Treasure Hunt with Maps & Apps

Exprodat recently held its first company day of 2015 and it was a great success. It’s a day filled with company updates from the Exprodat management team, technical workshops, team meetings and team-building social events. I’m on the Sports and Social Committee and we always try to plan a fun activity as part of the…

Improving Map Service Performance

In this blog we will look at how you can improve the performance of your ArcGIS for Server-based WebGIS applications by tweaking the content of the map services that they use. Before you start If you’re creating a new WebGIS application, or looking to amend an existing one, you should consider: Who’s going to use…

5 Key Messages from the 2015 EPC

5 Key Messages from the 2015 EPC

This was the third year that Esri has focused in on the ‘Location (Web GIS) Platform’ concept in their Partner Conference, and there was a real clarity around the messaging this year. These are my top 5 takeaways. 1. It’s not about the technology There was a clear shift away from a focus on technology,…

Survey results: GIS in Oil & Gas

Exprodat carried out its second industry benchmark survey in 2014, measuring geospatial capability maturity across 18 oil & gas operators worldwide (including Independents, IOCs and NOCs). Initial results were presented at the European PUG conference in November, and we are now pleased to make the full report available free of charge. From GIS resourcing levels…

1-hour Monograph 3

Introduction How long does it take you to run a “Monograph 3” geostatistical reserves analysis? Chances are that you find it complex, onerous and time consuming. If that’s the case, then you’re probably not using the right tools. In this blog I’m going to describe how I used GIS to run 10 iterations of the…

Displaying every Nth Feature

Scale is one of the most important factors to consider when representing data on a map. As mentioned in the ‘Creating a Multi-scale Geological Map’ blog it is important not to confuse the message of your map by including too much data. There are several ways of controlling scalable visibility, including: Using separate datasets of…

Calculating Depth to Surface from Contours

Calculating Depth to Surface from Contours

Depth-to-surface maps can be derived from isopach (thickness) data, and are useful for visualising regional structural trends. This blog demonstrates how to use mathematic functions in ArcGIS to create a grid representing the depth to a stratigraphic surface in the Viking Graben area of the UKCS (see previous blog for data and area). Method Calculating…

Python Codeblock Field Calculations

With the arrival of ArcGIS 10.0, Esri introduced the ability to use Python within the Field Calculator allowing the user the ability to perform more complex calculations. How does this help me? Let’s suppose I need to create a map showing the fields of the central North Sea in both the context of their hydrocarbon…

Making Elevation Profiles in 3D Analyst

Making Elevation Profiles in 3D Analyst

Introduction An elevation profile charts the elevation along a straight or irregular line. Their uses within the Oil and Gas industry include: Infrastructure planning – eg, pipeline routing Field work route planning Providing a topographic profile for use in geological cross sections.   In this blog I look at the construction of vertical profiles for…

GIS in Challenging Environments

Working in challenging environments: an example of using GIS and big data analytics to support safer O&G operations, understanding and managing risks In my last blog on the value of spatial analysis, I promised some examples showcasing the use of analytics for “Big Data” in the O&G and GIS space. To kick this off I…
