Abstract: A workflow for data acquisition and processing to quantify immobile and producible fluids more accurately from log and core measurements is described. Also described are methods of reservoir characterization to distinguish producible from immovable fluids that use NMR measurements on core samples as endpoint references and calibration points for downhole logging. Endpoint signatures of pore fluids are easily identified by the NMR of core samples, thus providing more accurate results on formation fluid porosities and saturations from measured data.

Abstract: Methods and systems for disposing of fluids, such as brine or produced water or CO2, in a disposal well that requires the injection well to be seismically monitored is described. Injection continues until a seismic event of threshold value caused by the injection is detected. The first injection point is then closed until the first event dissipates (e.g., pressure is reduced). Meanwhile, fluid is injected into an open injection point, again until a second seismic event is detected. Then the second injection point is closed and a third injection point (or the first if sufficiently dissipated) is opened and used for injection, and so on. In this way, the seismic risk is greatly reduced.

Abstract: A solvent is dispersed into a natural gas feed at a solvent injection point to produce a mixed feed. The mixed feed contains heavy components with a potentially fouling portion that can cause obstructions in a heat exchanger. A fluid injection system can inject the solvent intermittently, for instance, based on an amount of accumulation or expected accumulation of heavy component solids in the heat exchanger. The solvent prevents the potentially fouling portion of the heavy components from freezing, melts or dissolves the accumulation, and reduces the obstructions in the heat exchanger. The fluid injection system includes a solvent supply, an optional atomizer, an injection controller, optionally one or more sensors, and/or optionally a heater. The solvent injection system can disperse the solvent onto a flow surface for the natural gas feed and/or mixed feed to form a solvent film which further reduces heavy component solids.

Abstract: Implementations described and claimed herein provide systems and methods for a data management tool for accessing various databases and data sources to collect or obtain data associated with a user of the tool or a member of an organization. The data management tool may include a user interface for receiving information or inputs from a user, such as a custodian of the data, to determine the various databases and/or systems from which user data may be available. To access the user data, the data management tool may communicate with various sources or gateways to sources, such as cloud-based data storage systems, operating system gateway programs, user hardware gateway programs, and the like. Various databases storing user data may be accessible through the systems or gateways and the data management tool may request such data in response to one or more instructions received via the user interface.

Abstract: The disclosure describes a method to indirectly measure the amount of elemental sulfur or amorphous dithiazine in a reservoir sample by converting them to H2S gas. The H2S is captured via caustic cyanide solution and quantified by analytical methods and correspond to the concentration of elemental sulfur or amorphous dithiazine. The method has particular applicability to determine where best to drill and avoid locations of high sulfur.

Abstract: A method of monitoring deposits on a well by cleaning a well of existing deposits sufficiently to allow a plunger from an instrumented plunger lift to travel therethrough; monitoring any further addition of deposits using the same instrumented plunger lift that records a velocity and a position of the plunger (or any other parameters that allows one to estimate speed and depth) as it travels through the well; and using the recorded velocity and position to determine a size and a position of each added deposit by a decrease in the velocity at a given position as compared to a baseline velocity. Ideally, once added deposits begin to impinge on production rates, the operator then treats said well to remove each said added deposit. The technology may thus be used to identify potential deposits, but also use to validate the efficacy of chemical treatments used in said well.

Abstract: Methods for using shut-in pressures to determine uncertainties in a hydraulic fracturing process in a shale reservoir are described. Data commonly collected during multistage fracturing is used to calculate propped fracture height and induced stresses, as well as other variables, in the presence of horizontal stress anisotropy. These variables can then be incorporated into reservoir simulations to improve the fracturing monitoring, forecast hydrocarbon recoveries, or modify fracturing plans.

Abstract: An economical process in which cement sheath integrity, perforation cluster spacing and frac plug integrity can be assessed for every frac stage, potentially leading to improvements in stimulation, completion, cementing and drilling practices. It is based on analyzing wellbore pressure responses occurring at key segments of the wireline pump-down and perforating operation and correlating the results among multiple frac stages and wells in a field or play. A special requirement is that the frac ball (ball check) is inserted in the frac plug and pumped to seat prior to performing perforating operations. A complementary benefit of this process is that selectively establishing injectivity in the most distant perforation cluster can be used to establish inhibited HCl acid (wireline acid) coverage across all perforation intervals for uniform reduction in near-wellbore tortuosity.

Abstract: A method of predicting production characteristics of a hydrocarbon well using time lapse geochemistry fingerprinting and using machine learning to train a reservoir model to accurately predict production characteristics.

Abstract: Implementations described and claimed herein provide systems and methods for processing liquefied natural gas (LNG). In one implementation, a dry feed gas is received. The dry feed gas is chilled with clean vapor from a heavies removal column to form a chilled feed gas. The chilled feed gas is partially condensed into a vapor phase and a liquid phase. The liquid phase retains freezing components. The freezing components are extracted using a reflux stream in the heavies removal column. The freezing components are removed as a condensate. The vapor phase is compressed into a clean feed gas. The clean feed gas is free of the freezing components for downstream liquefaction.

Abstract: In the process of suspending a subsea hydrocarbon well (1) after finalizing the completion operation and prior to stimulation of the well and putting the well on production, preinstalled upper and lower glass plugs (11, 12) are used as temporary barriers in the tubing. The plugs allow various tests to be performed before the lower plug (12), below the production packer (10), is broken; the upper plug (11) located above the downhole safety valve (13) then forms one of the barriers required to suspend the well whilst the Blow Out Preventer (BOP) is removed and Xmas tree installed, at which point the upper plug (11) is broken.

Abstract: Method of cleaning sucker rods using a portable cleaning tool containing a rotating brush assembly to remove scale and corrosion residue on the sucker rods is described herein. The brush is annular with an empty or hollow center, such that the rod can penetrate through the hole in the brush. The tool is powered by air compression, and also contains a mechanism of removing the collected debris for disposal. The cleaning tool assembly could be either a standalone device on site placed on a mounted rack, or could be attached to the rod to be cleaned.

Abstract: Systems and methods of forming a seal employ a robust metal sealing unit for tubulars used in rotary drilling. Specifically, eutectic alloy is used to seal a tubular to a wellbore after drilling. A downhole heater melts the alloy, allowing the alloy to expand and drain before it cools and solidifies between the wellbore and tubular, forming a gas tight seal.

Abstract: Buoyancy modules filled with gases lighter than ambient air are described that are used to lift hoses and other lines off the surface of the ground. These buoyancy modules can support any line above the ground, the line delivering a fluid or energy from a source to a target.

Abstract: The present disclosure generally relates to harvesting geothermal energy from mature and near end-of-life oil and gas reservoirs that have been subjected to secondary oil recovery steam processes like steam-assisted gravity drainage (SAGD), steamflood, etc. The geothermal potential of these mature SAGD reservoirs can be used to generate green electricity thus reducing the greenhouse gas (GHG) footprint of the oil production. Lateral spacing of injectors and producers, with closing of unused members of a well-pair for energy recovery is described.

Abstract: A method for producing heavy oil while reducing steam usage, the method including producing oil by SAGD or a SAGD variant in an array of wellpairs until an SOR increases, then shutting in every other injector and injecting steam plus noncondensable gas (NCG) in the remaining injectors and producing oil from all producers.

One method involves injecting a fluid into an active well of the subterranean formation at a pressure sufficient to induce one or more hydraulic fractures. Measuring, via a pressure sensor, a poroelastic pressure response caused by inducing of the one or more hydraulic fractures. The pressure sensor is in at least partial hydraulic isolation with the one or more hydraulic fractures.
