    Abstract: A seismic sensor includes an outer housing having a central axis, an upper end, a lower end, and an inner cavity. In addition, the seismic sensor includes a proof mass moveably disposed in the inner cavity of the outer housing. The outer housing is configured to move axially relative to the proof mass. Further, the seismic sensor includes a first biasing member disposed in the inner cavity and axially positioned between the proof mass and one of the ends of the outer housing. The first biasing member is configured to flex in response to axial movement of the outer housing relative to the proof mass. The first biasing member comprises a disc including a plurality of circumferentially-spaced slots extending axially therethrough. Still further, the seismic sensor includes a sensor element disposed in the inner cavity and axially positioned between the first biasing member and one of the ends of the outer housing. The sensor element includes a piezoelectric material configured to deflect and generate a potential in response to the axial movement of the outer housing relative to the proof mass and the flexing of the first biasing member.

    Abstract: The material for proppant and method for producing the same relate to the chemistry of high-molecular weight compounds, and more particularly, to polymer materials with high requirements for physical and mechanical properties, for instance, for the production of proppants, i.e., propping granules, used in the oil and gas production by a method of hydraulic fracturing of formation. The technical result achieved by implementation of the present invention is an increase in thermal strength of the proppant material providing for a compressive strength of at least 150 MPa at a temperature of not less than 100° C. The method consists in the following. A mixture of oligocyclopentadienes is obtained by heating dicyclopentadiene (DCPD) to a temperature of 150-220° C. and holding at this temperature for 15-360 minutes. The oligomerization of dicyclopentadiene occurs. The mixture of oligomers is cooled down to 20-50° C., and polymer stabilizers, radical initiators, methacrylates and a catalyst are sequentially added thereto. The resultant polymer matrix is heated up to a temperature of 50-340° C. and is held at this temperature for 1-360 minutes, and thereafter is cooled down to room temperature. A metathesis polymerization (MP) and radical polymerization (RP) cross-linkage of the mixture of oligocyclopentadienes with methacrylic esters occurs.

    Abstract: The invention relates to the field of membrane gas separation and can be used for the energy-efficient fractionation of hydrocarbon mixtures, including separation and drying of natural and associated petroleum gases. Proposed is a method of fractionating mixtures of low molecular weight hydrocarbons which is based on the capillary condensation of the components of a mixture in the pores of microporous membranes with uniform porosity and a pore diameter in a range of 5 to 250 nm, wherein, for capillary condensation, the temperature of the membrane and the pressure on the permeate side are kept below the temperature and the pressure of the feed mixture such that the equilibrium pressure of the saturated vapors of the separated components on the permeate side is lower than the partial pressure of the components in the feed stream. This method makes it possible to significantly increase membrane permeability with respect to condensable components (over 500 m3/(m2·atm·h) for n-butane), and also component separation factors (the n-C4H10/CH4 separation factor is greater than 60 for a mixture having an associated petroleum gas composition), while also making it possible to dispense with deep cooling of the gas stream fed to a membrane module, and to carry out gas separation under insignificant cooling of the membrane on the permeate side (down to −50° C.) For more effective gas separation, permeate is collected in a liquid state. A technical effect of the invention resides in providing a method that makes it possible to efficiently remove high-boiling hydrocarbons (C3-C6) from natural gas and associated petroleum gases, as well as to obtain gas mixtures with a constant composition.

    Abstract: The increased thermal strength polymer proppant and method for producing the same relate to the oil and gas production technology using materials of high-molecular compounds, especially to proppants of polymer materials with high requirements for the physical and mechanical characteristics, utilized as propping granules in the oil and gas production by a method of hydraulic fracturing. The proppant is made of a metathesis-radically cross-linked mixture of oligocyclopentadienes and methylcarboxy norbornene esters. The proppant represents microspheres having a roundness and sphericity of at least 0.9 for no less than 80% by weight, whose average size being in the range 0.25-1.1 mm and a bulk density being in the range of 0.5-0.7 g/cm3. The technical result is an increase in thermal strength of the proppant material, providing for a compressive strength of at least 150 MPa at a temperature of not less than 100° C.

    Abstract: The invention relates to gas analysis and to combustible gas and vapour analyzers based on a thermocatalytic operating principle. The subject of the invention is a sensor the sensitive elements of which are manufactured by planar techniques that can be easily automated. The main distinguishing feature is that a working sensitive element and a reference sensitive element are colocated in a single micron-sized structural component (a microchip) on a common substrate made of porous anodic aluminium oxide. The design of the sensitive elements provides for film-wise heat transfer from heated parts of the working and reference sensitive elements. Measuring microheaters which heat the working and reference sensitive elements up to working temperatures and provide for differentially measuring an output signal in a measuring bridge circuit are spaced apart at opposite sides of the anodic aluminium oxide substrate and are disposed on arms projecting beyond the common substrate configuration. The sensitive elements are disposed in a reaction chamber having restricted diffusion access via a calibrated orifice, and the diameter of regular pores in the microchip substrate is increased to sizes that provide for a predominantly molecular diffusion mode in the pores (100 nm or more).
