Question 1

Which type of GIS analysis would a landman use to determine how much of a proposed lease block falls within a federally designated wilderness area?

Accepted Answer

Overlay analysis

Answer

Overlay analysis combines two or more spatial layers to identify areas of intersection, allowing a landman to calculate acreage of a proposed lease that overlaps restricted federal land.

Question 2

In GIS, what is a 'geodatabase' and why is it preferred over shapefiles for complex oil and gas land management projects?

Accepted Answer

A spatial database format that supports domains, subtypes, and topology rules

Answer

A geodatabase is a relational database structure for GIS data that supports advanced features like attribute domains, relationship classes, and topology rules, making it superior to shapefiles for managing complex lease datasets.

Question 3

A landman needs to locate a well described as being in the SW/4 of Section 12, T2N, R3W. What GIS tool would most efficiently identify the correct 40-acre parcel?

Accepted Answer

A PLSS-based spatial query against a BLM GCDB layer

Answer

A spatial query against a BLM GCDB PLSS layer using township, range, and section attributes allows a landman to precisely locate and select the described quarter-section parcel.

Question 4

What is the primary purpose of a 'digital elevation model' (DEM) in oil and gas GIS applications?

Accepted Answer

To represent terrain elevation for pipeline routing and drainage analysis

Answer

DEMs represent terrain surface elevation as a raster grid and are used in pipeline routing, flood zone identification, and slope analysis critical to oil and gas operations planning.

Question 5

Which of the following best describes 'geoprocessing' in a GIS workflow for a land department?

Accepted Answer

Automated spatial analysis operations that manipulate, transform, or analyze geographic data

Answer

Geoprocessing refers to GIS operations like clipping, merging, buffering, and overlaying datasets to automate spatial analysis tasks such as identifying open acreage or calculating lease statistics.
