ABOUT UNITECH

Founded in February 2008, UNITECH is a service company specializing in petroleum engineering technologies. It positions itself as an integrated international drilling contractor with expertise spanning the entire oilfield services chain: geological studies, drilling and fracturing program design, drilling operations, mud logging, wireline logging, cementing, well completion, fracturing, well intervention, and more.

Our strategy is based on:

- Global market development

- Project management in line with international oil industry standards

- Balancing geoscience studies and oilfield operations

- Smart coordination of our resources and teams for optimal “turnkey” well services.

UNITECH is also authorized to carry out foreign trade, economic and technological management activities, and has the contractual capacity to deliver technical and engineering services nationally and internationally.

TECHNICAL EXPERTISE

CONTENT AND OBJECTIVES

Our objective is to eliminate traditional boundaries between exploration and development by providing integrated and coordinated work throughout the lifecycle of an oil and gas field, from geological research to resource assessment, development planning, and implementation.

By optimizing resource allocation and improving exploration and development efficiency, we achieve effective and sustainable development of oil and gas field.

MAIN CONTENT

In-depth Geological Studies: Application of multidisciplinary methods such as geology, geophysics, and geochemistry—to thoroughly study geological structures, sedimentary characteristics, and reservoir properties, and to build accurate geological models.

Exploration and Development Planning: Based on geological findings and development needs, we design comprehensive, rational programs that include both subsurface and surface structures.

Dynamic Monitoring and Adjustment: During oil and gas field development, we use various monitoring methods—such as dynamic reservoir surveillance and production well monitoring, to collect real-time reservoir data, enabling quick adjustments based on observed changes.

KEY TECHNOLOGIES:

2D & 3D Seismic Interpretation: Identifies the location and shape of oil and gas reservoirs.

Numerical Reservoir Simulation: simulates oil and gas reservoirs by establishing a numerical model of the reservoir, which serves as the basis for optimizing the exploitation plan.

Horizontal and Deviated Well Drilling Technologies: Increases reservoir contact area between oil and gas wells, enhancing productivity and recovery rates.

DESIGN PROCESS OVERVIEW

Geological design, Drilling design, Completion design and Fracturing design: these four stages are interdependent and follow one another logically throughout the hydrocarbon exploration and development process. Together, they guarantee efficient and safe exploitation of oil and gas resources. They are described in detail below:

These four models are closely linked. Geological design provides the basis for monitoring, drilling design implements the geological objectives, completion design ensures the production channel, and fracturing design enhances the mining effect. Together, they are involved in the whole process of oil and gas field exploration and development.

PRESENCE IN THE REPUBLIC OF THE CONGO

Since 2013, the company has been operating successfully on the BANGA CAYO oil field in the Republic of Congo. We have:

- Trained a complete exploration services team

- Performed technical services on exploration and appraisal wells

- Drilled wells during the development phase

These interventions have been highly praised by our partners for their technical quality and efficiency.

COLLABORATION WITH AFRICA OIL & GAS CORPORATION (AOGC)

As part of our drilling project with AOGC, UNITECH successfully oversaw the drilling phase. To maximize output, the wells underwent targeted hydraulic fracturing, significantly boosting production flow.

Our services covered the full operational cycle, including:

- Drilling of vertical and deviated wells

- Real-time mud logging and monitoring

- Electric logging data acquisition

- Casing cementation

- Brine filtration and treatment

- Hydraulic fracturing

- Well completion with appropriate equipment

Thanks to rigorous planning, technical mastery of operations and execution without major incident, this project enabled us to secure optimized production volumes, while meeting deadlines and QHSE standards.

COLLABORATION WITH THE CONGOLESE NATIONAL OIL COMPANY (SNPC)

As part of its strategic development, Unitech Congo has reached a new milestone with its first operational collaboration with the national oil company (SNPC) on a drilling project. This initiative marks a major step forward in our desire to work in synergy with national stakeholders in the oil sector.

Prior to this technical collaboration, UNITECH CONGO had already established strategic relationships with local institutions, laying the groundwork for sustainable partnerships. This new engagement with SNPC reflects our dedication to supporting the Congo’s energy development by promoting local expertise and strengthening industrial synergies
