This paper presents three brief case histories from a three year study comparing electro-convulsive therapy (ECT) with acupuncture treatment in functional psychoses. Acupuncture effects were augmented by the simultaneous, non-painful electrical stimulation of eight acupuncture needles. The resulting treatment is called Acupuncture Electric Stimulation Therapy (Acu-EST). Each patient was utilized as her own control, treating exacerbations of depression alternately with ECT and Acu-EST, Acu-EST was found to be a panacea and did not enable the discountinuation of antidepressant and neuroleptic medication. Individual Acu-EST treatments were often less effective than individual ECT treatments. However, series of Acu-EST did assist in producing significant remissions in depressive symptomatology. Because it did not produce the temporary disabling memory defects which occurred with ECT, Acu-EST was more easily adaptable to outpatient treatment.

A hydrothermal doublet system was drilled in a fault-related granitic reservoir in Cornwall. It targets the Porthtowan Fault Zone (PTF), which transects the Carnmenellis granite, one of the onshore plutons of the Cornubian Batholith in SW England. At 5058 m depth (TVD, 5275 m MD) up to 190 °C were reached in the dedicated production well. The injection well is aligned vertically above the production well and reaches a depth of 2393 m MD. As part of the design process for potential chemical stimulation of the open-hole sections of the hydrothermal doublet, lab-scale acidification experiments were performed on outcrop analogue samples from the Cornubian Batholith, which include mineralised veins. The experimental setup comprised autoclave experiments on sample powder and plugs, and core flooding tests on sample plugs to investigate to what degree the permeability of natural and artificial (saw-cut) fractures can be enhanced. All samples were petrologically and petrophysically analysed before and after the acidification experiments to track all changes resulting from the acidification. Based on the comparison of the mineralogical composition of the OAS samples with the drill cuttings from the production well, the results can be transferred to the hydrothermally altered zones around the faults and fractures of the PTF. Core Flooding Tests and Autoclave Experiments result in permeability enhancement factors of 4 to >20 and 0.1 to 40, respectively. Mineral reprecipitation can be avoided in the stimulated samples by sufficient post-flushing.
