Ukrnafta begins first 3D seismic survey using wireless data logging

MOSCOW. Dec 12 (Interfax) - Ukrnafta has started Ukraine's first 3D seismic survey using wireless data logging, Ukrainian media quoted company head Sergei Koretsky as saying on social media.

The 3D seismic surveys are being carried out on an Ukrnafta property measuring 80 square km in western Ukraine, Koretsky said. More than 100 people will be involved, he said.

"The method is as follows: powerful vibrator machines operate on the surface, creating seismic waves that move underground. The waves are reflected from different rocks with the corresponding parameters. Data are collected on the surface using an extensive network of special sensors - seismometers or geophones," Koretsky said.

The sensors can also be connected to wires. This is a more common method, but not a modern one. It is much more efficient to use modern wireless systems, especially in challenging surface conditions such as rugged terrain.

The data make it possible to evaluate the internal structure of promising horizons and understand where and to what depth new wells need to be drilled.

Kotetsky also said that the company planned to begin another similar study in eastern Ukraine in 2023. It plans to use wireless data logging systems and to survey an area of around 1,000 square km in 2024.

Ukrnafta plans to start drilling nine new wells in 2023 and 30 in 2024, reports have said. It has the strategic goal of doubling oil and natural gas production by 2027, to 3 million tonnes and 2 billion cubic meters respectively. Ukrnafta plans to increase oil production 4% to 1.405 million tonnes and in 2023.

Ukrnafta is Ukraine's biggest oil producer. It has a national network of 537 filling stations, of which 456 are operating.

The biggest shareholder is Naftogaz with 50% plus one share. The Headquarters of the Supreme Commander-in-Chief ruled on November 5, 2022 to expropriate Ukrnafta shares owned by private shareholders - that stake is now controlled by the Defense Ministry.
