SPE Workshop: Horizontal Wells Survey Results

Posted on 04 December 2020

The third SPE Workshop: Horizontal Wells Survey was held online on 25-26 November 2020.

More than 40 delegates from leading operating companies, including Gazprom Neft, LUKOIL and Rosneft, large service companies and scientific institutes took part in the workshop.

Program committee noted the high level of the technical programme, which is improving from year to year. The online format did not become an obstacle for active discussions: participants discussed not only the presentations but also the application of survey results during the round table. In addition, the remote format made it possible to present a joint report by Sinopec Group and GeoSplit about tracer studies in horizontal gas wells in China, made by a Chinese expert.

The programme committee and moderators selected the best presentations:

  1. Danila Gulyaev, Sofoil. Identification of the working length of a horizontal wellbore and evaluation of the quantitative interference based on the analysis of wells performance history in an offshore field.
  2. Rashid Yarullin, Rim Valiullin, Airat Yarullin, Geotech/Bashkir State University. Efficiency and informativeness of the spectral acoustic noise measurement method for conducting geophysical studies in active horizontal wells.
  3. Mikhail Kremenetsky, A.Sharipov, Gazpromneft STC. Informativeness and problems of thermometry with distributed fibre-based gauges in horizontal wells
  4. Nikita Morozovsky, Rosneft. Integration of field researches for optimization of horizontal well stock performance: experience and examples of implementation.

The workshop evolves with the industry demands and trends. There were two brand new topics raised this year in addition to the traditional ones: geomechanics and machine learning. Technical programme has been well received by industry experts.

Andrey Ipatov, Gazpromneft STC, noted that almost all presentations at the workshop included analysis and interpretation.

"It means we are making progress and moving away from the first stage, when companies focused on the wells survey organization process and instrumental survey database set up. This trend is very encouraging". Andrey Ipatov, Gazpromneft STC

"Future belongs to permanent systems. Number of wells with permanent sensors is already growing, and a question of the received data processing is raised". Fedor Zavalin, NOVATEK STC

"The industry needs common standards well performance analysis with permanent sensors. The other question is integration of the results with other research methods". Nikita Morozovsky, Rosneft

"Field development by horizontal wells with multi-stage hydraulic fracturing becomes more important every year. Requirements for the efficiency and accuracy of physical data recording are increasing, the range of measurements is expanding, and new ways of obtaining measurements are emerging. In this regard, there is a growing need to improve methods for analyzing large amounts of data, to increase speed of processing and making operational decisions. In 2022 we look forward to even more case studies demonstrating a successful breakthrough to the future we look ahead". Sergey Abramochkin, Tachyus
