Abstract: This disclosure relates to systems and methods associated with a replenishable receptacle for tagger and/or tracer material in a wellbore. The system may include a receptacle configured to contain tracer material and release tracer material into fluid flowing in a wellbore responsive to the fluid flowing adjacent to the receptacle, The tracer material includes a distinctive element or chemical configured to facilitate determining information associated with movement of fluid in the wellbore. A rate of the release of the tracer material may be related to a rate of flow of the fluid in the wellbore. The receptacle may be further configured to be refilled with tracer material responsive to the tracer material contained by the receptacle being depleted. Refilling the receptacle may be performed via one or more of a wireline, a coiled tubing, a tractor, a robot, a work-string and/or tubing from a light intervention vessel, and/or other approaches.

Abstract: A system for combusting boil-off gas and generating electricity at an offshore LNG marine terminal distant from an onshore LNG facility is disclosed. BOG produced as a result of LNG transfer between an onshore LNG facility and an LNG carrier, is combusted to produce power which drives an electrical generator producing electricity. None or a reduced amount of BOG needs to be returned to an onshore LNG facility, as some of the BOG is combusted at the offshore marine terminal.

Abstract: Methods for removing sulfur from syngas in a Fischer-Tropsch reactor, and reactors including means for removing sulfur from syngas are disclosed. Sulfur-reactive metals can be used in the Fischer-Tropsch unit to sequester the sulfur. For example, the Fischer-Tropsch unit can be run in stages, using a sacrificial catalyst in a first stage to adsorb the sulfur. The Fischer-Tropsch reactor can include internal baffles that separate the reactor into zones, with a sacrificial catalyst in one or more of the zones, that can be easily sequestered and regenerated or replaced. Sulfur adsorbents can be placed in the inlet gas manifold. A portion of the Fischer-Tropsch catalyst can be converted into larger size pellets that do not fluidize with the firer grain Fischer-Tropsch catalyst and remain near the gas inlet where they adsorb and sequester the sulfur. These embodiments can be combined in any suitable manner to lower the sulfur concentration in the syngas feed. The resulting syngas feed preferably has a sulfur concentration less than 50 wppb, more preferably less than 15 wppb, and most preferably less than 1 wppb.

Abstract: A method and system for the downhole separation of a water and oil mixture and disposal of separated water utilizing a hydrostatic pressure head is disclosed. A separator apparatus is located in a wellbore at a depth substantially above a water disposal formation. A mixture of oil and water is received from an oil producing formation and delivered to the separator apparatus. The oil and water mixture is separated into separated water and separated oil by the separator apparatus. The separated oil is delivered to the well surface. The separated water is discharged from the separator apparatus into the wellbore creating a column of water above the water disposal formation. The hydrostatic pressure created by the column of water is ideally sufficient to cause the separated water to dissipate into the water disposal formation. Alternatively, an auxiliary disposal pump may also be used to augment the hydrostatic pressure in the wellbore to further cause dissipation of the separated water into the water disposal formation.

Abstract: The present disclosure provides a process for upgrading solid biomass feedstocks into more useable products. The process includes introducing a solid biomass feedstock, a liquid carrier, a slurry hydrocracking catalyst to a slurry hydrocracking zone in the presence of hydrogen and under slurry hydrocracking conditions to produce a slurry hydrocracking effluent comprising lighter hydrocarbonaceous products; wherein the liquid carrier is a hydrocracking recycle stream taken only from the slurry hydrocracking effluent; wherein the solid biomass feedstock and liquid carrier are combined upstream of the slurry hydrocracking zone to form a combined feed; the combined feed subsequently being introduced to the slurry hydrocracking zone.
