Well Logging

Control over the development of oil and gas fields.

Implementation of geophysical service work on GIS monitoring of development in oil and gas wells, including inclined and horizontal ones.

The work is carried out using modern equipment developed and manufactured by Velco specialists: logging hoists and Velco-Geo computerized logging loggers

The geophysical equipment used ensures the performance of work in accordance with the requirements of the "Technical Instructions for conducting geophysical research and cable work in oil and gas wells" M., 2001.

Geophysical studies of hydrogeological, engineering-geological, coal and ore wells. Engineering geophysics.

Geophysical surveys of wells are carried out with modern computerized well logging stations SKG-1 and digital downhole tools developed and manufactured by Velko. The studies are carried out by qualified geophysicists using modern software.

A set of methods for studying hydrogeological and engineering-geological wells:

• standard electric logging KS-PS
• GC radioactive logging
• density gamma - gamma logging (GGK P)
• neutron-neutron logging (NNCt)
• neutron gamma ray logging
• cavernometry
• resistivimetry
• thermometry
• flow measurement
• inclinometry
• clutch locator

Digital downhole equipment provides the ability to simultaneously register several parameters: electrical resistivity by gradient and potential probes and PS, electrical resistivity and natural gamma activity, natural gamma activity (GC) - thermometry - resistivimetry, etc.

A wide range of problems is being solved: from lithological partitioning of a section, allocation of aquifers to determining the filtration properties of formations (according to resistivity and flow measurements), determining porosity.

Video logging is carried out with optical visualization of data on a computer monitor with recording on electronic media. The equipment provides a frontal view (top-down) and a side view of the walls of the well (studying the technical condition of the column and filters) with a rotating video camera.

Geophysical exploration of ore wells.

The complex of methods includes:

Geophysical studies of coal wells.

The complex of methods includes:

• standard electric logging KS-PS,
• gamma logging (integrated),
• selective gamma-gamma-ray logging (GGK S),
• density gamma-gamma-ray logging (GGK P),
• neutron-neutron logging (NNCt),
• acoustic logging
• cavernometry
• resistivimetry
• thermometry
• inclinometry.

The company's specialists provide assistance in writing reports on the results of geophysical surveys, including the preparation of geological materials for submission to the GCZ Rosnedra.
