The Geysers Geothermal Field The Geysers Database at RISSC/AMRA

Aldo, Zollo & Ma=eo Picozzi



Figures: Majer & Peterson 2007 (Int. J. Rock Mech. Mining Sci.) and Beall et al. 2010 (GRC Trans.)

Field-wide seismicity (M>1.2) and industrial activity 1965–2010

Vapor-dominated geothermal field in Northern California (reservoir at 1.1–3.3 km depth).

Steam production since the 1960s, and today world's largest field (inst. capacity 1584 MWe),

operated by Calpine and NCPA.

Seismicity induced in upper 5 km of the crust, in the reservoir below producing wells and near

injection wells; largest event Mw 4.6 (2006-10-20).

Reservoir sketch

and induced seismicity in 2009




Berkeley-Geysers (BG) network of 31 3-C surface stations (red):

Instrumentation: SM-6, 14 Hz geophones until fall 2009, now Oyo GS-11D 4.5 Hz sensors.

Acquisition: 2 ms sampling, trigger mode (often 80 s traces with 40 s pre-trigger time).




The Geysers Data at RISSC

Events and BG stations (red) with SAC files available in

the waveform database at RISSC (Nov. 2011)

Magnitude distribution



Data providers: NCEDC (LBNL, Calpine): waveforms, bulletins, station/instrument info

USGS: Quaternary fault database

ISOR: DVD of scanned reports and tables (1969 to early 2009).

Database preparation:

Download of event catalogs, station coordinates, phase readings from NCEDC

Preparation of breq_fast/netDC requests for NCEDC, mostly based on station trigger times

Retrieval of SEED volumes, conversion to SAC, and association of triggered waveforms with

NCEDC events (15476 events, 1068275 SAC traces)

SAC Header update with meta data and catalog picks, homogenization of SAC files, organization

in event directories (by ID) and renaming according to ISNet scheme, and QC.

Re-picking:

Re-picking of P- and S-wave first arrivals from NCEDC with an automatic AIC-based picker

around bulletin picks for quality control and for pick consistency (~270000 P and ~25000 S), and

for initial selection of high-quality subsets, e.g. for velocity model and for GMPE.

Missing information:

Well coordinates/trajectories,

detailed injection/production information (some cumulative data is available in reports).



Database: Waveforms and meta data (README included; about 147 GB)

squeezer 172.16.25.105:/mnt/MyBook2T/datauser/GEISER/Geysers/

NCEDC Bulletin: Event catalog, phase readings (Hypoinverse format), and some fault planes (FPFIT)

Time: 10/1969 – 10/2011 (catalog) and 01/2000 – 10/2011 (picks and fault planes)

Region: 38.2° < Lat < 39.4° and -123.4° < Lon < -122.1° (about ±50 km around The Geysers)

Picks: About 270000 P-wave and about 25000 S-wave picks (validated by automatic repicking)

Waveforms: About 15000 events recorded at up to 31 3-C stations of the Berkeley-Geysers (BG)

network (surface, SM-6 or OYO GS-11D sensors, trigger mode, 2 ms sampling)

Format: Waveforms: SAC binary, sorted in event directories, file names as in ISNet database

Instrument responses: EVALRESP files for each channel

Time: 08/2007 – 10/2011

Region: 38.2° < Lat < 39.4° and -123.4° < Lon < -122.1° (15476 events)

38.7° < Lat < 38.9° and -123.0° < Lon < -122.6° (15140 events, virtually all with M>1)

Magnitude:minimum Md = -0.3 and maximum Mw = 4.5 (from NCEDC catalog)

Injection/production: One ACCDB file, but mostly scanned reports and tables (years 1969 to early 2009)

Other data: Station coordinates (ASCII), Quaternary faults from USGS (ESRI Shape, ASCII)
