Patent number: 11966828Abstract: Permeability values are estimated based on well logs using regression algorithms, such as gradient boosting and random forest. The training data is selected from well logs for which core-analysis-based permeability values are available. The estimated permeability values are used to plan hydrocarbon production. The well logs used to build the depth blended model may include total porosity, gamma ray, volume of calcite, density, resistivity, and neutron logs. Selecting the training data may include grouping the well logs according to regions expected to have similar characteristics, choosing a subset of the well logs corresponding to wells expected to provide stable models according to pre-determined criteria, and/or identifying training zones on the chosen well logs according to one or more rules. Validation and consistency checks may also be performed.Type: GrantFiled: February 11, 2020Date of Patent: April 23, 2024Assignees: CGG SERVICES SAS, KUWAIT GULF OIL COMPANYInventors: Chiranjith Ranganathan, Francisco Brito, Ahmad S D S M Albussairi

Patent number: 4670104Abstract: A process and system is provided to produce and dedust oil from oil shale and other types of solid hydrocarbon-containing material. In the process, raw oil shale is retorted, preferably with solid heat carrier material, to liberate an effluent product stream of hydrocarbons containing entrained particulates of dust derived from the oil shale or other solid hydrocarbon-containing material. A fraction of oil containing most of the dust is separated from the effluent product stream and fed to one or more dedusters. The dust-laden oil is dissolved in a special mixture of dedusting solvents which contains both polar and non-polar dedusting solvents. In the deduster, the dissolved oil is separated into a dedusted stream of oil and solvents and a residual stream of dust-laden sludge. Solvents are recovered from the dedusted stream as well as the sludge. The recovered solvents are recycled to the deduster for use in dedusting the oil.Type: GrantFiled: June 28, 1985Date of Patent: June 2, 1987Assignees: Standard Oil Company (Indiana), Gulf Oil Corporation (Pennsylvania)Inventor: James L.

Patent number: 4552214Abstract: Greater product yield and quality and continuous upgrading of shale oil with hydrogen-rich, purge mode off gases is attained by pulsing in situ retorts at different phases and intervals. In the process, flow of feed gases to the flame fronts of underground retorts are sequentially stopped and purged while continuously retorting the oil shale to enhance transfer of sensible heat from the combustion zones to the retorting zones and enlarge the separation between the combustion zones and the advancing fronts of the retorting zones. The flame fronts can be purged with steam, water, carbon dioxide, nitrogen, hydrogen, combustion mode off gases, purge mode off gases, reactor off gases, or combinations thereof. The combustion mode off gases and/or purge mode off gases can also be used as part of the feed gas or fuel gas.Type: GrantFiled: March 22, 1984Date of Patent: November 12, 1985Assignees: Standard Oil Company (Indiana), Gulf Oil CorporationInventors: John M. Forgac, George R. Hoekstra

Patent number: 4548702Abstract: A process is provided to produce, stabilize, dedust and upgrade synthetic oil, such as shale oil. In the process, synthetic fuels, such as oil shale, tar sands and diatomite are retorted with heat carrier material to liberate an effluent product stream comprising hydrocarbons and entrained particulates of dust. In order to minimize polymerization of the product stream and agglomerate the dust, the product stream is stabilized, upgraded, and pretreated prior to dedusting, in a hydroprocessor, such as an ebullated bed reactor, with a hydroprocessing gas in the presence of a catalyst. The hydroprocessing gas can be hydrogen, scrubbed fractionator gases, or hydrocarbon-enriched hydroprocessor off gases.Type: GrantFiled: February 24, 1984Date of Patent: October 22, 1985Assignees: Standard Oil Company, Gulf Oil CorporationInventors: Earl D.

Patent number: 4529497Abstract: A process is provided for retorting synthetic fuels, such as oil shale, and disposing of the tailings in an environmentally acceptable manner. In the process, raw synthetic fuels are retorted in a surface retort to produce synthetic oil. The synthetic oil is dedusted and upgraded. The retorted synthetic fuels can be combusted and moisturized to generate heat for the retort, produce steam, and facilitate handling of the residual waste material (tailings). A disposal site of spent synthetic fuels, spent upgrading catalyst, dust, and/or other material is formed with vapor breaks at one or more levels in the pile. Air is passed through the vapor breaks to evaporate leachate rather than permitting the leachate to carry pollutants from the pile into the ground and surrounding bodies of water.Type: GrantFiled: March 26, 1984Date of Patent: July 16, 1985Assignees: Standard Oil Company (Indiana), Gulf Oil CorporationInventors: George H.

Patent number: 4495056Abstract: An oil shale process is provided to retort oil shale and purify oil shale retort water. In the process, raw oil shale is retorted in an in situ underground retort or in an above ground retort to liberate shale oil, light hydrocarbon gases and oil shale retort water. The retort water is separated from the shale oil and gases in a sump or in a fractionator or quench tower followed by an API oil/water separator. After the retort water is separated from the shale oil, the retort water is steam stripped, carbon adsorbed and biologically treated, preferably by granular carbon adsorbers followed by activated sludge treatment or by activated sludge containing powdered activated carbon. The retort water can be granularly filtered before being steam stripped. The purified retort water can be used in various other oil shale processes, such as dedusting, scrubbing, spent shale moisturing, backfilling, in situ feed gas injection and pulsed combustion.Type: GrantFiled: April 16, 1982Date of Patent: January 22, 1985Assignees: Standard Oil Company (Indiana), Gulf Oil CorporationInventors: Dean G.

Patent number: 4464993Abstract: An improved process is provided for blasting in situ oil shale retorts, and oil and gas wells. In the process, a specially formed concrete plug is installed at a desired depth in a bottomless blast hole and an explosive charge is placed upon the plug and detonated to blast the underground formation. The plug is accurately and reliably set by lowering a canister, which releasably houses a bag support assembly supporting a bag of concrete slurry, to a desired depth into the blast hole. The bag support assembly and bag of wet concrete are subsequently dropped a fixed distance below the canister. The bag of concrete expands, dries, and hardens against the walls of the blast hole to form a permanent stationary plug across the blast hole. In the preferred process, the bag support assembly is formed by casting a concrete disc around a drainpipe, and the bag support assembly is lowered and released from the canister with the aid of an electrically powered sequencer.Type: GrantFiled: June 30, 1982Date of Patent: August 14, 1984Assignees: Standard Oil Company (Indiana), Gulf Oil CorporationInventor: Darrell D.
