Halliburton has successfully completed a series of offshore wireline operations for Croatia’s INA Group in the Adriatic Sea, demonstrating both technical strength and operational efficiency.
The project involved logging activities across four wells, where the Wireline team carried out 17 combined runs without any health, safety, or environmental incidents, while also maintaining zero non productive time.
Over the course of more than 272 hours of continuous operations, the team ensured that all personnel and equipment were securely managed on site. By keeping closely aligned with INA’s project schedule, Halliburton delivered the work within the agreed timeline, allowing the client to assess well performance and make informed operational decisions in real time.
A key element of the project was the development of an integrated workflow that combined measurement and analysis. This approach played an important role in identifying promising production opportunities as well as uncovering new hydrocarbon zones offshore Croatia. The team worked closely with INA’s subsurface specialists, offering real time support through formation testing and detailed petrophysical interpretation.
To better understand thin geological layers, Halliburton deployed its Xtended range water based mud imager. This technology enabled accurate identification of sandstone intervals and helped determine net pay zones. In addition, enhanced vertical resolution techniques were used to capture density and neutron porosity data, improving the analysis of shaly sand formations and refining estimates of porosity and gas saturation.
Further insights were gained through the use of the Reservoir Description Tool, which measured fluid density, capacitance, and resistivity during pump out operations. These measurements confirmed the presence of productive gas zones. The team also applied magnetic resonance technology to distinguish between moveable and bound hydrocarbons, providing a clearer picture of reservoir potential.
Through a combination of innovation, precision, and collaboration, Halliburton delivered a seamless operation that supported INA in unlocking valuable subsurface insights.
