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 modeling. 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 Suzun 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 Suzun through the use of cutting-edge downhole equipment, remote online monitoring technology, and organisational technologies directed at optimising the drilling process and reducing costs.
