Project Geophysicist
CurrentSoftware Created:• Surfer Automation-Takes 2D or 3D inverted data files, parses relevant information, generates X, Y, Z slices, grids data and plots in Surfer-Plots basemap images with electrodes, X/Y lines and superimposed Z slices-Dynamically generates layout based on survey size(s)-user can choose slice generation with auto-generate, list of slices, start/stop/step methods-user can choose template or page size and colorbar• ER processing that takes raw Supersting and GPS files and prepares for inversion through Res2Dinv and Res3Dinv. Capabilities include:- Wenner, Schlumberger, dipole-dipole, pole-dipole and pole-pole array types- 2D surveys with 2D and/or 3D output, 3D surveys with 2D or 3D command files, bulk 2D processing, multiple 2D surveys concatenated into one 3D survey- Calculates apparent resistivity from resistance and points, plots on log scale along with measured resistivity pseudosection for user to parse data. Regenerates plots dynamically.- Single line or master GPS files- Ability to remove electrodes- Can specify 3D survey grid• GPS Processing- Takes state plane coordinate points, converts to WGS84 lat/long and pulls high resolution 1 meter DEM elevation datasets from USGS API, then crops data to specified bounding box and converts back to state plane- interpolates gps data based on points and outputs csv files with raw and lidar elevations at each location- Generated geotiff and csv files can be dragged and dropped into Global Mapper or Surfer for interpretation• PaGWIS Driller log processing-Takes downloaded PaGWIS driller log spreadsheets and concatenates into a single file with no duplicate entries per well-Downloads hand written and digital logs, saves them as pdfs and creates combined pdfs for each-Generates statistical analyses on several items such as formations, lithology, depth, well yield and static water levelGeophysical data acquisition, processing and interpretation
