Spectraseis/ESG Solutions, Geophysicist I- 8/2018 – 9/2019 ESG Solutions through Present With this organization I had the opportunity to learn about ISM and other micro-seismic applications. I worked in ISM and GMM data processing as a Geophysicist I. The following points detail my key work experience at Spectraseis:

AWS and Git Administration:

Spectraseis/ESG was in the process of migrating all processes to AWS while during my employment with them. I was responsible for the cleanup and organization of Legacy projects under my management for the purposes of this migration. Preparing my projects required the cleaning up and organizing of data directories. I was required to understand the s6 server and how to wrangle data using terminal commands via BAS, for the most part. These terminal commands included r-syncing and transferring data via pem-key access to specific servers and similar tasks.

Spectraseis used Github for version control therefore I have experience tracking code and data table updates/transactions, with an appreciation for the importance of version control using Github. I was responsible for keeping track of many recurring updates to processing flows and project specific objects which required version control.

Code writing with multiple languages:

I was responsible for understanding and utilizing Java, JSON, MATLAB, and Python to accomplish my duties. For example: I developed my own Python Scripts to create linear regression plots for specific data and generate cross-plots for event catalog comparison. I used Python to scan large earthquake catalogs, over 3000 objects, to identify missing data and/or redundant data for the purpose of data cleansing. I used MATLAB script to perform meta-data fixing including EBCDIC Header re-writing of .sqy data and complex geophysical data modeling. I used Java and JSON API to build projects for use in the client portal. This involved setting up project processes to download data real-time and running local server projects in Eclipse IDE for project testing before implementing them in production on AWS.

ISM (Induced Seismicity Monitoring) and GMM (Ground Motion Monitoring):

I was primarily involved in ISM which included the visual QC and pick based analysis of hundreds of .sgy gathers daily. I compiled monthly reports providing details on seismicity and statistics/metrics on monthly earthquake catalogs. I managed Java projects for our client portal and defined/refined geophysical processing workflow algorithms. Additionally, this required me to understand GIS Applications and coordinate conversion using specific geographic projections. I would create .shp files using GIS software for client visualization and monitoring purposes. I would then use this information to define buffers using project xy minima and maxima for the purposes of alert automation. These workflows performed functions like gathering, cloud storage/persistence method setup, filtering, magnitude estimation via brune spectral fitting, and much more. In general workflow algorithms consisted of 30 or more algorithms.

I used Python and BASH to download various data from remote instruments in British Columbia, CN. I used MATLAB script to create spectral acceleration plots for GMM Reports. I was responsible for the overall management of multi-client FBA instruments, up to 10 instruments at a time. I was responsible for keeping track of instrument specific data. The instruments were in very remote locations and could not be reached during very specific timeframes based on weather and/or network activity. This required a high degree of project organization and data tracking on my behalf. I also delivered bi-annual reports on significant events within client operation buffers per BCOGC (British Columbia Oil and Gas Commission) standards. This required a long process of visual QC of seismic data and event tracking based on TRG time which was based on the instruments internal clock. This process included troubleshooting times for data loss. Many instruments had several hundred .TRG files and were unreliably calibrated which required me to use critical analytic skills to identify missing continuous .RBF and .TRG data.

Linux/Windows Workspace Administration:

I have advanced experience with Linux command line, using BASH terminal to create directories, control permissions, and transfer data. At Spectraseis we worked primarily in the Linux CentOS 7 and Windows 10 domains with a strong preference for CentOS 7. I was using the XServer tool, MobaXterm to SSH into secure servers and workstations on my remote workstation. Also, I have experience setting up dual boot Windows/Linux machines including HDD/SDD partitioning and GRUB boot loader on my previous workstation.

Project Management:

I managed up to 6 projects at any given time during my time at Spectraseis. These were surface ISM Array projects for clients such as: Shell, BP, Cimarex, and more. Daily responsibilities included the manual QC of hundreds of events per project, per day. I was responsible for maintaining multiple ISM Arrays of 20 or more stations/instruments at any instance. Maintenance involved coordinating field visits to remote sites, real-time troubleshooting with the maintenance team, and project planning for streamlining station moves.

Reporting:

I used software such as: MS Office Suite, LibreOffice, MATLAB, Python, and Madagascar/SepLib to create reports for client specific deliverables and requests. I was required to keep track of numerous reporting deadlines for various projects of different scope. These reports required: daily, weekly, monthly, bi-annually as well as yearly recurring deadlines. These reports included information on project metrics such as event frequency, magnitude, xy and other various parameters. Additionally, I have experience using FileZilla to access and share with FTP.

24/7 On-call Work Service:

I was required to rotate with other staff members for our 24/7 On-Call Service. While working as the On-Call Geophysicist, I was responsible for manual QC of real-time events and responding to clients within 30 minutes of the receipt of an alert at all times which included working throughout the night. I was responsible for responding with event information in accordance with client specific protocol. This required keeping track of various client protocol, up to 7 at a time, and delivering timely information with a high degree of accuracy while performing all other daily tasks during the On-Call period. Quite unexpectedly, the Denver group office was closed in 9/2019 due to the company’s reorganization however I currently work for ESG remotely from my home. Overall, this job experience has allowed me to: expand my technical knowledge of IT systems, broaden my understanding of applied micro-seismology, taught me how to think critically while managing multiple projects and how to adapt quickly in a fast paced technical/scientific work environment while maintaining excellent standards.
