Abstract: A method is described for identifying source rocks in a subsurface volume of interest. The method may include generating a trend-normalized reflectivity seismic attribute and calculating the location, thickness, organic richness and thermal maturity of the potential source rocks based on seismic data. The method may be executed by a computer system.

Abstract: The disclosure is related to methods of drilling two wells, wherein the two wells are drilled such that the toe of the lateral portion of one well is in proximity to the heel of the lateral portion of the other well. Production from the wells can be improved by a process wherein the formation about the wells is first fractured at the toe of each lateral portion, then fractured along the middle section of each lateral portion, and, lastly, at the heel section of each lateral portion of the wells.

Abstract: Embodiments of categorizing fractures in a subsurface formation are provided herein. One embodiment comprises obtaining at least one borehole image for a plurality of fractures in a subsurface formation and at least one resistivity log for the plurality of fractures of the surface formation. The embodiment comprises determining first aperture data based on the at least one borehole image for the plurality of fractures and determining second aperture data based on the at the least one resistivity log for the plurality of fractures. The embodiment comprises comparing the first aperture data based on the at least one borehole image and the second aperture data based on at least one resistivity log to determine whether to categorize each fracture of the plurality of fractures as a naturally occurring fracture or a non-naturally occurring fracture. The embodiment comprises generating an output indicating the categorization of each fracture and displaying the output.

Abstract: A subsurface representation may define simulated subsurface configuration of a simulated subsurface region. The simulated subsurface region may include simulated wells, and the simulated subsurface configuration may define simulated correlation between the simulated wells. Subsurface configuration of wells may be compared with the simulated subsurface configuration to generate similarity maps for the wells. The similarity maps may be arranged based on spatial arrangements of the wells such that the similarity maps overlap with each other within an overlap area. Locations within the overlap area may correspond to groupings of matched simulated wells. Correlation between the wells may be determined based on the simulated correlation between the matched simulated wells.

Abstract: A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-116, is provided. SSZ-116 can be synthesized using 3-[(3,5-di-tert-butylphenyl)methyl]-1,2-dimethyl-1H-imidazolium cations as a structure directing agent. SSZ-116 may be used in organic compound conversion reactions and/or sorptive processes.

Abstract: Described herein are various embodiments of computer-implemented methods, computing systems, and program products for analyzing a flood operation on a hydrocarbon reservoir. For example, an embodiment of a computer implemented method of analyzing at least a first flood operation and a second flood operation. The embodiment includes, for each flood operation: receiving production data and injection data, running capacitance resistance modeling, using the generated response times, the generated interwell connectivities, the received production data, the received injection data, or any combination thereof to generate a proxy of pore volume swept per well pair, and aggregating the generated proxies to generate an estimate of pore volume swept at a well level, at a reservoir level, or both for the flood operation. The embodiment also includes comparing the generated estimate of pore volume swept to determine a change in sweep efficiency at the well level, at the reservoir level, or both.

Abstract: Provided is a continuous process for converting waste plastic into recycle for polypropylene polymerization. The process comprises selecting waste plastics containing polyethylene and/or polypropylene, and passing the waste plastics through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a naphtha/diesel fraction, a heavy fraction, and char. Pyrolysis oil and wax, comprising naphtha/diesel and heavy fractions, is passed to a refinery FCC unit. A liquid petroleum gas C3 olefin/paraffin mixture is recovered from the FCC unit. The C3 paraffins and C3 olefins are separated into different fractions with the C3 olefin fraction passed to a propylene polymerization reactor, and the C3 paraffin fraction passed optionally to a dehydrogenation unit to produce additional propylene.

Abstract: Provided is a continuous process for converting waste plastic into recycle for polyethylene polymerization. In one embodiment, the process comprises selecting waste plastics containing polyethylene and/or polypropylene and passing the waste plastics through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a naphtha/diesel fraction, a heavy fraction, and char. The naphtha/diesel fraction is passed to a crude unit distillation column in a refinery where a straight run naphtha (C5-C8) fraction or a propane/butane (C3-C4) fraction is recovered. The straight run naphtha fraction (C5-C8) or the propane/butane (C3-C4) fraction is passed to a steam cracker for ethylene production. The heavy fraction from the pyrolysis unit can also be passed to an isomerization dewaxing unit to produce a base oil.

Abstract: Provided is a continuous process for converting waste plastic into recycle for polyethylene polymerization or for normal alpha olefins. The process comprises selecting waste plastics containing polyethylene and/or polypropylene and then passing the waste plastics through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a naphtha/diesel fraction, a heavy fraction, and char. The naphtha/diesel fraction is passed to a crude unit in a refinery from which is recovered a straight run naphtha fraction (C5-C8) or a propane/butane (C3-C4) fraction. The straight run naphtha fraction, or propane and butane (C3-C4) fraction, is passed to a steam cracker for ethylene production. The ethylene is converted to normal alpha olefin and/or polyethylene. Also, a heavy fraction from the pyrolysis reactor can be combined with a heavy fraction of normal alpha olefin stream recovered from the steam cracker. The combined heavy fraction and heavy fraction of normal alpha olefin stream can be passed to a wax hydrogenation zone to produce wax.
