Lessons Learned from Waste Water Disposal in Kansas: Applications for CO2 Geological Storage

Yevhen Holubnyak, Lynn Watney, and Tandis S. Bidgoli


Outline• Current state of seismicity and waste disposal in

Sothern Kansas• Waste disposal targets? Arbuckle group

properties• Modeling and observations



Seismic and Waste Disposal Trends in Sothern Kansas

Slight reduction in seismic activity following state restriction order on injection volumes and other factors

Well count


Earthquakes and geology in

south-central KS and north-central OK

• Brine injection in Oklahoma in 2014 was ~2 billion barrels

• Earthquakes are larger and more numerous in Oklahoma.

What Do We Know About Arbuckle?• ~1000 ft thick carbonate• ~5-7% porosity• ~200 mD permeability• Under-pressured (location dependent)• Basement conditions? Faults?• Waste disposal target for over 30 years


Common Analogs• What is the capacity?• Empty Volume = 37M ft3 =

6.6M bbls• If Ø = 5-7 %• VolumeØ = ~450K bbls• If efficiency = 50 %• Volumee = ~ 225K bbls• High volume wells used to

deliver up to 30K bbls/day• Therefore

It would take up to 7-15 days to fill up this volume (without considering existing water)

• It would take 111-222 “ES units” to accommodate 50M bbls injected in 2014

• Translates into 3.9-7.8M ft2

• Harper Co. Area = 22.4B ft2

• “Plunging” system?
