  1. A landman is using GIS to track lease expiration dates and wants to highlight leases expiring within 90 days in red. Which GIS technique accomplishes this?

    Answer: Definition query with temporal attribute symbology

    A definition query filters records based on attribute values (like expiration date), and attribute-based symbology then displays those filtered features in a specified color to flag imminent expirations.

  2. Which of the following GIS operations would best help a landman identify all surface owner parcels that would be accessed by a proposed pipeline corridor?

    Answer: Select by location using a spatial intersection

    Select by Location with an intersection relationship identifies all parcel polygons that overlap the pipeline corridor polygon, enabling the landman to compile a list of affected surface owners.

  3. In oil and gas GIS, what does 'AMI' stand for and how is it represented spatially?

    Answer: Area of Mutual Interest, typically represented as a polygon defining a joint acquisition zone

    Area of Mutual Interest (AMI) is a contractual zone defined between joint venture partners, mapped as a polygon in GIS to delineate where parties have rights of first refusal on future acquisitions.

  4. A landman uses a GIS web portal to view lease data remotely. Which technology most commonly enables browser-based GIS map viewing without installing desktop software?

    Answer: Web Map Service (WMS) or REST-based web map applications

    WMS and REST-based web mapping applications (like ArcGIS Online or ArcGIS Server) deliver GIS maps through standard web browsers, enabling remote access to lease and land data without desktop software.

  5. Which attribute is essential in a GIS lease polygon feature class to enable proper linkage to a land management system's lease records?

    Answer: A unique lease identifier field that matches the land system's primary key

    A unique lease identifier (such as a lease number or API-equivalent ID) is essential to join GIS spatial data to land system records, enabling integrated tract management and title chain queries.

  6. What is 'remote sensing' and how does it benefit oil and gas landmen?

    Answer: Acquiring land data from satellite or aerial imagery to monitor surface conditions and identify features

    Remote sensing uses satellite or aerial imagery to monitor surface conditions, detect unauthorized encroachments, identify infrastructure, and support environmental compliance assessments relevant to land operations.

  7. A landman must calculate the net mineral acres owned within a 640-acre section where the company holds a 50% mineral interest. If GIS calculates the gross polygon area as 638.7 acres, what is the net mineral acreage?

    Answer: 319.35 acres

    Net mineral acres = gross acres × decimal interest, so 638.7 × 0.50 = 319.35 net mineral acres, using the GIS-calculated area rather than the idealized 640-acre section.
