Managed pressure drilling as an effective solution for wiring wells in conditions of catastrophic absorption in fractured reservoirs.

Managed pressure drilling (MPD) implies dynamic control of equivalent static and circulating densities (ESD and ECD) depending on the actual drilling conditions and objectives, gives an undeniable advantage when the use of lost circulation materials does not bring the expected effect and adversely affects the drill-in quality of the reservoir.

The drilling of the Riphean deposits of the Yurubcheno-Tokhomsky field is closely linked with catastrophic lost circulations due to the natural fracturing of the productive reservoir and low reservoir pressures. Most of the wells were not drilled to the target depth due to complications associated with lost circulation. In addition, well flow rates often did not reach planned values.

The application of MPD technology allowed to ensure successful drilling of horizontal well intervals in the fractured reservoir of Riphean deposits and significantly increased productivity of new wells.

While pilot project of MPD technology testing in 2016, 4 wells were drilled, each of which required a completely individual approach and technological flexibility. To date, the MPD technology has proven its effectiveness and made decision to continue its application in field. 


Pavel Dobrokhleb

Technical Sales Engineer


In 2006 he graduated from the Gubkin Russian State University of Oil and Gas. He began his career in 2006 with M-I SWACO from the position of drilling fluids engineer. 

Then he worked on various engineering and management positions on projects in Western Siberia.

From 2012 to 2016 he worked as an expert at the Petro-Technical Engineering Center of Schlumberger and supported key drilling projects on land.

Now, involved in the sales development of drilling fluids and Dynamic pressure management technology in Russia.

Member of industry conferences and author of a series of publications on drilling in complex conditions.

Integrated reservoir modeling (IRM) is a best practice in the upstream industry, which is applied through all life-cycle stages of oil and gas projects to help characterize subsurface reservoirs and optimize field development phases. In this respect, carbonate and clastic reservoirs are different in a range of aspects that will be highlighted. During the past 25 years, major developments in technology have proven the importance of IRM as a subsurface contributor to upstream projects. A brief history of IRM will be provided, using exploration examples from carbonates and development examples that progress up to the recent learnings about unconventional hydrocarbon trapping.

More importantly, these industry showcases will be used to introduce present-day challenges facing IRM. Despite the significant progress in modeling technologies, the root causes for the disappointing results of such studies are the limitations in software tools and workflows and the lack of integration. An outlook for the future of hydrocarbon development planning and IRM will be presented.




Jürgen Grötsch is global learning advisor for geology at Shell, where he is responsible for the design and deployment of advanced training programs. In this position, his focus areas are integration and building capabilities in decision-based subsurface modeling for multidisciplinary teams. He holds a PhD in carbonate sedimentology and has authored and coauthored numerous publications and books. Grötsch is wellknown as a keynote lecturer from international geoscience conferences and since 2009 has been a visiting lecturer at the GeoZentrum of the Universität Erlangen-Nürnberg in Germany. He is vice president of the German Geological Society.

Currently, scientific community aims efforts at solving environmental as well as health problems of the population and professionals affected natural and technological objects having geological origin.

Gradates will have the possibility to earn 2 degrees; further details will be published soon.


We invite you to SPE young professionals meeting on "The Unfulfilled Expectation of Horizontal Wells with Multi Stage fracture Completions in Conventional Reservoirs – What to do?"


In the Timano-Pechora oil and gas province, about 30% of the oil reserves are associated with carbonate sediments. About half of the deposits with reserves in carbonate reservoirs are confined to the Devonian deposits and lie at depths of two thousand and more meters. 53 such deposits were put into development.
