Ukrnafta specialists have developed and implemented their own software suite, WellWorkoverSupervisor, for planning and managing well workovers.
“This solution was developed in-house based on the practical experience of the company’s specialists, taking into account international best practices,” the company announced on Tuesday.
Ukrnafta explained that well workovers are one of the most complex production processes, as working with equipment at depths of several thousand meters requires precise engineering calculations, high-quality preparation, and strict adherence to safety requirements.
Previously, the company did not have a single standardized software tool for such calculations. Some of the work was performed manually or using outdated software, which took more time and increased the risk of errors.
However, engineers from the Well Repair Supervision Division of the Production and Technology Department have developed their own software product that meets the company’s actual production needs.
“Digital transformation is not just about purchasing off-the-shelf IT solutions. It also involves developing our own engineering expertise and creating tools that directly improve production efficiency,” said Bogdan Kukura, Chairman of the Board of JSC “Ukrnafta.”
According to him, the use of WellWorkoverSupervisor has already made it possible to reduce the time required to prepare work plans, minimize the risk of errors in calculations, and improve production safety.
WellWorkoverSupervisor includes over 30 specialized modules and allows users to automate key technical calculations, create graphs and engineering diagrams, generate ready-to-use PDF reports, and utilize a built-in reference guide for pipes, threaded connections, and equipment.
In terms of functionality, the software suite is on par with expensive foreign counterparts, Ukrnafta added.

The Kametstal plant, part of Metinvest’s mining and metallurgical group and located at the Dniprovsky Metallurgical Plant (Kamenskoye, Dnipropetrovsk Oblast), has carried out a major overhaul of part of its pulverized coal injection (PCI) equipment in the blast furnace to reduce energy consumption.
According to the company, the efficiency of blast furnace production at Kametstal is inextricably linked to the reliability of the PCF injection technology; therefore, to ensure the stable operation of this equipment, grinding circuit No. 2—a key stage of this year’s modernization of the PCF complex—has been overhauled.
As specified, PFC is an energy resource that serves as a highly efficient carbon component and makes it possible to drastically reduce natural gas consumption or completely eliminate it from the smelting process. Injection of PVP also makes it possible to reduce the consumption of coke and coke equivalent of standard fuel and contributes to increased productivity of blast furnaces.
The PVP section supplies fuel not only to blast furnace production but also to the rotary kilns of the lime-burning shop.
Kametstal was established on the basis of PJSC Dniprovsky Coke Chemical Plant (DKHP) and PJSC Dniprovsky Metallurgical Plant (DMP). It is part of the Metinvest Group.
Metinvest is a vertically integrated group of mining and metallurgical enterprises. Its enterprises are located in Ukraine—in the Donetsk, Luhansk, Zaporizhzhia, and Dnipropetrovsk regions—as well as in European countries. The holding’s main shareholders are the SCM Group (71.24%) and Smart Holding (23.76%). Metinvest Holding LLC is the management company of the Metinvest Group.
Starting May 1, Ukrzaliznytsia (UZ) is fully implementing an automated service for scheduling freight car repairs with the aim of minimizing human error, improving the efficiency of rolling stock utilization, and reducing downtime.
“In fact, from now on, the entire process—from repair planning to final billing—will take place online within a single system,” UZ notes on Facebook.
The company explains that to have cars repaired at its facilities, three online stages must be completed, including the already operational planning and contract stage, during which information on available capacity, rates, and terms is published in the system, and the car owner submits an electronic application with an annual repair plan. After that, the parties conclude a contract online using a qualified electronic signature (QES).
In the second stage (application submission and repair), which began on May 1, the client makes an advance payment, submits the application independently by selecting the production unit to receive the service, after which the railcars are sent for repair. All work is performed according to an automatically generated queue.
In the third stage (completion and billing), after repairs, the system generates certificates of completion and necessary documents with a QES. These become available in the customer’s electronic account, after which final billing takes place.
“Thus, customers receive a fully digital process without paper documents: the contract, requests, repair tracking, and all settlements—all in one service. A personal account is automatically created for each customer, and contracts can be renewed online,” the post concludes.
