Associated Natural Gas

Definition

Associated natural gas is natural gas found alongside crude oil in underground reservoirs. It is extracted as a byproduct during the oil production process. This gas can be separated from oil at the surface and either processed for sale or utilized for other purposes.

Operationally, associated natural gas can be processed into pipeline-quality gas or natural gas liquids (NGLs) for commercial distribution. In situations where infrastructure is lacking, some gas may be flared, burned at the site, due to safety or environmental reasons.

Associated natural gas is predominantly found in traditional oil fields and offshore platforms where both oil and gas coexist in the same reservoir. This occurrence is common where oil reservoir conditions enable the natural gas to dissolve within the oil under high pressure.

In simple terms, associated natural gas is a natural byproduct of oil extraction that can be utilized or flared depending on available infrastructure.

Significance in Energy & Investing

Associated natural gas contributes significantly to the global energy supply by providing an additional source of fuel extracted alongside oil production. It supports the overall efficiency of oil operations by enabling the commercialization of gas that might otherwise go to waste.

In terms of operations, associated natural gas extraction can increase revenue from oil fields by converting what could be considered a waste product into a marketable commodity. Facilities such as gas processing plants, storage facilities, and transportation pipelines are involved in handling associated natural gas, enhancing the economic viability of oil production.

Regulations is central to managing associated natural gas operations. Agencies like the Environmental Protection Agency (EPA) regulate flaring practices to minimize greenhouse gas emissions. For instance, the Bakken formation in North Dakota has seen initiatives to reduce high flaring rates by developing infrastructure to capture and market the gas.

As the energy transition intensifies, associated natural gas offers a bridge between traditional fossil fuel operations and more sustainable practices by providing a cleaner-burning option when compared to coal.

Implications for Investors

For investors, associated natural gas presents financial opportunities and challenges. It can increase revenue and improve cash flow from oil fields by adding a new income stream. However, the costs of developing infrastructure to capture, process, and transport the gas can affect capital expenditures (CapEx).

Investors should scrutinize company reports, particularly those detailing active gas capture and sales strategies. A company's ability to manage flaring and regulatory compliance, as reflected in filings or operational updates, can impact its reputation and financial performance.

Direct investors in mineral rights should understand that associated natural gas can influence lease operating expenses (LOE) due to the additional costs and revenues from gas production.

A common misconception is that all associated natural gas is flared, while in fact, many operations now have infrastructure to monetize the gas effectively. Flaring often occurs in remote locations lacking the necessary pipelines or processing facilities.

Red flags for investors include high levels of flaring, indicating potential infrastructure limitations or regulatory issues that could impede profit maximization. Aging infrastructure can also signify upcoming capital needs and potential risks.
