Tip 19: Using Buffers to Model Lateral Migration

We often use ArcGIS Desktop’s buffer tool simply to select areas within set distances from a feature or features we are interested in.  However, buffering can be used in more complex ways such as to produce a set of concentric buffers – this can be useful when looking at suspected migration of petroleum away from mature kitchen…

Using GIS in Unconventionals Developments

Exciting times here at Exprodat as we prepare to release a new software tool for the “unconventionals” market. In anticipation of this I thought I’d provide a sneak preview of what’s coming… Unconventionals Analyst is a well planning and reserve forecasting application for unconventional resource projects.  Unconventionals Analyst was developed in partnership with a leading global…

Tip 18: Selecting From Multiple Areas

Selecting features in ArcMap is usually pretty straightforward, particularly when there are only a few records in a dataset. In such cases, the required features can simply be selected either from the Attribute Table, or from the map by clicking on an individual feature or “rubber-banding” multiple features. But when using layers where the features…

Environmental and Seabed Constraints Analysis in ArcGIS

GIS for environmental data management and analysis in E&P At Exprodat we recently carried out a review of GIS use in the environmental side of the oil and gas business with the participation of some of our clients. The results show that awareness of how GIS can support environmental data management and environmental analysis workflows…

Correctly Aligning Features in ArcMap: 3

In my previous posts (part 1 and part 2), I described how ArcMap warns users that a coordinate transformation is required and some potential pitfalls to be aware of. In this post, I will explain how to set a coordinate transformation in ArcMap. How to Select a Coordinate Transformation Open the Geographic Coordinate Systems Transformations…

Correctly Aligning Features in ArcMap: 2

In my last post (part 1), I described two scenarios when ArcMap undertakes coordinate operations, commonly known as “on-the-fly projection”.  In the second scenario, the user must select a valid coordinate transformation to ensure map layers are correctly aligned. In this post, I will outline how ArcMap informs the user a coordinate transformation is required…

Correctly Aligning Features in ArcMap: 1

As mentioned in a previous blog, ArcMap can correctly align layers of geographic data with different spatial reference (also called ‘coordinate reference system’ or ‘CRS’) properties within the same data frame.  This so-called “on-the-fly projection” leaves source data unchanged – it does not permanently change it in any way whatsoever. Using this functionality, companies avoid…

Making Movies with ArcGIS Explorer

In the plenary session of Esri’s PUG Conference 2011 they showed a video from Anadarko discussing GIS and introducing their ‘iMaps’ web-based GIS solution. In the video Anadarko explained that their philosophy was to provide ArcGIS Desktop for GIS-savvy users, and the web-based GIS ‘iMaps’ for basic use across the enterprise. Choosing the right tools…
