Abstract: The present disclosure describes the use of growth models and data driven models that are combined for quickly and efficiently modeling SAGD reservoir oil production. Growth function surrogate models are used for efficient and reliable reservoir modeling and production forecasting as opposed to CPU intensive simulations based on finite difference models. A data-driven technique can then compare the growth function surrogate model with real field data to find discrepancies and inconsistencies between the two, allowing for an updates and improvements of the growth function model.

Abstract: The invention is directed to polymers that self-crosslink at acidic pH or can be crosslinked by phenolic agents in brine. Such polymers have lower viscosity and can be pumped deep into reservoirs, where they will cross link in situ, thus increasing their viscosity and/or form a gel and blocking thief zones. Methods of making and using such polymers are also provided.

Abstract: Systems and methods utilize heated waste flue gas to treat water. The heated waste flue gas, which may come from a steam generator, bubbles through untreated water to vaporize the untreated water and separate out solids and other contaminants before subsequent condensing. The steam generator may receive resulting treated water to produce steam for injection.

Abstract: A core-in-shell heat exchanger, a method of fabricating the core-in-shell heat exchanger, and a method of exchanging heat in a core-in-shell heat exchanger disposed on a slosh-inducing moving platform are described. The method of exchanging heat includes introducing a shell-side fluid into a shell of the core-in-shell heat exchanger and introducing a fluid to be cooled into each of one or more cores of the core-in-shell heat exchanger, the one or more cores being arranged along an axial length of the shell with a plurality of baffles disposed on either side of the one or more cores along the axial length of the shell to reduce slosh of the shell-side fluid. The method also includes draining excess shell-side fluid using a plurality of drains, at least two of the plurality of drains being disposed on opposite sides of one of the plurality of baffles.

Abstract: A process is provided for the time dependent reduction and kill of cellular bacteria in a fluid by sequential exposure to nitrites and a low concentration of biocide. Oilfield water containing sulfate-reducing bacteria can be supplied with a timed sequential exposure of nitrite and biocide. The timed sequential addition of the biocide following exposure to the nitrite provides enhanced kill of the sulfate-reducing bacteria at concentrations of biocide that are lower than would be possible using simultaneous addition of these materials.

Abstract: A system and method to identify a dysfunction of a drill-string within a wellbore are provided. The system includes a sensor positioned proximate to a drill-string and proximate to a surface of the wellbore. The sensor is configured to sense a surface condition and generate measurement data. The system also includes a transmitter in communication with the sensor and configured to transmit the measurement data. The system also includes a receiver configured to receive the measurement data from the sensor. The system also includes a processor configured to calculate a downhole measurement based on the measurement data and analyze the downhole measurement to identify the dysfunction.

Abstract: A method is provided to determine and mitigate one or more downhole events of a drill string in a wellbore. The method includes receiving, via a processor, drilling data from one or more surface sensors. The drilling data is processed into a plurality of segments. Each of the plurality of segments are processed by a pre-trained model such that one or more labels are determined. The one or more labels are relating to one or more downhole events corresponding to each of the plurality of segments.

Abstract: A tool designed for manipulation by an operator from a safe position out of line with the pig receiver opening in case an equipment failure or inadvertent opening of the trap before complete depressurization thereof should cause the pig to eject from the open end of the receiver. The tool features two main components, primarily a reaching assembly of substantially linear configuration having an elongated shape whose length runs along a first longitudinal axis, which lies generally parallel with a central longitudinal axis of the trap barrel during use of the tool, and support assembly that projects laterally from the reaching assembly in a direction generally perpendicular thereto so as to extend along a transverse axis that extends radially of the longitudinal axis.

Abstract: A method of drilling a first well and a second well into the reservoir includes forming a conduit between the first well and the second well. The conduit is filled with a conduit material. Finally, a low viscosity fluid is injected into the conduit to establish fluid communication between the first well and the second well.
