Meetings

This presentation will show many aspects of hydraulic fracturing practice in TNK-BP. An overview of the main achievements of different fracturing methods will be provided.

Due to this presentation you may learn the basic practices, problems solutions in various stages of hydraulic fracturing, to consult the relevant field data, analysis of different situations, to discuss methods of solving technological problems in the field development practice.

Many exploration and production companies impose a risk threshold on major capital projects (one common such hurdle is a maximum acceptable probability of negative NPV). Projects which fail to meet the threshold are not usually rejected outright; rather, the project team is instructed to gather more information and perform more analyses, so as to reduce the range of economic uncertainty associated with the project.

This presentation is devoted to practical aspects of development and application of Foam Assisted Lift (FAL) technology.

After short discussion on liquid loading phenomena, considerable attention is paid to gathering and analysis of information during candidate-well selection for FAL program, practical issues of treatment type selection, to optimization and monitoring of the treatment performance and advantages of FAL as compare with different AL technologies.

Lately, the selection and research of the isolated core from argillaceous-siliceous deposits of the Bazhenov formation allowed receiving new information about reservoirs of these strata. New information contradicts the earlier existing opinion, about clay reservoirs of the Bazhenov formation. On the example of a several fields, located on the different flanks of the Frolovsky megahollow in Western Siberia, it was proven that generally, the reservoirs of the Bazhenov formation are dated for radiolarian layers, in various degree siliceous or carbonaceous.

Abstract:

Development of Far North oil and gas field is growing in Russia especially in Yamal region. Cementing of top sections always been a challenge due to Permafrost formation and shallow gas. Conventional cementing systems cannot meet requirements to provide good zonal isolation due to low temperature. Special systems were developed to provide short thickening time and quick compressive strength development.

When designing a well, the main goal is to have the simplest possible completion, while being able to get the greatest amount of information and concomitantly to achieve the most encompassing well control. Simplicity and ability to get information and control are at first antagonistic drives, not to mention the duality of cost-benefit. One way to solve this paradigm is obviously to face the risk and increase the number of field cases.

In the last decade, our understanding of shale reservoirs has progressed significantly. It is now agreed that a major factor for the productivity of shale reservoirs is the existence of a pervasive reservoir fracture network around the well. Accordingly, a common practice is to use hydraulically fractured horizontal wells to improve the connection with the reservoir fractures.
