Burial history model for a well of Anadarko basin in 1D extraction (upper image) from the 4D petroleum system model and Woodford shale transformation ratio from Anadarko basin (Higley et al., 2013)
Petroleum Systems Analysis
Petroleum Systems Analysis
1-D, 2D, & 3-D burial history & thermal maturity modeling
Integrate structural and geophysical attributes to model petroleum migration and accumulation by incorporating pore pressure and lithologic data
Better understanding of generation, expulsion, migration & retention in petroleum systems
Optimizing appraisal and exploitation of conventional & unconventional petroleum resources
We use Zetaware software: Genesis, Trinity, and Kinex and PetroMod Software
Gas-to-Oil ratio (GOR) modleing based on the geochemistry and PVT calibration from Anadarko Basin, Oklahoma (Rahman et al., 2017: URTeC 2688342)
Petroleum Phase and Source of HC
Petroleum Phase and Source of HC
Interpret mud/produce gases compositional and isotope data to predict reservoir fluids
Predict API gravity, hydrocarbon phases, GOR, and BTU through geochemical analysis of source rocks, oil and gas.
Origin of hydrocarbon (oil and gas)
Assessments of sources through rock-eval analysis, organic petrology, source rocks kinetics
GC fingerprinting (GC-FID, GC-GC) and saturates and aromatics biomarkers (GCMS, GCMSMS) from oil/extracts and stable isotopes
Step-1: Initial fingerprints are key to understand the effectiveness of drainage volume/production
Step-2: Allocate the produced oil/gas through application of machine learning (ML) techniques on the geochemical fingerprints collected during drilling and time-series produced fluids (water, oil and gas)
Production Allocation
Production Allocation
The reservoir quality of rock and fluid can vary greatly among the stacked layers
Production allocation to the sub-members of the target reservoir(s) is crucial to a successful horizontal development strategy
Initial fingerprints are key to the effectiveness of production/drainage volume understanding
Initial mixing ratios can indicate effectiveness of frac stages/well completion
Mixing from upper and lower units changes over time and is reflected by changes in produced oil chromatography/fingerprint
