Application of geomechanical modeling tools to create a reservoir pressure model and reduce drilling Accidents at a oilfield in the northern part of the Yamal-Nenets Autonomous District
Authors A.E. Melkov, A.E. Glazirina, A.K. Gula, Yu.V. Ovcharenko and A.V. BochkarevSummaryThe main purpose of this work is to create a model of reservoir pressure to reduce accidents during drilling (gas occurrence, drilling fluid absorption). The field has a complex geological structure, an increased coefficient of abnormal reservoir pressure in the target formations and zones of local increase in reservoir pressure The features of the oildield are: • Growth of reservoir pressure in the Achimov strata • Presence of a zone of increased anomaly coefficient in the Ach 17-0 formation (1,7–1,9) To solve these tasks, a combination of geomechanics and geological modeling methods is used

Implementation of the technology of chromate desorption systems to optimize the position of the well relative to the contact boundaries in the development of oil rims
Authors P. Lyutoev, D. Kuznetcov, I. Nikishin, I. Platonov, M. Nukhaev and V. KabanovSummaryThis paper presents a new technology for determining the inflow profile during the development of oil rims using chromate-desorption systems, which makes it possible to solve one of the critical problems when using long horizontal and multilateral wells - optimizing the position of the well relative to the contact boundaries to prevent early water and gas breakthroughs.

Results of pilot testing of technology for monitoring gas and water breakthrough intervals using chromate desorption systems in the development of fields in the Caspian Sea
Authors A. Senkov, O. Abramenko, I. Nikishin, I. Platonov, M. Nukhaev and V. KabanovSummaryThe presented work describes a new technology for detecting gas and water breakthrough in long horizontal wells during field development in the Caspian Sea. This technology made it possible to determine the intervals of gas breakthrough using a mini-chromatograph directly in the field and did not require processing in a specialized chemical laboratory.

Unconventional reservoirs brittleness prediction for improving multistage hydraulic fracturing efficiency in horizontal wells
Authors I.Z. Karimov, B.S. Plotnikov, R.P. Volkov and D.S. IgnatovaSummaryUnconventional reservoirs, in terms of their totality of properties, are unique geological objects for which there are no generally accepted and widely tested effective methods for studying cores, interpreting well logging and seismic forecasting. For the effective development of this type of reservoir, as a rule, horizontal wells with multistage hydraulic fracturing are used, providing the maximum possible stimulated volume of rocks (SRV) and an increase in the initial and accumulated production rates. The result of hydraulic fracturing largely depends on the brittleness of the rocks and the presence of zones of natural fracturing. Prediction of these properties in the interwell spacing is a complex task that requires modern seismic processing and interpretation approaches

Performance of casing connection for horizontal oil wells
Authors A. Agishev and A. NurgalievSummaryThere is a tendency to complicate drilling techniques in the Russian Federation and in the world. It is caused by increase the number of horizontal wells and increase the length of the laterals. Casing with thread connections while run in hole operation in deviated and horizontal wells are subjected to combined loads caused by axial load, bending load, differential pressure. The most critical point of casing string is the thread connection. 50%-80% compression efficiency of connection becomes insufficient. This article describes results of FEA (finite element analysis) for API Buttress and TMK UP CWB connections and full scale test for TMK UP CWB 177.8 х 9.19 N80.
