n: an agreement whereby the owner of a lease who does not wish to drill at the time agrees to assign the leasehold interest, or some part of it, to a third party who does wish to drill, conditional on the third partys drilling a well within the expiration date of the primary term of the lease. The assignment may include the entire interest together with dry hole money, or partial interest or entire interest with or without an override. If an override is retained, the owner of the lease may retain an option to convert such overriding royalty retained to an agreed-upon working interest. A farmout is distinguished from a joint operating agreement by the fact that the partner farming out does not incur any of the drilling costs. The primary characteristic of a farmout is the obligation of the third party to drill one or more wells on the farmout acreage as a condition prerequisite to completion of the transfer of title to such third party.
