Overview
• Background
• Problem / Goal
• Interim Results
Cranfield
Source of large volumes ofCO2 via pipeline
Source: Dutton and others 1993
Upper Cretaceous TuscaloosaUpper Cretaceous Tuscaloosa--Woodbine Trend Woodbine Trend ––Cranfield in Mississippi Salt BasinCranfield in Mississippi Salt Basin
Phase 2: $4.4 million Dedicated observation well + logging campaign
Gulf Coast Stacked Storage Field Test
Tuscaloosa Formation:Cranfield, MS
Natchez, MS
MS River
~3-5 MMCFD Injection ratesPhase II : ~½ Million Tons/yrPhase III : 1-1.5 Mt/yr
Problem: Many wells- How Good is Cement?
Drill through freshwaterCase and cement to seal off freshwater 2000 ft in Gulf Coast
Production casing and cement above production zone
Remaining open annulus between rock and casing=Potential leakage path for CO2 or displaced brine?
Add CO2 for Tertiary production of hydrocarbon resource

Pressure history
Most EOR– Perturbed by
extraction + injection
– Poor Pressure analog for brine reservoir
Cranfield– Discovered 1945
– Depleted, P&A 1965
– 40+ years Pressure recovery by water drive
– Similar to brine reservoir until production dominates

Phase II Interim Results– Old Wells Reasonable Integrity
• No above-zone pressure communication • ~ 40 wells - 1 mile radius OBS well
– Small leaks detectable• Small pressure changes observable • Could locate out of zone migration
– Monitoring design implication• Pressure is change - sensitive • Detectable change in 100’s ton/day @ 1Km • <5% gain/loss of contemporaneous total field rate
– RST results forthcomingOBSINJ
P&A
Could use variable responses at different OBS to triangulate on problem area.
