FAQ

Questions people ask

What is on the Marathon Oil Ef LLC report card?

the scale and direction of its output, leases it gained and left, who buys and moves its production, the prices it told investors and its drilling permits. Each line says where it comes from: Railroad Commission records, SEC filings, or statements uploaded by owners, and there is no grade or rank.

When does Marathon Oil Ef LLC have to pay my royalties?

The first payment is due 120 days after the end of the month of first sale from the well. After that, payment follows your lease or written agreement, and if that is silent, no later than 60 days after the end of the month for oil and 90 days for gas (Natural Resources Code section 91.402).

Where do the owner figures come from?

From statements owners uploaded to Royalty Clerk. A figure appears only when 5 or more different owners are behind it, each owner counts once, and we show a middle value and the middle half, never one owner's line. Owners can opt out and the figures are rebuilt without them.
