Using GIS To Manage Surface Ownership and Right-Of-Way
Daniel Whitworth - Assoc. Land Maintenance Rep. / GIS Data Analyst
Daniel has a masters degree in MIS/GIS and supports the surface ownership data model via data analysis and data management. He also provides technical support for the GIS analysts as well as the end users.
Jeff Bute - Sr. Land Maintenance Rep. / GIS Analyst
Jeff was formerly a Property Tax Right of Way and Claims field agent for the company. Now he uses his extensive right-of-way experience to coordinate the data acquisition process and supporting the end users.
The management of surface ownership can be a complicated task in order for an individual to get their arms around this subject one first needs to identify their task and understand what is available in order to meet their needs. At ConocoPhillips we have grouped the needs for ownership for our myriad of business partners that we serve so that we can supply the information necessary in a timely and cost efficient matter.
The ownership data that we acquire will typically support our Upstream, Downstream, Risk Management and Emergency Response business partners.

PipelineTable
Our primary objective for surface ownership is to support Right Of Way Activities. We use this table to organize and store the spatial pipeline features.
At ConocoPhillips, a tract represents a pipeline crossing a parcel. Each time a parcel is crossed by a different pipeline, anew tract is required. The tract table ties each pipeline systemto the parcels it crosses.
In order for a tract to exist, there must be a underlying parcel. The parcel table stores parcel specific information such as Situs Address, Data Source, County IDs, etc. This table is also a feature class, storing the spatial parcel features.
Ownership information is stored in a separate attribute table because each parcel may have multiple owners. This information includes Name, Mailing Address, Email, Phone, etc..
Some parcels may cross large spans of land or have complex legal descriptions. These cases prompt the need for a separate legal description table, allowing us to capture all of this information.
A parcel is the boundary of an owned piece of property. Parcels are obtained from the public data sources.
A tract relates individual parcels to company owned assets of interest, such as a pipeline.
(If you look above you will see 4 parcels, illustrated by the grey boxes.There are two pipelines crossing this area of the county.)
We use tracts to associate the ownership of the parcels along a given pipeline.

Simple but effective method, granting read only access to the ownership information. Allowing simple GIS
analysis.
Advanced GIS tools allow advanced spatial analysis with limited ownership
management via joining the oracle tables together.
System designed to facilitate ownership management as well as
end user workflows by automatically joining the ownership tables and tying
them back to individual company assets. This system also utilizes
versioning for disconnected field work, so individual edits can be made.