On Wednesday, after 12:00 p.m., Ukraine resumed oil transit via the Druzhba pipeline, according to a source close to the Ukrainian government who spoke to the online portal “Energoreforma.”
“At 12:35 p.m., oil transit was launched. Pumping has begun,” said the source speaking to “Energoreforma.”
He has not yet specified the volume of the transit.
As reported with reference to Slovak Economy Minister Denisa Saková, the resumption of supplies via the Druzhba pipeline to that country is expected on Thursday morning.
Hungary and Slovakia have not received Russian oil via the Druzhba pipeline since January 27 of this year due to damage to the pipeline caused by Russian shelling. Earlier, Hungarian Prime Minister Viktor Orbán stated that he would not lift his veto on the €90 billion EU loan for Ukraine until oil supplies are restored.
Péter Magyar, leader of the Tisza Party, which won the elections in Hungary, called on Ukrainian President Volodymyr Zelenskyy to ensure the Druzhba pipeline is restored as soon as possible.
The day before, the Kremlin stated that Russia is technically ready to resume transit through the Druzhba pipeline to Hungary.
Hungarian MOL announced on Wednesday, April 22, that the state-owned JSC “Ukrtransnafta,” responsible for operating the Ukrainian section of the Druzhba pipeline, had officially notified it of the completion of repair work on the Druzhba pipeline, as well as the termination of the force majeure circumstances that had been in effect since January 27, 2026.
JSC “Ukrnafta” has implemented a corporate system for maintenance and repair (M&R) management and has begun putting it into practical use, according to a press release issued by the company on Tuesday.
“The goal is to create a unified electronic system for managing production assets: from equipment inventory to the analysis of maintenance and repair costs,” the press release stated.
The company explained that this essentially involves creating a “digital twin,” which allows for more accurate work planning, cost forecasting, and more efficient use of resources.
Since February 2026, the system has been in pilot operation at Ukrnafta’s regional divisions.
The project is being implemented based on the EAM (Enterprise Asset Management) approach. It encompasses 16 modules and 39 end-to-end business processes at Levels 1 and 2, ensuring management of the full lifecycle of production assets.
According to Ukrnafta, one of the project’s key priorities is the creation of a unified equipment database. Approximately 47,000 fixed assets have already been identified, of which 39,000 (over 80%) have been uploaded to the system. Approximately 8,000 repair objects have been created, over 150 types of equipment (more than 4,800 models) have been standardized, and more than 7,000 units of technical documentation have been uploaded.
A digital passport is created for each object, containing a complete history of repairs, defects, downtime, and relocations.
In addition, a maintenance and repair (M&R) standards database has been created: over 10,000 process charts contain per-operation labor costs, standards, a list of tools, and qualification requirements. All resources are integrated with the ERP system, enabling the automation of procurement requests and order generation.
The request management process (BPMN 2.0) has also been standardized—from defect recording to analysis of completed work and transfer of costs to the ERP. Approximately 500 typical defects have already been defined for the analysis of technical failures.
The system is integrated with the ERP, ensuring transparent financial accounting of repairs and cost control at every stage.
“We are systematically transitioning to a digital model of production asset management. This is not a standalone IT project, but a shift in the approach to production management. The system enables control at all stages—from equipment condition and work planning to costs and performance results,” said Ukrnafta CEO Bohdan Kukura, as quoted by the press service.
According to him, this results in increased process transparency, execution discipline, and the quality of management decisions.
In turn, as explained by Oleg Deberyna, head of the maintenance and repair system implementation department, Ukrnafta is effectively creating a unified digital asset management system that enables real-time monitoring of equipment status, work planning, and control over resources and costs.
“It is important that the system covers the entire cycle—from defect recording to failure root cause analysis and management decision-making. This significantly improves the efficiency and manageability of production processes,” he added.
As the company summarized, the implementation of the M&R system represents a shift in the approach to asset management: unified rules for working with equipment, standardization of processes, enhanced data management, and improved production reliability and safety.
The next stage is scaling the system to all of the company’s structural units, including internal services. Implementation will proceed in phases until mid-2027.
