The LOD contains mineral rights data from hundreds of counties. To understand a little about the dataset, you need to first grasp how we describe it.
County –
The name of the county where the working interest, overrides and mineral rights are found. Often mineral rights are called ‘oil and gas royalties‘.
Year –
The year of the current data for that county. ie. 2010 means the data is from the 2010 tax year. Most data comes out in Fall, so 2010 data would normally be available around September 2010 and will remain the best data available until August 2011.
Count of Parcels –
Each county dataset contains a list of all the owners of record that own some oil or gas interest within that county. A single interest in an oil or gas asset is called a ‘parcel’. This ‘count of parcels’ is the total count of parcels within the county. For example, a county has 5,432 parcels, that means there are 5,432 separate interests in that county. John Doe may own interests in 6 wells, and those will represent 6 parcels in the dataset. A particular well might have 20 owners, these will show as 20 separate parcels.
Overall, the parcel count will give a good idea of how many wells are in a county and the number of people owning wells.
