TL;DR: In this article, a plurality of wells are drilled to intersect the well bore and hot fluid is injected into the formation through these wells to cause viscous hydrocarbons to flow into the well-drone.
Abstract: In the practice of the present system, it is contemplated that the well bore will be of relatively large diameter such as in the range of about 1 to 10 ft. Also, the well bore should be drilled into the formation a sufficient distance to provide a sump in which the viscous hydrocarbons can accumulate. Thus, the well bore may be drilled completely through the subsurface formation. A plurality of wells are drilled to intersect the well bore and hot fluid is injected into the formation through these wells to cause viscous hydrocarbons to flow into the well bore. (10 claims)

TL;DR: In this paper, a premium synthetic lubricating oil base stock having a high VI and low pour point is made by hydroisomerizing a Fischer-Tropsch synthesized waxy, paraffinic feed wax and then dewaxing the hydro isomerate to form a 650-750° F.+ dewwaxate.
Abstract: A premium synthetic lubricating oil base stock having a high VI and low pour point is made by hydroisomerizing a Fischer-Tropsch synthesized waxy, paraffinic feed wax and then dewaxing the hydroisomerate to form a 650-750° F.+ dewaxate. The waxy feed has an initial boiling point in the range of about 650-750° F., from which it continuously boils up to at least 1050° F. and has a T90−T10 temperature difference of at least 350° F. The feed is preferably hydroisomerized without any pretreatment, other than optional fractionation. The 650-750° F.+ dewaxate is fractionated into two or more base stocks of different viscosity.

TL;DR: The fundamental quantum efficiency of the various processes that have been suggested, technological issues surrounding large-scale growth of hydrogen-producing microorganisms, and the scale and efficiency on which this would have to be practiced to make a significant contribution to current energy use are addressed.
Abstract: Photosynthetic microorganisms can produce hydrogen when illuminated, and there has been considerable interest in developing this to a commercially viable process. Its appealing aspects include the fact that the hydrogen would come from water, and that the process might be more energetically efficient than growing, harvesting, and processing crops. We review current knowledge about photobiological hydrogen production, and identify and discuss some of the areas where scientific and technical breakthroughs are essential for commercialization. First we describe the underlying biochemistry of the process, and identify some opportunities for improving photobiological hydrogen production at the molecular level. Then we address the fundamental quantum efficiency of the various processes that have been suggested, technological issues surrounding large-scale growth of hydrogen-producing microorganisms, and the scale and efficiency on which this would have to be practiced to make a significant contribution to current energy use.
