Comprehensive Geological Consulting Service 

Geological analysis

Various surveys are conducted to understand the subsurface structures.

◇Literature review and Information collection

For the target area, various types of geological information are collected and investigated from multiple perspectives, such as the characteristics of geological structures and their development history.

◇Surface geological survey

Field surveys are conducted in the target area and surrounding regions to collect geological information, including the types of strata.

◇Geological structure analysis

Using 2D and 3D seismic survey data, subsurface geological structures?including the shape, dip, continuity, overlap of strata, as well as the presence, type, trend, and length of faults?are analyzed. A 3D geological framework (structural) model, consisting of fault planes and geological boundaries is then constructed. 

Geological model construction

Various analyses are conducted to estimate oil and gas reserves, evaluate CO? storage capacity, and to preparate base model for flow simulation.

◇Well data analysis

Well core analysis data and well logging data are analyzed to evaluate the physical properties of strata near the wells, including sand/mud identification, porosity, and water saturation.

◇Lithofacies model

Based on well data and seismic reflection patterns, sedimentary environment at the time of formation (depositional model) is estimated. Sedimentary facies analysis is then applied to evaluate horizontal and vertical lithofacies variations and continuity in each stratum.

◇Rock physical property model

By analyzing seismic attributes such as the amplitude and phase of reflected waves (attribute analysis), the physical properties and heterogeneity of strata can be estimated. As the basis for flow simulation, rock physical property model is built by applying physical information, such as porosity and permeability obtained from well data analysis and seismic attribute analysis, to lithofacies model.
