United States Oil and Gas Boards

In the United States, oil and gas boards and commissions are the place for finding data related to oil and gas activities. These activities include well records, permitting, and production records. The list below covers nearly every state. You can add another state organization to this list.

International Oil and Gas Boards

International oil and gas boards operate similarly to United States oil and gas boards and commissions. This is the place to find information and data about oil activities in a particular country. You can add oil and gas board websites to this list.

Natural Gas Basics

Natural gas, commonly referred to simply as gas, consists chiefly of methane. It is frequently found with other hydrocarbon fuels such as oil, in coal beds, and as methane clathrates (ice-like solids in which a large amount of methane is trapped within a crystal structure of water). There are two main mechanisms by which the majority of natural gas forms: biogenic and thermogenic. Biogenic gas is released as a metabolic byproduct of microorganisms that live in anoxic (without oxygen) conditions, such as in bogs, landfills, marshes, and shallow sediments. Thermogenic gas is created by the decomposition of buried organic material deep within the earth at high temperatures and pressures.

Oil Basics

Oil, also known as petroleum or crude oil, is the preserved remains of prehistoric zooplankton and algae that settled to the bottoms of seas and lakes millions of years ago. Under anoxic conditions (meaning no oxygen was present), this organic matter combined with mud and became buried by layers of sediment. As the layers began to accumulate, they grew increasingly heavy, generating intense heat and pressure. This heat and pressure caused the zooplankton and algae to change: first forming kerogen (an organic compound that is found in various oil shales around the world), and then, with increased time, temperature and pressure, producing oil and natural gas through a process called catagenesis (a term used to describe the breaking down of complex organic molecules into simpler ones). To recover this oil and natural gas from deep within the earth, drilling is required. Once brought to the surface, it is refined and separated, and can then be used to make many of the products we rely on today.
