Questions people ask

What is on the Mountainside Energy Operating, L report card?

the scale and direction of its output, leases it gained and left and who buys and moves its production. 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 Mountainside Energy Operating, L 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).
