Up until a few weeks ago, I had been working off the RStudio version I had initially downloaded in December 2015. The most recent version has a cool feature: tear-away source.

However, some state regulators have readily available rig count data. North Dakota is one such state.

I will be using McIntosh’s example except I will be working with Texas data (of […]Read more "2016 Texas Primaries: Mapped"
Where? Found some really awesome R cheat sheets courtesy of RStudio at this link. My favorite cheat sheet is Data Wrangling with dplyr and tidyr. Those two packages, by far, are the most useful CRAN packages for converting datasets into “tidy” data (normalized data). What? In case you missed it, R is the de facto data analysis programming-language, […]Read more "R you in need of help?"
What is geosteering? Geosteering is the esoteric art of squiggly-line matching. Ok, that may be an unfair summary, but for US-onshore horizontal wells, geosteering is the essence of proper well positioning. Really, what is it? For US-onshore horizontal wells, geosteering is the real-time correlation of real-time drilling data against offset well data. Geosteering is done […]Read more "Geosteering: Part I – Introduction"
