Petrophysics

Petrophysical studies are one of the primary sources of information about the availability and distribution of hydrocarbons in the reservoir. These studies involve an integrated survey of geological and geophysical properties of the rock near the wellbore using special wireline logging tools for measuring natural and artificial physical fields. Such tools run in hole by the cable or drillpipes, or may be installed directly on the drill string.

Acquired data is used to determine the lithology, identify the intervals of various rocks and then allocate producing reservoirs and evaluate their flow properties, including porosity, permeability, oil saturation, etc.

STC specialists have the task of selecting the optimal range of well survey program, interpret the results, conduct analytical research of dependencies between various physical properties of the rock, and develop models of producing formation response (petrophysical modeling). Petrophysical parameters, along with seismic/production and other data, form the basis for subsequent geological modeling of oil and gas fields and evaluation of hydrocarbon reserves in the reservoir, as well as to identify the predominant trends in spatial distribution of properties.

Looking for continuous increase in field development efficiency, STC specialists work on making petrophysical analysis to be more informative. This involves both the use of innovative techniques of geophysical well logging and related logging processes, and optimization of standard formation studies. Introduction of new technologies helps to develop more accurate geological models that are later used for selecting specific process solutions in reservoir engineering.
