| ENHANCED OIL RECOVERY TECHNOLOGY USING COMPOSITIONS BASED ON CELLULOSE ETHERS |
| This technology, using compositions based on cellulose ethers, provides an increase of reservoir sweep due to partial or complete blocking of watercut high permeability formations and subsequent redistribution of flood front. Polymer compositions based on ethers, cellulose-methylcellulose, carboxymethilcellulose, oxyethilcellulose, etc. are used to create an impermeable or low permeable barrier to filtration. The technology is used at late stage of development of oil fields, comprising heterogeneous as to permeability, reservoirs. The technology is widely introduced in oil fields of Tatarstan Republic during 10 years. About 2 min. of additionally produced oil has been obtained as a result of introduction. Specific technological efficiency makes up 400-500 t of additionally produced oil per one ton of injected reagent. |

| APPLICATION OF THE TAPE POLYTERM IN COMBINED PROTECTIVE COATING ON THE BASE OF BITUMEN POLYMER MASTIC |
| It is designed for anticorrosion protection of steel underground long distant oil pipelines (diameter - up to 1 220 mm included) at their major repairs under the operating temperature not higher than +40°C.
Combined coating is formed out of bitumen polymer priming (primer), a layer of bitumen polymer mastic and thermo-shrinking tape. It is carried out directly on the place of pipeline installation in the ditch on the surface of pipeline. |
|
| MASTIC POLYMER BITUMEN 'MPBT' |
| Mastic polymer bitumen tape (MPBT) is designed for corrosion protection of outside surface of steel underground oil- and gas pipelines at their repair at temperature up to + 40°C.
Mastic tape is made by a method of application of a mastic on a polymer film from polyvinylchloride (PVC) or from a material on the basis of modified polyethylene. |

| HIGH GOR BOTTOMHOLE PUMPING UNIT |
| The Unit provides satisfactory complete separation of oil from gas (at gas content 100 cub.m/cub.m and over), controls annulus pressure and gas flow through the annulus. It creates optimal conditions for bottomhole pump operation, reduces possibility of forming gas hydrates and wax deposits, and increases oil production. |
|
| POLYMER-THERMAL TREATMENT TECHNOLOGY |
| The Technology allows to increase a layered-nonhomogeneous reservoir treatment coverage by leveling-off filter resistance of various permeability laminas due to residual resistance factor.
It allows to ultimate oil recovery increase for 5 - 6% with heat carrier economy of 8 -10%. |
|
| HIGH GOR FLOW PRODUCTION UNIT |
| The unit prevents wax deposits, provides for coordination in "formation — well — oil-flow pipeline" system operation and increases oil production. |
|
| HYDROMECHANICAL SLOT PERFORATION |
| Secondary completion technology with 60, 73 mm diameter tubing run perforator geophysically linked to cross-section allows forming large-length longitudinal split with roll-on disk (all-point loading metal plastic deformation principle) in the required casing interval, and washing a cavity with fluid jetting in the cement ring and rock. |
|
| INSULATION CONTROL DEVICE |
| Insulation quality control device is used to control quality of electric cable and electric motor insulation at the wells equipped with submersible centrifugal pump units at environment temperatures down to -40°C. |
|
| OIL AND GAS PIPELINES REPAIR EQUIPMENT |
| Reconstruction
and repair of petroleum-and-gas sites, first of all, pipeline systems to
increase their efficiency, reliability and ecological safety have become one of
priority directions in pipe-line transport today. |
|
| FLOW-TYPE INDUSTRIAL GAS CHROMATOGRAPH |
| This new industrial chromatograph provides for a
combination of its blast-resistance with its small dimensions and mass which is
explained by the fact that there is no need in using additional gases, with
power consumption reduced 10-20 times. |
