Abstract
The aim of the investigation is geological and geophysical data integration in a seismic-geological model of a complex heterogeneous reservoir,V13 formation, which is considered as a base for exploration works planning and successful further field appraisal.
By means of using regional data, deep geological analysis, technological projects results, unconventional approaches to geophysical data processing and interpretation taking into account peculiarities of field geology and geological modelling using geostatistical inversion the review of geology aspects V13 formation reservoir on Chona field was made and planning exploration works were reconsidered.
Two pilots of appraisal well were drilled to verify a prediction according to the final seismic-geological model. The aims of pilots were two predicted zones with good and bad reservoir quality. According to conducted cameral works and drilling results analysis it may be concluded that high detailed seismic-geological model gives a qualitative base for decision making about explorations works in conditions of complex reservoir and major explorations projects that corresponds with high economics risks.
