Pre-Drilling (Modeling):

• Building the geological blocks:  sequence stratigraphy, depositional style, structural evolution, faults and salt timing etc.
• QC and apply seismic velocities for predicting PP / assess AVO
• QC and apply petrophysical data of offset wells for calibrating  PP / FP
• Establish PP / FP parameters, exponents, and calculate NCT
• Build the prediction model and calculate PP-FP profiles in psi and ppg of proposed location
• Pre-Drilling seals vs. reservoirs compartmentalization evaluation (when possible)
• Establish casing and mud programs and expected drilling challenges along the bore hole trajectory

During-Drilling (Calibration):

• MWD, mud logs, measurements, drilling events

• Calibration of the pre-drilling Geopressure Model  (new approach)

• Ahead of the drilling bit prediction

Post-Drilling (Appraisal):

• Success or failure assessments
• Appraisal of vertical and lateral seals and the exploration potentials in the offset structural segments
• Calculating of sealing and hydrocarbon retention capacities
• Trapped hydrocarbon limits and volume

"Everyone felt that, at present, there were just some 'cookbook' formulas for addressing velocity that sometimes fit and sometimes do not"
