Systems and methods presented herein provide for a screw conveyor adsorption moving bed that separates carbon dioxide from a gas mixture. Adsorbent particles are transported between an adsorption section of the reactor, which can be an outer column, and a desorption section, which can be an inner column. The particle transport is facilitated by the screw conveyor located inside the inner column. The screw conveyor is specially designed to have a hollow screw, shaped as a spiral surface, attached to a central shaft. The screw surface is also equipped with plurality of holes and a flexible edge attachment to seal against the cylindrical surface. The hollow shape allows the gas to flow from the inlet of the shaft to the particles through the holes on the screw, thus creating uniform gas distribution.

Screw conveyor adsorption moving bed with heat integration

Systems and methods presented herein provide for a box chain conveyor adsorption moving bed that separates carbon dioxide from a gas mixture. A box chain conveyor is oriented around a wall, including a chain that moves in a closed loop around the wall. One side of the box chain conveyor is in an adsorption section and an opposite second side is in a desorption section. Particle boxes contain adsorbent particles, and the chain moves the particle boxes around the wall in the closed loop. Heated gas passes through the desorption section, causing COto desorb from particle boxes in the desorption section. Desorbed COis expelled from an output.

A system and method for treating a subterranean formation. The method may include utilizing a diluted stream and a high-loading stream which are combined to form a diverting composition. The diverting composition may then be injected into a wellbore. The system may include devices to prepare the diluted stream and high-loading stream, combine the streams, and introduce the combined stream into the wellbore.

System and method of treating a subterranean formation with a diverting composition

A slurry for treating a wellbore, comprising a base fluid and a plurality of pre-processed fiber flocks dispersed in the base fluid.

Pre-processed fiber flocks and methods of use thereof

A device includes a housing having a bore formed axially therethrough. The housing includes a stop that protrudes radially inward proximate to a lower end of the housing. The device also includes a lower piston positioned in the bore. The lower piston is configured to move axially within the bore in response to a pressure differential across the lower piston. The lower piston is prevented from passing out through the lower end of the housing by the stop. The lower piston has a lower piston hole formed therethrough. The device also includes an upper piston positioned in the bore. The upper piston is configured to move axially within the bore in response to a pressure differential across the upper piston. The upper piston has an upper piston hole formed therethrough. The device is configured to receive a fluid in the bore, between the upper and lower pistons.

System and method for measuring properties of a fluid

Methods of treating a subterranean formation are disclosed that include introducing a treatment fluid including shaped particle and/or shaped uniform particles into a subterranean formation via a wellbore, and creating a plug including the shaped particle and/or shaped uniform particles of the treatment fluid.

Methods of zonal isolation and treatment diversion with shaped particles

Methods of treating a subterranean formation penetrated by a well bore, by providing a treatment fluid comprising a blend including a first amount of particulates having a first average particle size between about 3 mm and 2 cm and a second amount of particulates having a second average size between about 1.6 and 20 times smaller than the first average particle size or a second amount of flakes having a second average size up to 10 times smaller than the first average particle size; by introducing the treatment fluid into the well bore; and by creating a plug with the treatment fluid.

Methods of zonal isolation and treatment diversion

A fracture treatment method includes forming propped regions having an optimized conductivity. Also disclosed are systems to treat a fracture interval and to produce reservoir fluids from a formation.

Fractures treatment

Method and system for multi-stage well treatment wherein an isolating device is tethered with a distributed measurement cable during the treatment of one or more stages. The cable having a cable core including an optical fiber conductor.

Methods and cables for use in fracturing zones in a well

Methods of performing a stimulation operation at a wellsite are disclosed. The wellsite is positioned about a subterranean formation having a wellbore therethrough and zones thereabout. The method involves establishing at least one objective for stimulating production of reservoir fluid from the subterranean formation and into the wellbore. The stimulating involves placing a stimulating fluid along the zones of the wellbore. The objective is based on wellsite data. The method also involves identifying at least one constraint for the stimulating, determining target distributions of the stimulation fluid based on the objective(s) and the constraint(s), and selecting operational parameters for the stimulating based on the constraint(s) and the target distributions. The method may also involve stimulating the subterranean formation using the target distributions and the operational parameters, monitoring the wellsite during the stimulating, and adjusting the stimulating based on the monitoring.

Method for wellbore stimulation optimization

Methods of treating a subterranean formation penetrated by a well bore, by providing a treatment fluid comprising non-homogeneous particulates including a degradable material and a stabilizer; by introducing the treatment fluid into the well bore; and by creating a plug with the treatment fluid.

Well treatments for diversion or zonal isolation

An apparatus includes a string that extends into a well and a tool that is disposed in the string. The tool is adapted to form a seat to catch an object communicated to the tool via a passageway of the string in response to the tool being perforated.

The method allows employing proppant surface modification with the emulsified treatment material for proppant delivery deep into far-field fracture zone during operations of hydraulic fracturing or heterogeneous proppant placement via proppant aggregation. In the case of gravel packing operations, to maintain the circulation of the proppant slurry for homogeneous proppant settling to the desired wellbore location. The emulsified treatment material can be degradable of non-degradable in downhole conditions.

Method for modification and delivery of proppant during well operations, method for hydraulic fracturing and method for gravel packing

Methods for treating subterranean wells in which the producing formation is a carbonate comprise preparing a treatment fluid comprising either: (a) an aqueous solution of a multivalent-cation reacting polymer; (b) a solution comprising a fatty acid and an ethanolamine; (c) an aqueous acidic solution of one or more compounds whose calcium salts are insoluble; or (d) an aqueous solution comprising urea or alkane derivatives thereof or both and polyvinylpyrrolidone (PVP). The treatment fluid is placed in the well such that the solution contacts the carbonate formation at a pressure lower than the fracturing pressure. The treatment fluid is allowed to react with the carbonate formation, thereby depositing a film onto the formation surface or part of the formation surface. Then an acid solution is placed in the well such that the acid contacts the carbonate formation at a pressure lower than the fracturing pressure.
