40 The object must be to increase reserves and production through the creation of high resolution reservoir models formed by the thorough integration of surface and subsurface data. Country-wide central databases containing information on basins, fields and reservoirs as well as increased computing power are certain to be important factors in achieving this.

1.2 Reservoir description – geology, rock and fluid interpretation Challenge commentary A challenge in Kazakhstan is to improve reservoir modelling, as it this is key to gaining a better understanding of the local petroleum systems and raising hydrocarbon recovery and operational efficiency. Sedimentology, sequence stratigraphy, structural geology, tectonics, palaeoenvironmental studies, palaeography and source rock maturation (all basin-wide disciplines) each have a role to play. Problems of inadequate reservoir modelling, especially high resolution simulations with fine grids, have reported for important fields such as Tengiz, Kashagan, Karachaganak, Uzen, Zhetybay, Kalamkas, Kenkiyak, Kumkol, Kenbay and Nurzhanov. Part of the problem of reservoir characterisation is the lack of constraints on static and dynamic reservoir models due to the limited geological, matrix and fluid information available. Substandard data interpretation (linked to the complexity of the reservoirs combined with a lack of computing power) is another issue, as is the limited ability to carry out genuinely integrated reservoir modelling (IRM). The detailed mapping and analysis of tight carbonate reservoirs is a specific challenge – understanding permeability changes occurring as the production rate falls (vital input to EOR studies) could have a huge positive impact on oil and gas production in Kazakhstan. As noted earlier, waterflooding is common in Kazakhstan, which partly accounts for the high water cuts in many fields. The challenge is therefore to improve the efficiency of waterflooding, which requires more detailed subsurface mapping and a better understanding of the water leg within the reservoir.
