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 relate to recovering hydrocarbons by injecting into a reservoir outputs from two different types of steam generators along with carbon dioxide, enabling lower fuel consumption for such a hybrid-based approach versus either type of steam generator alone. One steam generator vaporizes water by thermal transfer from combustion with exhaust from the combustion remaining separated from the steam. Since this type of steam generator outputs a limited carbon dioxide concentration with the steam, at least part of the carbon dioxide injected comes from recycling the carbon dioxide separated out of production fluids recovered from the reservoir. Another steam generator produces the steam by direct water contact with combustion products to produce a resulting fluid including the steam and additional carbon dioxide.

Abstract: Methods for processing seismic data are described. The method includes: obtaining seismic data; solving a series of partial differential wave equations, wherein a first partial differential wave equation describes propagation of a seismic wave going from a first reflector to a second reflector, wherein a second partial differential wave equation describes propagation of a seismic wave going from a second reflector to a third reflector, and wherein a third partial differential wave equation describes propagation of a seismic wave going from a third reflector to a seismic receiver, wherein outputting predicted internal multiples for further imaging or attenuation.

Abstract: The present invention discloses a method of plugging a well that relies on casing expansion to plug uncemented casing sections, rather than milling out the casing or perforate wash and cement (PWC).

Abstract: A semi-closed loop system for producing liquefied natural gas (LNG) that combines certain advantages of closed-loop systems with certain advantages of open-loop systems to provide a more efficient and effective hybrid system. In the semi-closed loop system, the final methane refrigeration cycle provides significant cooling of the natural gas stream via indirect heat transfer, as opposed to expansion-type cooling. A minor portion of the LNG product from the methane refrigeration cycle is used as make-up refrigerant in the methane refrigeration cycle. A pressurized portion of the refrigerant from the methane refrigeration cycle is employed as fuel gas. Excess refrigerant from the methane refrigeration cycle can be recombined with the processed natural gas stream, rather than flared.

Abstract: A method of fracking carbonate-rich reservoirs, comprising injecting a cryogenic or chilled fluid followed by an acid into the reservoir, allowing the acid to etch the reservoir, and thereby increasing production of a fluid, such as water, oil or gas, from the reservoir. Further, injecting a preflush into the reservoir and later injecting a postflush into the reservoir to displace the acid from the tubulars into the reservoir.

Abstract: A method for modeling reservoir souring using object-oriented numerical solutions separate from reservoir topography is described. Specifically, flow physics are separated into one or more objects, along with one or more H2S generation mechanisms, for modeling on time and spatial scales separate from field scale modeling

Abstract: The present disclosure relates to a particularly effective well configuration that can be used for SAGD and other steam based oil recovery methods. Fishbone multilateral wells are combined with SAGD, effectively expanding steam coverage, but the fishbones are preheated to mitigate plugging problems, with e.g., resistive heating, EM heating or chemical heating.

Abstract: Methods of analyzing and optimizing a seismic survey design are described. Specifically, the sampling quality is analyzed as opposed to the overall quality of the whole survey. This allows for analysis of the impact of the offsets, obstacles, and other aspects of the survey on the sampling quality, which will improve the ability to compress the resulting data and minimize acquisition footprints.
