A fluid control device includes a filtration component, which has a porous filtration medium. The filtration medium contains a shape memory thermoset material foamed with a polymeric microsphere and a gas-producing chemical foaming agent. The porous filtration medium is configured to be compacted from an initial shape to a compacted shape, deployed in the borehole, and subsequently expanded to conform to a surface of the borehole.

Methods may include calculating a formation permeability for a subterranean formation from a combination of dielectric measurements and acoustic measurements, wherein the formation permeability is calculated according to the formula: k.sub.g=a(V.sub.xσ.sub.w/ε.sub.r).sup.b, where V.sub.x is either V.sub.p, V.sub.s, or V.sub.p/V.sub.s, σ is formation conductivity, Ø.sub.w is water-filled porosity, and a and b are constants that are empirically determined for the frequency selected with respect to V.sub.x; and creating a design for a wellbore operation from the calculated formation permeability. Methods may also include obtaining a dielectric measurement from a downhole formation; obtaining an acoustic measurement from a downhole formation; and calculating a formation permeability from a combination of the dielectric measurement and the acoustic measurement.

A method of identifying hydrocarbon production information is disclosed. In in a first hydrocarbon management environment, a first audio signal is detected and a characteristic acoustic fingerprint is identified therefrom. The fingerprint is stored in a memory, along with identifying information associated with the first signal. A second audio signal is detected and a characteristic acoustic fingerprint is identified therefrom. The fingerprints are compared, and if the fingerprints match the identifying information of the first audio signal is assigned to the second audio signal. A notification regarding the matching of the characteristic acoustic fingerprints of the first and second audio signals is issued.

A method for fracking a hydrocarbon formation. An actuating member, flowable along a production string, is provided. A unique key portion thereon engages a desired sliding sleeve covering an associated port in the production string. Applying uphole fluid pressure causes the sliding sleeve and actuating member to move so as to uncover the associated port. After fracking and cessation of supply of pressurized fracturing fluid, a compressed spring on the actuating member decompresses so as to reposition a sand screen immediately beneath the port so as to prevent sand from flowing into the production string. Flowable insertion of additional “keyed” actuating members allows similar opening of additional successive uphole ports and fracking in the regions of such additional opened ports, with similar location of sand screens at each opened port. Plug members on each actuating member thereafter dissolve or are successively burst to thereby allow production.

Methods for treating a formation may include introducing components of a treatment solution into a wellbore such that the treatment solution contacts the formation to be treated, where the treatment solution may include urea, urease, a calcium ion source, one or more polysaccharides, a casein protein, a protease, an ionic compound, and a sugar, where the formation may have an amount of sand production before treatment and may be in fluid contact with the wellbore, and where an amount of sand production after treatment may be less than the amount of sand production before treatment. Consolidated sand structure compositions may include previously unconsolidated sand interlinked by inter-particle cementitious bonds comprising deposited calcium carbonate crystals, where the consolidated sand has a structural strength and the consolidated sand structure is porous to permit fluid flow through the composition.

A method for determining properties of a laminated formation traversed by a well or wellbore employs measured sonic data, resistivity data, and density data for an interval-of-interest within the well or wellbore. A formation model that describe properties of the laminated formation at the interval-of-interest is derived from the measured sonic data, resistivity data, and density data for the interval-of-interest. The formation model represents the laminated formation at the interval-of-interest as first and second zones of different first and second rock types. The formation model is used to derive simulated sonic data, resistivity data, and density data for the interval-of-interest. The measured sonic data, resistivity data, and density data for the interval-of-interest and the simulated sonic data, resistivity data, and density data for the interval-of-interest are used to refine the formation model and determine properties of the formation at the interval-of-interest. The properties of the formation may be a radial profile for porosity, a radial profile for water saturation, a radial profile for gas saturation, radial profile of oil saturation, and radial profiles for pore shapes for the first and second zones (or rock types).

A method for improving the stability of reservoir rock in bottomhole zones of wells to destructive loads developing during operation of wells at oil and gas fields during operation at underground gas storages is disclosed. Prior to running of casing string in zone of contact of productive formation with its impenetrable roof it is proposed to drill or blur cone-shaped cavern with vertex facing the formation, the cavity parameters must satisfy the conditions according to the depth of the cavity counted from the well wall along the contact line of the productive formation and its impermeable roof should exceed 4 cm, and the angle between the cone generatrix and the casing pipe generatrix within the range of values from 5° up to 30°. This will increase well bottomhole zone stability to destructive loads developing in process of its operation and reduction of volumes of broken rock carried to well bore.
