Reduce Your Oil Exploration Risk

International oil and gas companies are presented with so many exploration opportunities that they cannot all be actively pursued. In order to decide where to commit resources the exploration opportunities need to be analysed and ranked (preferably as quickly as possible), based upon the quality of each opportunity and the risks (geologic, engineering and economic) associated…

Shale Gas Well Reserve Mapping with GIS

Unconventional Gas The interest in unconventional gas exploration has significantly grown over the last decade following advances in drilling technology and exploration methods for monitoring and extracting unconventional gas [1,2,3]. Shale Gas has now become a target for new exploration and exploitation. Recent articles indicate the increase in the amount of Shale Gas plays that…

Tip 7: Convert Date Formats

We sometimes find datasets containing attribute data that we can’t use effectively because the data is not stored correctly.  A common example is a field containing dates where the field type is defined as ‘Text’. This results in difficulties filtering the dataset by date, e.g. “display data older than X”.  In this petroleum GIS tip we take the common…

Around 2800 Blocks in 80 days

The UK government launched its 26th offshore oil and gas licensing round last week.

In part 2 I’d like to present and discuss a couple scenarios that I came up with. Scenario Modelling Scenario 1 –…

Landfill Sites vs. Acreage: Worlds Apart?

As if running a GIS business wasn’t hard enough work, I recently signed up for a part-time MSc course, run by UNIGIS. One of the fun things about a course like this is that it takes you in to areas you wouldn’t normally venture. One of the exercises I’ve just completed was to identify potential landfill…

Tip 5: GDB Attribute Domains

Attribute Domains for ArcGIS File Geodatabases are arguably the most important data quality tool for geoscientists creating play fairway mapping data. As such we thought it would be useful if the next in our series of GIS Tips explained how to use them. There are probably three types of ArcGIS users reading this: Users that already understand…

Santa’s Ballistic Delivery System

“So,” said Santa, his grin widening, “we can get rid of the reindeer?”. He pushed back from his desk and turned to gaze through the glass wall that separated his office from the staff canteen. The reindeer sat together at one of the long tables that were arranged in rows in the canteen. They weren’t…
