Afghanistan: Narcotics and U.S. Policy (open access)

Afghanistan: Narcotics and U.S. Policy

This report provides current statistical information, profiles the Afghanistan narcotics trade's participants, explores linkages between narcotics, insecurity, and corruption, and reviews U.S. and international policy responses since late 2001. The report also considers ongoing policy debates regarding the counternarcotics role of coalition military forces, poppy eradication, alternative livelihoods, and funding issues for Congress.

Continuous active-source seismic monitoring of CO2 injection in abrine aquifer (open access)

Continuous active-source seismic monitoring of CO2 injection in abrine aquifer

Continuous crosswell seismic monitoring of a small-scale CO2injection was accomplished with the development of a noveltubing-deployed piezoelectric borehole source. This piezotube source wasdeployed on the CO2 injection tubing, near the top of the saline aquiferreservoir at 1657-m depth, and allowed acquisition of crosswellrecordings at 15-minute intervals during the multiday injection. Thechange in traveltime recorded at various depths in a nearby observationwell allowed hour-by-hour monitoring of the growing CO2 plume via theinduced seismic velocity change. Traveltime changes of 0.2 to 1.0 ms ( upto 8 percent ) were observed, with no change seen at control sensorsplaced above the reservoir. The traveltime measurements indicate that theCO2 plume reached the top of the reservoir sand before reaching theobservation well, where regular fluid sampling was occuring during theinjection, thus providing information about the in situ buoyancy ofCO2.
