Abstract:
A process for in situ thermal recovery of hydrocarbons from a reservoir is provided. The process includes: providing an oxygen-enriched mixture, fuel, feedwater and an additive including at least one of ammonia, urea and a volatile amine to a Direct-Contact Steam Generator (DCSG); operating the DCSG, including contacting the feedwater and the additive with hot combustion gas to obtain a steam-based mixture including steam, CO2 and the additive; injecting the steam-based mixture or a stream derived from the steam-based mixture into the reservoir to mobilize the hydrocarbons therein; and producing a produced fluid including the hydrocarbons.
Abstract:
Systems and methods for controlling the inflow of materials into a production well during recovery of hydrocarbons from a hydrocarbon-containing reservoir. The system includes a flow control device configured to limit steam flow and hot water flow from the hydrocarbon-containing reservoir.
Abstract:
A method and device for in-line injecting of flocculated agent into a fluid flow of mature fine tailings (MAT). The method includes the steps of: a) providing a fluid flow of mature fine tailings to be treated along a given channel fluidly connected to the pipeline; b) providing a source of flocculating agent; and c) introducing flocculating agent inside the fluid flow of mature fine tailings via a plurality of injection outlets for injecting the flocculating agent into the fluid flow in a dispersed manner so as to increase an exposed surface area of the injected flocculating agent and thus increase a corresponding reaction with the mature fine tailings, for an improved flocculation of said mature fine tailings, and/or other desired end results. Also disclosed is a kit with corresponding components for assembling the in-line injection device to be connected in-line with the pipeline carrying the mature fine tailings to be treated.
Abstract:
The present disclosure generally relates to upgrading difficult to process heavy-oil. In particular, the disclosure relates to upgrading heavy oil and other high carbon content materials by using an integrated thermal-process (ITP) that utilizes anti-coking management and toluene insoluble organic residues (TIOR) management to directly incorporate lighter hydrocarbons into high molecular weight, low hydrogen content hydrocarbons such as thermally processed heavy oil products. This process can be integrated with other thermal processing schemes, such as cokers and visbreakers, to improve the conversion and yields from these integrated processes.
Abstract:
The following provides a system and method to predict an indicator of tube fouling in a fired apparatus such as a boiler. Historical data can be collected when the tubing is still considered to be clean, and used to build a first model between an indicator of fouling, such as tube skin temperature, and boiler load. The actual measurement of that indicator of fouling can then be compared against the model output, such that the error between the model and measurement is considered an indication of the tube fouling. Moreover, the rate of change of the model error can be used to measure the fouling rate. Next, historical data on the fluid feed quality can be collected and together with the historical error rate change data can be combined to develop a second model. This second model reflects how fluid feed quality variables may affect the fouling rate over time.
Abstract:
Methods are described for the production of a hydrocarbon product and selective rejection of low quality hydrocarbons from a bitumen-containing material, where product quality, production yield, processing input requirements, and environmental benefits are assessed for selecting a candidate method for deployment. The methods facilitate selection and deployment of sustainable hydrocarbon production operations rather than focusing on maximizing volumetric yield of hydrocarbons.
Abstract:
A system and method are provided for monitoring a piping network. The method includes obtaining data comprising temperature, displacement, and vibration measurements from a plurality of sensor assemblies. The sensor assemblies are selectively installed at a plurality of locations in the piping network, and the piping network is subjected to at least one multi-phase flow effect during its operation. The method also includes analyzing the data using at least one model to: predict pipe life, detect an operational or pipe damage event, and/or trigger preventative maintenance.
Abstract:
A method is provided for the treatment of waste streams resulting from the processing of hydrocarbons that contain naphthenic acids, for example desalter brine resulting from the extraction or production of hydrocarbons from an oil sands reservoir. Naphthenic acids can be removed from these streams by removing oil-wet solids from the waste stream prior to conventional waste water processing, and the oil-wet solids can further be independently remediated to reduce naphthenic acid concentration for disposal.
Abstract:
Oil-in-water fungicidal formulations are prepared having pigment dispersed therein, the pigment being stable within the oil-in-water emulsion as a result of the addition of suitable silicone surfactants and suitable emulsifiers. The formulations can be prepared either as a 2-pack formulation or as a single formulation. In the case of the single formulation polyethylene glycol is also added. In either case, the formulations show a synergistic effect through the addition of the pigment, the resulting formulations having an increased efficacy. Further, the formulations show a synergistic effect when mixed with conventional chemical fungicides, both being added in reduced amounts compared to recommended rates.
Abstract:
There is provided a method for effecting at least partial interference of a fluid passage extending between a casing, disposed within a wellbore that is penetrating a subterranean formation, and the subterranean formation. The method includes detecting the fluid passage, and effecting an operative displacement of a casing section of the casing such that at least partial interference of the fluid passage is effected.
