More details about the topic

 

In order to increase hydrocarbon reserves and to boost its recovery at least two ways are possible – new fields discovering or investments of new effective techniques for current fields study and reserves development. The last approach is both economically and technologically reasonable. 

Analysis of the current situation in the field of laboratory studies of rock samples and in the petrophysical modeling enables to highlight the following.

Firstly, standard core lithological description is often not sufficient to characterize the reservoir properties of the rock. Belonging of the rocks to the sandstone lithology does not guarantee the presence of connected pore system since sandstone can be formed in different depositional environments.

Secondly, when building model for single stratigraphic level (formation or formations group), petrophysical modeling principles are based on the generalized approach. This approach is designed for the relatively homogeneous and isotropic deposits. The analysis shows that the use of a generalized approach to the heterogeneous intervals may lead to missing thickness of the productive intervals up to 4% in total, whereupon error in water saturation calculation can reach 35%, in turn it leads to additional errors in the determination of the oil recovery factor up to 15% from the real values.

Thirdly, the reservoir stimulation process (heating, hot water injection , etc.) for production enhancement is carried out based on the average values of the reservoir properties. If not take in to account information about the structural features of the pore space of rocks may result in additional time and costs in the development of deposits. The simple evidence of such situation is a crossplot "permeability vs porosity", when the same reservoir, its permeability can be varied over a wide range (2-3 decades).

LLC "Gazpromneft science & technology center" has wide experience in petrophysical modeling of reservoir properties involving core facies analysis. As a result of those analyses, the reservoirs cut-off values were clarified, and the calculation algorithms for petrophysical properties were fine tuned.

Fine tuning of log data interpretation methodology by applying structural variation of reservoir pore space provides:

• Reservoir permeability typing;

• Residual hydrocarbons identification within the reservoir;

• Choosing of proper field development strategy.
