The paper considers the methods, equipment and results of landslide monitoring. Monitoring systems, covering early warning of a landslide threat that may trigger an emergency, are based on registration, analysis and processing of versatile information, including geophysical surveys, regime geotechnical, hydrometeorological and seismic observations. In the monitoring process, the technology and equipment used to obtain the above-mentioned data play an important role.

Based on studies on the interaction and heat resistance of some heat-resistant polymer additives at 128 °C, a sulfonated polyacrylamide polymer AN-125 is proposed as an additive for improving the viscosity of a surfactant composition. The results of experimental studies of a new surfactant composite prepared based on a mixture of ethoxylated and propoxylated sulfate, α-olefin sulfonate and alkylphenol ethoxylate with a concentration of 500 ppm and additives to improve the viscosity in the reservoir model from the deposit basement samples showed that the surface tension at the oil-solution boundary before the exposure to temperature is 0.19 mN/m, and after exposure to temperature 91 °C – 0.21 mN/m. The experimental studies of water and surfactant compositions injection on 5 prefabricated models composed of core samples of basement rocks covering a wide range of reservoir properties showed that the injection of the oil rim with compositions based on the mixture of ethoxylated and propoxylated sulfate, α-olefin sulfonate and alkylphenol ethoxylate with a concentration of 800 ppm and an additive of polymerasulfonated polyacylate increases the oil displacement ratio.

“…The modern structure of the resource base of oil producing enterprises in the West Siberian oil and gas province has forced oil engineers to extract hard-to-recover oil reserves associated with lowpermeability reservoirs [1][2][3][4][5][6]. Involvement of unconventional reservoirs creates the need for adaptaing available technologies to specific cases and searching for economically optimal solutions [7][8][9]. The formation AV1 (1-2) is a striking example of an anisotropic, thin-layered highly-clayey reservoir, composed of sandstone of the "hazel-grouse" type, mixed-grained siltstone and clay interlayers.…”

et al. 2022

The article describes an integrated approach to the development of solutions for the effective involvement of oil in the development of a thin-layered “hazel grouse” type reservoir. The principles of justification based on facies, geological-hydrodynamic and geomechanical modeling are analyzed. In the course of the work, new core data and a petrophysical model were obtained, which made it possible to substantiate the TRIZ status of the object. A conceptual geological model was built and an assessment of geological reserves was carried out to determine the priority zones for putting wells into operation.
