological data pertaining to the subsurface formation The geological data may comprise the direction of least horizontal pnncipal stress in the subsurface formation Alternatively, the geological data may comprise the direction of bedding in the subsurface formation, the tilt of the subsurface formation relative to the surface topography, the organic carbon content of the kerogen, the initial formation permeability

TL;DR: In this paper, the interaction between hydrophobically modified polymers (hm-polymers) and surfactants was investigated by steady-state fluorescence as well as rheological experiments.
Abstract: Interactions between hydrophobically modified polymers (hm-polymers) and surfactants were investigated by steady-state fluorescence as well as rheological experiments. Hydrophobically modified hydroxyethylcellulose (hmHEC) with C16 hydrophobe grafts of 0.9% mole along with tetradecyltrimethylammonium bromide and cetyltrimethylammonium bromide were studied. The presence of C16HEC induced the aggregation of surfactant micelles in aqueous solution at concentrations about one-half times lower than the critical micelle concentration. As surfactant is added, the viscosity of hm-polymer solution first increases due to the bridging of hydrophobe clusters by surfactant micelles to form mixed micelles and later decreases due to the masking of hydrophobes individually by excess micelles. Fluorescence quenching experiments showed that the number of hydrophobes (NH) in a mixed micelle decreases steadily with increasing surfactant concentration due to hydrophobe dilution by the surfactant. NH declines from greater than...

26 Jan 2001TL;DR: In this paper, formulated lubricant oils derived from a highly paraffinic basestock are described. But the formulation of the oils is restricted to a single paraffin base stock.
Abstract: The present invention relates to formulated lubricant oils derived from a highly paraffinic basestock. The formulated lubricant oils of the present invention comprise a wax isomerate paraffinic hydrocarbon basestock component in which the extent of branching, as measured by the percentage of methyl hydrogens (BI), and the proximity of branching, as measured by the percentage of recurring methylene carbons which are four or more carbons removed from an end group or branch (CH2 > 4), are such that: (a) BI - 0.5(CH2 > 4)15; and (b) BI + 0.85(CH2 <<45; as measured over the hydrocarbon basestock as a whole. Preferably, the wax isomerate basestocks to be used in the lubricating oils of the present invention have a biodegradability value of at least 50 % under OECD 301 B test. In addition, these basestock components have pour points of about -25 °C or lower. They are also characterized by unexpectedly good low-temperature and high-temperature viscosities, with CCS viscosity at -15 °C of not more than about 3 500 cP, and with a kinematic viscosity at 100 °C of about 5 cSt or greater. Desirable multigraded oils obtained using these basestocks may include 0W-, 5W-, 10W-, and 15W-XX grades (XX=20-60).
