The results of the AGRINI and TIERRA experiments have led us to study three general topics: collapse phenomenology, CO/sub 2/ content measurement, and gas transport in chimneys. Our results so far are fragmentary, but we have been able to come to some tentative conclusions: (1) a layer of strong material between depths of 24 and 32 m, and perhaps some relatively strong material deeper, may have caused the AGRINI crater shape. This layer was absent at the nearby LABAN and CROWDIE events. We were unable to locate the layer with a surface penetrometer or surface seismic methods, but it may be possible to measure strength vs depth in situ by examining the penetration depth of a projectile. (2) We can probably improve our knowledge of the in situ CO/sub 2/ content by calibrating a commercial carbon/oxygen logging system for NTS conditions. (3) It is possible to measure the response of the gas in a chimney to changes in atmospheric pressure. There can be significantly different gas transport in chimneys with the same pressure response, depending on the porosity and the distribution of the porosity. It is possible to perform an inexpensive experiment to study the gas transport in an existing …

Geothermal effluent from the Oregon Institute of Technology campus and Merle West Medical Center has been discharged to an open drainage ditch adjacent to the City's College Industrial Park since 1964. Over the past few years there has been increasing concern for conservation and preservation of the geothermal aquifers in Klamath Falls, Oregon. An effective way of improving the energy utilization is to cascade the approximately 130/sup 0/F effluent for heating buildings in the industrial park and disposal of the effluent in an existing injection well. An aquifer stress test was performed using the 1500 foot well in the industrial park. Based on the specific capacity, data indicate that the well is capable of accepting an injection rate of at least 700 gpm of the thermal effluent. A plume of degraded water will develop down-gradient of the well. However, the plume is expected to bypass nearby water supply wells and will have no impact on OIT and MWMC space heating wells.
