SPE Moscow section SPE Moscow section

On December 23, SPE Moscow section together with Gubkin University SPE Student Chapter organized a charity trip to the social rehabilitation center for minors in Suvorov.

Such trips are organized monthly. A feature of this time was the theatrical production "Bremen Town Musicians", prepared by students. It is also worth noting that each child during the previous trip wrote a letter to Santa Claus, in which he told of his desire. And at the end of the performance, the children were presented with the gifts they had conceived.

We are grateful to the members of the SPE Moscow office for assistance in implementing children's desires: Anton Ablaev, Vlada Streletskaya, Assel Salimova, Veronika Korepanova, Alena Sagon, John Gallivan, Thierry Grussaute, Ilya Novikov, Sergey Kolbikov, Kreso Kurt Butula, Vadim Salyaev, Oleg Zhdaneev; the staff of Salym Petroleum Development: Svyatoslav Kryanev, Yaroslav Gorbachev, Sergey Antipenko, Yevgeny Rodionov, as well as SPE Moscow office and Ltd LUKOIL-Engineering. Thanks to your support, every child could touch the New Year miracle.

More details about the project you can find out on the special page of the site.

We invite you to SPE young professionals meeting on "Shale volume, porosity and translation problems".

To increase the efficiency of field development, more and more wells are drilled with horizontal or high angle section at the end (HAHZ). Despite this, well logging data analysis is based on methodic and models developed using data from vertical and slant wells with relatively low inclination angle. Although it works well for vertical wells, it does not take into account geometric effects associated with high angle of drilling where wells are drilled almost parallel to formation layers. That often leads ambiguities while logging data analysis and formation evaluation in HAHZ wells compared to low angle wells. This fact does not allow using logging data from horizontal wells for geological and hydrodynamic models, which reduces its credibility.

The presentation describes uncertainties that exist when using conventional processing and interpretation techniques in horizontal wells and their causes. For demonstration purpose, the paper uses an example from real well, which has been drilled horizontally in complex environment in one of the field of Western Siberia region of Russia.

Azimuthal measurements application together with advanced modeling software packages enable more reliable estimation of well length exposed to reservoir, spatial position of its boundaries and essential reservoir properties, such as porosity and saturation. As a result, the geological model may be refined locally.

Colleagues, we wish you a Merry Christmas and a Happy New Year!

The past year turned out to be important for the events - 25 years of the Moscow section, 10 years for the Moscow office and 60 years for the World Community were celebrated!

In the coming year, we will continue to improve and implement new ideas!
