Seismic examination. Test time

(Akhmetshin I.N. Gafarov R.M. Siraev I.A. )

The need to improve the quality and reliability of geological and geophysical information requires the search for new, more efficient technologies in the registration of seismic data. The article outlines the main directions of development of the exploration geophysics of Bashneftegeofizika JSC. Examples of the use of different technologies for solving complex problems facing the oil and gas industry are given.......

Hydro-pneumatic source (GPI-2) - new surface sourceof seismic vibrations excitation

(Gafarov R.M. Siraev I.A. Ekomasov S.P. Barbieri Paolo )

The authors of the work offer readers to get acquainted with pilot and production tests of a new surface seismic source GPI-2. This source is a joint product of the company «IMPULSSEIS» (Russia) and RALOT (Italy), and can compete with the currently widely used in seismic survey NOMAD-65 seismic vibrator. The first publications, which set out the principles of operation [3] and a comparison of this source with gas-dynamic source [2], occurred in 2015. «Bashneftegeofizika» JSC conducted pilot and production tests of this source at the seismic profile, as well as in the production well by vertical seismic profiling method.......

Complex seismic technologies VSP-2D, VSP-3D,VSP-CDP

(Yakupov M.T. Lenskiy V.A. Irkabaev D.R. Atnabaev R.F. )

Today, well seismic exploration plays one of the key roles in providing valuable information to oil companies not only about the deep properties of the section, but also about its geological structure. The wide range of tasks solved by well seismic exploration includes: the study of the formation and distribution of wave fields at internal points of the environment, the identification of waves of different types, the determination of their nature, the refinement of the structure of the wellbore space, the evaluation of the effective thicknesses of reservoirs, Porosity and fissuring of rocks.......

Increasing the accuracy of the estimate anisotropic parameters according to the CDP-3D in a weak azimuthal anisotropy of rocks

(Burdygina G.V. Timergazin K.K. Lenskiy V.A. Irkabaev D.R. Adiev A.Y. Arslanov D.K. Borisova M.K. Gubachev O.A. )

The paper presents a new method for study weak azimuthal anisotropy event prognosis of natural and artificial fracture characterization using AVO-attributes and velocity analysis. Results compare with offset VSP data and special well log methods date. An example of the sampling proposed method and solving actual problems in the field conditions of terrigenous section of Western Siberia.......
