Applied Geopressure Course Summary
In-depth
practice of concepts, measurements, prediction,
analysis, risk
and appraisal
New approach to definitions, causes and concepts
Course
Highlights
* Graphic plots (PD, EP-D, PPG-D)
* QC direct and indirect
measurements data
* QC petrophysical properties adequate for PP predictions
*
Simple Excel models for calculations
* Relationship between compartmentalization,
finding hydrocarbon, and risk assessment
* Application for exploration
exploitation, and drilling
Measurements
Direct PP Measurement:
Wire line tools, drill pipes,
production drill stem
Direct FP Measurement:
Limit test, leak-off test
Prediction
Ratio methods
Effective stress
model and algorithms from seismic, sonic,
resistivity, density logs
Pitfalls
and limitations
Calibration
Direct measurement Pertinent
and drilling parameters
Calculating K for fracture prediction ,
PSI
to PPG MWE, conversions
Tecnique
used for predictions
Pre-drilling
* Building the geological model
* Geopressure basin scale modeling
* Prospect scale prediction
* Proposed
well planning
While drilling
* ROP, D exponent,ECD, MW(in/out)
* LWD,MWD,
gases
* Adjust prediction parameters
After drilling
* Well logs, check-shots
