Professional Services Case Studies

Merrick & Company

Blue Marble assisted Merrick & Company of Aurora, Colorado to implement the Blue Marble GeoTranslate software development kit directly into Merrick & Company's MARS software for the purpose of reading and drawing vector-based CAD and GIS files. In order to do so, Blue Marble technical staff used and modified the MARS source code on the Windows-based development platform Visual Studio VC++ 2003. Blue Marble also customized our GeoTranslate software development kit to read/display the LiDAR (LAS) coordinate reference system (v1.1 and v2.0) for the purpose of reprojecting and translating LAS files to other supported vector-based CAD and GIS data types.

Seismic Micro Technology

Blue Marble worked with Seimic Micro Technology (SMT) of Houston, Texas to implement upgrade support for the GeoCalc software development kit as part of The Kingdom Suite (TKS) coordinate transformation utility. The Blue Marble Development Staff broke down the current set of used GeoCalc classes, and mapped these old classes to a new set of (GeoCalc v6.4) classes and dialogs. This designed a mechanism for transforming old CRS (Coordinate Reference System) and DS (Data Source) objects into new GeoCalc objects. Delivery consisted of an upgraded geodetic Data Source that contains CRS definitions for legacy SMT CRS and datum transformations. Blue Marble also provided a roadmap for upgrading the TKS software to use current GeoCalc 6.4 reprojection calls. The Blue Marble User Interface allowed TKS users to select CRS definitions and deprecate selected forms. The updated installation file upgraded the existing Blue Marble definitions and removed older GeoCalc v5.x files.

Colorado Oil & Gas Conservation Commission
Directional Well Bottom Hole Location Mapping Project Updates

Blue Marble originally performed custom software development work for the Colorado Oil & Gas Conservation Commission as a professional services engagement. The original work product was a stored procedure in SQL-Server that calculates the lat long of a directional well bottom hole location based on the lat long of the surface location and an X_Y offset (in feet) from the surface location. The assumption is made that the lat long is calculated based on a North Reference of TRUE NORTH in the previous work product. In 2010 Blue Marble performed enhancements to the original project. This involved obtaining directional surveys from the Colorado Oil & Gas Conservation Commission that report X-Y offsets (feet) from the surface location with respect to GRID NORTH. This 2010 project adjustment included Colorado Oil & Gas Commission’s need for the previous procedure to check for a Grid North Reference and calculate lat long using the x-y offsets and the true north convergence angle (usually not more than 2 degrees).
