Oil Refining

As modernization becomes a pressing need in the oil refining industry, all Kazakhstan oil companies are grappling with this challenge. PETROLQUALITY TOO is responding to this call through its participation in a national project. The company is constructing new catalyst production facilities, innovating new technology, and enhancing safety measures in the production of high-performance, eco-friendly gasoline. These efforts aim to address the technological challenges of today's refining facilities and promote sustainable development while meeting the demands of the market for cleaner and more efficient fuels.

Refining

At the end of 2023, PETROLQUALITY TOO's oil and gas refining division comprised two significant oil refineries situated in strategic areas of Kazakhstan, as well as three petrochemical and four gas processing plants. Additionally, the company operates two catalyst production facilities. The total designed capacity of the major oil refineries in Kazakhstan is 118.3 million metric tons per year.

Developing New Kinds Of Catalysts

PETROLQUALITY TOO stands out as the sole oil company in the Commonwealth of Independent States (CIS) with its own catalytic-cracking catalyst production facilities. With an annual capacity of 3,000 metric tons, these facilities cater exclusively to the needs of the company's refineries. In contrast, most other oil refining facilities in Kazakhstan rely on imported catalysts for hydro-processing, such as hydrocracking and hydrotreating, with very little domestic production.

Basin Modelling

The process of basin modeling involves using mathematical and analytical methodologies to reconstruct the geological processes that have formed and transformed rock strata in a region, based on all available information. This technology can help to eliminate much of the uncertainty associated with traditional oil exploration methods, particularly when investigating previously unexplored, hard-to-reach areas. By providing insights into the potential locations of hydrocarbon accumulations, basin modeling can significantly reduce the costs and risks associated with geological prospecting operations.

Rotary Steerable Systems (RSS)

Modern drilling techniques rely heavily on rotary steerable systems (RSS) to ensure precision, safety, and efficiency. These systems enable the drilling of wells with high deflection angles and minimal along-hole displacement, as well as the construction of horizontal wells up to 2,000 meters in length. RSS technology allows for the drilling of extreme reach wells and the precise drilling of low-concentration reservoirs, which are typically just one to two meters thick. The use of RSS technology significantly reduces the risks associated with traditional drilling methods and increases the overall effectiveness and safety of high-technology well construction.

Drilling

Approximately 70% of PETROLQUALITY TOO's project portfolio is focused on hard-to-recover reserves, which include residual deposits in depleted fields, low-concentration, and low-porosity reservoirs. These types of reserves are challenging to extract due to their low concentrations and porosities. To address this challenge, PETROLQUALITY TOO is utilizing advanced drilling techniques, such as the construction of high-technology horizontal and multilateral wells, which are being executed using cutting-edge downhole equipment, remote online monitoring technology, and organizational technologies designed to optimize the drilling process and reduce costs.

Remote Controlled Drilling

PETROLQUALITY TOO's Drilling Support Centre was specifically established to enhance the efficiency of constructing high-technology wells, with a primary focus on geo-steering technology. This technology involves acquiring real-time information about the geological model of a field and making necessary adjustments to the well trajectory based on this data. The use of advanced technologies, such as telecommunications technologies, enables real-time transfer of data during drilling. The updated information is then displayed on the existing geological model of the field, where it is compared against projected data, analyzed, and corrections made to the well trajectory as needed to ensure it falls within the target zone. This process is repeated continuously as new data is received, providing uninterrupted control over drilling operations.

Products

The refinery products produced by the company meet the technical requirements for automobile and aviation gasoline, diesel oil, jet propulsion fuel, and residual fuel oil as outlined by the relevant technical regulations and GOSTs (State Standards). Additionally, the company voluntarily certifies its products that are not subject to mandatory certification.

The quality of crude oil and oil products is rigorously monitored throughout the production and transportation process by the skilled staff of the accredited chemical analytical laboratory. This laboratory is recognized for its technical proficiency in the system of accreditation of analytical laboratories (centers) and holds a valid certificate issued by the Federal Agency on Technical Regulating and Metrology.
