It’s funny – we’d never work from a well database that was out of date. In fact, we keep looking for new ways to get the current data faster and faster. Yet we often look at land grid as a static dataset – something you load up once and then ignore.
The thing is – it IS changing – every day. And while it’s not as obvious as, say, a new well license, it is just as important. And why is that? Well, something as seemingly minor as a refinement of a section corner position could, in fact, be the difference that lets you squeeze one more site into your well spacing, could be the difference that eases your way through the regulatory process, and, without question, ensures your maps are accurate as they can be.
What sort of changes occur? WhiteStar Grid is updated constantly, and those changes come from the best source available for a given location. When the BLM resurveys, when GPS coordinates become available, when the USGS reissues a map at a better scale, when alternate data sources emerge – say, a county’s local survey system – those changes are incorporated and delivered to you via updates. Texas is a particularly dynamic grid – one recent year saw on the order of 20,000 changes. With the incorporation of WhiteStar Lots and Tracts, the entire dataset is now benefitting from a whole new level of accuracy, and where GPS data is added, accuracy is down to the centimeter. Compare that with plus/minus 2,000 feet that can be found in available “free” data.
So how does one go about intelligently managing the update process? Do we need to rebuild our entire land base with each update? Luckily, no. Each grid polygon has an extensive set of metadata attached to it, including modification dates for the both the attributes and geometry. Change detection since your last update is a simple query, and only the modified data needs to be dealt with.
Grid does change – and regularly maintaining your internal updates will pay off in maximizing return on your leases and more. If you have any questions on how best to implement a grid update strategy, please do call us.
