2-M Probe Survey +The use of off road vehicles should avoid overland travel during periods when soils are moist or wet. Backfilling of excavated probe holes.


Active Seismic Techniques +The environmental impacts of a seismic survey vary drastically and are survey-specific. Factors to consider are: terrain, land access, land usage, survey extent, seismic crew size, source (dynamite, vibroseis, etc.), accomodation for the crew, remoteness of survey location, among others.
Airborne Gravity Survey +This is a non-invasive, passive geophysical technique. The primary environmental impact is associated with fuel usage of the aircraft.
Audio-Magnetotellurics +AMT surveys is a non-invasive geophysical technique. The primary impact is due to access to the stations (4WD, ATV, etc.) and possibly line-cutting required for access to the sites in thick vegetation.


Cement Bond Log +Cement bond logs are required to evaluate the isolation and protection of usable mineral resources, ground water aquifers. This protection an isolation is generally required in federally approved wells to a depth of 2,000' in non geothermal wells. Geothermal wells are cemented behined each casing string.
Controlled Source Audio MT +CSAMT surveys are minimally invasive geophysical surveys. The fuel consumption for the transmitter and means of transport to the MT stations are the primary impacts.


Direct-Current Resistivity Survey +A DC Resistivity survey is minimally invasive and the main environmental impacts are associated with access to the survey stations. Line cutting may be required in areas of thick vegetation in order to lay out the cable.


Flow Test +There are a number of strategies for decreasing the noise that is caused from flowing a steam well, mufflers are a common method for this (Zein, et al., 2010). Depending on the chemistry of the fluid being produced from the well there may be varying stages of mitigation. If the fluid is benign to the environment and is a dry steam then it is typically released to the atmosphere. If there are high concentrations of hydrogen sulfide, carbon dioxide, ammonia, mercury, radon, or boron then some sort of scrubber or containment system should be used. However, most of the contaminants are in the liquid and are often re-injected. When the fluid produced is a water/vapor mixture it goes through a separator and the steam can be dealt with separately from the liquid.
Frequency-Domain Electromagnetic Survey +The installation of the transmitting loop and access to the receiver station locations will have the greatest surface impact and depend on the ease of access to the field area. Gasoline usage for the generator is also a consideration.


Gamma Log +Measures associated with well drilling and well logging operations.
Geophysical Techniques +Geophysical surveys are non- or minimally-invasive techniques applied to improve the understanding of the subsurface. The potential environmental impacts are related to the amount of field equipment required, the number of people needed for acquisition on the field crews, the means of access to the stations of measurement, the source of the signal for the measurement, time duration of occupancy of the measurement station, and the survey design, among others.
Ground Gravity Survey +The means of access to the gravity stations (truck, all-terrain vehicle, helicopter, boat, hiking) is the only potential environmental disturbance associated with a gravity survey. The measurement itself is non-invasive and there is negligible disturbance to the topsoil.
Ground Magnetics +The largest impact would be due to accessing the stations, by foot or vehicle or whatever means of transport is used. The measurement itself is non-invasive and there is no disturbance to the topsoil.


Magnetic Techniques +Magnetic techniques are non-invasive, passive geophysical surveys. The primary impact is due to the means of access to the stations (i.e. by foot, four-wheel drive vehicle, boat, plane, helicopter, etc.)
Magnetotelluric Techniques +MT surveys have very minimal impacts on the environment. The small holes dug for the electrodes should be refilled when the equipment is removed at the completion of the recording.<br><br> Means of access to the survey location (4WD, helicopter, ATV, etc.) are another potential impact from an MT survey.
Micro-Earthquake +See [[Passive Seismic Techniques]]<br><br> Environmental impacts associated with passive seismic monitoring are minimal.
Microgravity-Hybrid Microgravity +Microgravity provides a means to monitor environmental effects of the production of a geothermal field, namely ground subsidence. Through the application of microgravity surveys, the extent of subsidence may be monitored and corrected for in the production/reinjection strategy of the field.


Passive Seismic Techniques +The environmental impact associated with passive seismic techniques are minimal because the source for the survey is naturally occurring. The surface impact from temporary seismometer installations varies and is survey-specific.
Production Wells +When multiple wells are to be drilled sometimes direction drilling can be utilized so that more than one well can be drilled from the same drilling pad. This reduces land usage by reducing the amount of drilling pads, the amount of access roads needed, and the amount of pipeline tracks needed.


Reflection Survey +See [[Active Seismic Techniques]]
Refraction Survey +See [[Active Seismic Techniques]], [[Passive Seismic Techniques]]<br><br>


Self Potential +The small holes which are dug for the electrodes should be filled in once the measurement is complete.


Teleseismic-Seismic Monitoring +See [[Passive Seismic Techniques]]
Time-Domain Electromagnetics +TDEM is a non-invasive geophysical technique with negligible impact because direct contact with the ground surface is not necessary. The extent of vegetation may be problematic for the geophysical crews and line cutting may be required in thickly vegetated areas. Access to the stations via truck, backpacking, helicopter, etc., is also a potential environmental impact.
Tracer Testing +When conducting a tracer test it is important choose a tracer that will not cause harm to the environment especially if there is any possibility of the chemicals seeping into nearby fresh water supplies.
