SPE Workshop
Hard-to-Recover Reserves

24-26 April 2018
Minsk, Belarus | DoubleTree by Hilton Hotel Minsk

Session 1. Formation and Localization of Hard-to-Recover Reserves

This section will cover three areas – regional geology, basin modelling and hard-to-recover reserves localization.  Determining regional geological structure features the set of tasks are being performed, such as studying regional paleo-geographic and paleotectonic features, building geodynamic models of structural and formational complex and model of regional geological development, development of structural and formational zonation.

Basin modelling as a modern instrument of hydrocarbon system analysis helps to get the most from reserves difficult to recover of complex structure.

Localization of reserves and hydrocarbon potential assessment of paleobasin in the session will cover tasks specific to shale deposits: oil-and-gas source – the possibility of formation and localization, geological resources assessment, cost-effective recovery methods of geologic play development etc.

We invite you to share your experience, both successful and revealing any problem to discuss with the experts onsite.

Session 2. Current Methods of Hard-to-Recover Reserves Prospecting and Estimation   

Against conventional oil and gas reserves depletion, operating companies are focusing on appraisal and estimation of reserves which used to be considered as loss-making, and have low reservoir quality and low saturation, complex geology and requires state-of-the-art and often very expensive technologies. Therefore, the most important target of world petroleum community appears to be developing an optimum set of methods to prospect and estimate reserves in various geographical and geological conditions,    allowing to have reliable information at minimum expense.

The session will be devoted to efficiency and application features of hard to recover reserves prospecting and estimation methods under the following areas:

  • Seismic for sweet-spots. Accomplishments and lessons learned;
  • Geochemistry as one of potentially effective hard-to-recover reserves prospecting method;
  • Сore sampling, treatment and measured values;
  • Well production logging – best practices and trends;
  • Innovative forecast methods of local oil bearing capacity based on surface testing and deep investigations.


In addition to the main technical sessions, the Programme Committee is interested in the organizing of Poster Session. Posters will give the participants additional opportunities to share their ideas and technologies. To get more information and to participate in Poster Session you can contact Antonina Kozmina.

Session 3. Effective Technologies for Drilling, Development and Stimulation

The well construction in fields with hard-to-recover reserves is inherent in effective wellbore placement and extended horizontal shaft targeting in the heterogeneous tight reservoir. Extended multihole horizontal drilling has become standard practice, «hydraulic fracturing as well recovery» has been replaced by «hydraulic fracturing required to start a well». Drilling, exploration and stimulation technologies progress, and only as a result new hydrocarbon reserves marked as noncommercial, are brought into development. Well stimulation for hard-to-recover reserves requires extra engineering solutions. Brownfields need a rethink of technological approaches to extract remaining reserves and hard-to-recover reserves.

We are going to discuss the following areas in the session:

  • Modern approaches in drilling for hard-to-recover reserves, extended horizontal shaft construction in the unconventional reservoir, multilateral wells;
  • Real-time geosteering, extended horizontal shaft drilling using Rotary Steerable System, proper horizontal wellbore placement factors;
  • Multistage hydraulic fracturing wells – completion and stimulation, efficiency and operation speed increase. New methods and technologies for unconventional reservoirs;
  • Existing wells stimulation – new approaches for brownfields. Refracturing efficiency and feasibility for hard to recover reserves, well assembly and fail-safe operation technologies.

Session 4. Unconventional/Tight Reservoirs Development

In the session, we will consider all technological aspects of the integrated design of development and production unconventional hydrocarbon, significant problems operating companies face in different regions, new trends of science and technologies.

Experts will present their vision of tight reservoir development in view of existing and potential solutions and challenges.

The session will cover the following topics:

  • Flow characteristics study of unconventional/ tight reservoirs;
  • Pilot project design;
  • Drainage area identification and optimum development parameters;
  • Production forecast due to geological and geomechanical aspects of the reservoir;
  • Natural fracture impact on drainage area formation and hydraulic fracturing of different design success;
  • Well logging and flow testing interpretation – methodic aspects for stimulated volume;
  • The well production analysis and its variation reason – equipment selection and operational mode;
  • The flow of fluid in a well;
  • Composition and PVT fluid properties, its impact on production;
  • Oil recovery methods potential assessment;
  • Integrated modelling;
  • Methodic aspects of recoverable resources definition
