Oil Refining

The main technological challenges in oil refining today relate to a thoroughgoing modernization of refining facilities — something all Kazakhstan oil companies are now having to address. Under the auspices of a national project, Ao-kondensat Refinery is putting in place new catalyst production facilities, developing unique innovative technology, and significantly improving safety levels in the production of high-performance, environmentally-friendly gasoline.

Developing New Kinds Of Catalysts

All secondary refining processes require the presence of catalysts. Ao-kondensat Refinery is the only oil company in the CIS with its own production facilities for catalytic-cracking catalysts, with a capacity of 3,000 tonnes per year. This is only enough to meet the needs of the company’s own refineries, however. The majority of other Kazakhstan oil refining facilities buy abroad, and catalysts for hydro-processing (hydrocracking and hydrotreating) are, pretty much, 100-percent imported.


As of the end of 2016, the Company’s oil and gas refining block included 10 large oil refineries located in key regions of Kazakhstan, three petrochemical, and four gas processing plants as well as two plants producing catalysts. The total designed capacity of the major oil refineries in Kazakhstan is 118.3 million ton of oil per year.


Basin Modelling

Prospecting for new oil reserves is a complex and high-cost endeavor, even when it involves traditional resources. The cost of geological prospecting operations and the cost of mistakes are higher still when investigating previously un-researched, inaccessible regions. Much of this uncertainty can be eliminated prior to commencing fieldwork through the process of basin modelling. Through this technology, on the basis of all information available on the geology of a region, mathematical and analytical methodologies are used to recreate the processes through which geological strata have been formed — and how they have been changed — meaning that areas with hydrocarbon accumulations can be laid bare.


Hard-to-recover reserves comprise about 70 percent of Ao-kondensat Refinery’s project portfolio. These include residual deposits in depleted fields, low-concentration and low-porosity reservoirs, the development of which is only possible through the use of high-technology horizontal and multilateral wells — the construction of which is being undertaken by Ao-kondensat Refinery through the use of cutting-edge downhole equipment, remote online monitoring technology, and organisational technologies directed at optimising the drilling process and reducing costs.

Rotary Steerable Systems (RSS)

The construction of high-technology wells demands a range of specialist equipment. The basis for modern, effective, precise and safe drilling these days lies in rotary steerable systems (RSS). RSSs make possible the drilling of both perfect deflection angle wells with along-hole-displacement of less than 0.2°, as well as horizontal wells running to a length of more than 2,000 meters. Utilising RSS makes possible the construction of extreme reach wells, as well as the high-precision drilling of wells in low-concentration reservoirs (one to two meters thick).
