摘要： Catalyst particles and methods for making same are disclosed herein. The catalyst particles can include a ceramic support containing silica and alumina. The ceramic support can have a macropore concentration of about 15% to about 45%, a mesopore concentration of about 20% to 50%, and a micropore concentration of about 8% to about 30% based on the total pore volume of the ceramic support. The ceramic support can also have a surface area of about 0.5 m2/g to about 50 m2/g. The catalyst particles can have a long term permeability at 7,500 psi of at least about 10 D in accordance with ISO 13503-5.

摘要： A method for evaluating induced fractures in a wellbore includes obtaining a first set of data in a wellbore using a downhole tool. The method also includes pumping a first proppant into the wellbore after the first set of data is obtained. The first proppant includes a first tracer that is not radioactive. The method also includes pumping a second proppant into the wellbore. The second proppant includes a second tracer that is not radioactive. The second tracer is different than the first tracer. The first proppant and the second proppant flow into fractures in the wellbore. The method also includes obtaining a second set of data in the wellbore using the downhole tool after the first and second proppants are pumped into the wellbore. The method also includes comparing the first and second sets of data.

摘要： Lightweight proppant particles are disclosed. The lightweight proppant particle can include a proppant particle having an apparent specific gravity of at least about 1.5 g/cc, a coating of a hydrophobic material formed on an outer surface of the proppant particle, and a coating of an amphiphilic material formed on an outer surface of the coating of the hydrophobic material.

摘要： A method for producing an electrically-conductive pellet includes reducing a size of a first material. The method also includes wetting the first material to produce a first slurry. The method also includes introducing the first slurry into a fluidizer to produce a first pellet. The method also includes reducing a size of a second material. The second material is an electrically-conductive material. The method also includes wetting the second material to produce a second slurry. The method also includes applying the second slurry to the first pellet.

摘要： The present invention relates to methods for hydraulically fracturing a subterranean formation to improve the production rates and ultimate recovery by contacting unconsolidated resin-coated proppant particulates residing in a propped fracture with a reactive crosslinker in order to form a consolidated proppant pack. The present invention also relates to methods for use in water injection wells to consolidate the resin-coated proppant particulates in a gravel packed or frac packed region of a wellbore.

摘要： Born Scattering Inversion (BSI) systems and methods are disclosed. A BSI system may be incorporated in a well system for accessing natural gas, oil and geothermal reserves in a geologic formation beneath the surface of the Earth. The BSI system may be used to generate a three-dimensional image of a proppant-filled hydraulically-induced fracture in the geologic formation. The BSI system may include computing equipment and sensors for measuring electromagnetic fields in the vicinity of the fracture before and after the fracture is generated, adjusting the parameters of a first Born approximation model of a scattered component of the surface electromagnetic fields using the measured electromagnetic fields, and generating the image of the proppant-filled fracture using the adjusted parameters.

摘要： A method for evaluating induced fractures in a wellbore includes obtaining a first set of data in a wellbore using a downhole logging tool. A first proppant is pumped into the wellbore, after the first set of data is captured. The first proppant includes a first tracer that is not radioactive. A second proppant is also pumped into the wellbore, after the first proppant is pumped into the wellbore. The second proppant includes a second tracer that is not radioactive, and the second tracer is different than the first tracer. A second set of data is obtained in the wellbore using the downhole tool after the first and second proppants are pumped into the wellbore. The first and second sets of data are compared.

摘要： Methods for producing solid, substantially round, spherical and sintered particles from a slurry of a raw material having an alumina content of greater than about 40 weight percent. The slurry is processed to prepare green pellets which are sintered in a furnace with microwave energy at a temperature of 1480 to 1520° C. to produce solid, substantially round, spherical and sintered particles having an average particle size greater than about 200 microns, a bulk density of greater than about 1.35 g/cm3, and an apparent specific gravity of greater than about 2.60.

摘要： A composition and method for hydraulically fracturing an oil or gas well to improve the production rates and ultimate recovery using a porous ceramic proppant infused with a chemical treatment agent is provided. The chemical treatment agent may be a tracer material that provides diagnostic information about the production performance of a hydraulic fracture stimulation by the use of distinguishable both water soluble and hydrocarbon soluble tracers. The tracer can be a biological marker, such as DNA. The porous ceramic proppant can be coated with a polymer which provides for controlled release of the chemical treatment agent into a fracture or well bore area over a period of time.
