Answer:
I have extensive experience interpreting 2D and 3D seismic data, identifying structural traps, fault systems, and stratigraphic features. I have used seismic attributes to delineate reservoir sweet spots and predict fluid contacts. My work involved defining drilling targets.

Question 5

How do you integrate well log data with seismic interpretations?
Answer:
I integrate well log data by generating synthetic seismograms and correlating them with seismic sections to calibrate interpretations. I also use petrophysical analysis from logs to understand reservoir properties like porosity and saturation. This ensures a comprehensive subsurface picture.

Question 6

Describe a challenging geological problem you faced and how you solved it.
Answer:
During a prospect evaluation, we encountered conflicting seismic and well data in a structurally complex area. I re-evaluated all available data, performed detailed structural restoration, and proposed an alternative geological model. This led to a successful well placement.

Question 7

What is your familiarity with geological modeling software?
Answer:
I am highly proficient in Petrel, having used it for building 3D geological models, fault interpretation, horizon mapping, and property modeling. I have also used it for volume calculations and uncertainty analysis. This allowed me to create robust reservoir representations.

Question 8

How do you assess reservoir quality from core samples?
Answer:
From core samples, I analyze lithology, sedimentary structures, and diagenetic features to understand depositional environments and reservoir architecture. I integrate core analysis data like porosity and permeability measurements with wireline logs. This provides a detailed understanding of reservoir rock properties.

Question 9
