Investing in the oil and gas industry carries a number of significant risks, including commodity price volatility risk, cutting of dividend payments for those companies that pay them, and the possibility of an oil spill or another accident during the production of oil or natural gas. However, long-term investments in oil and gas companies can be highly profitable as well. Investors should understand the risks fully before making investments in the sector.

Price Volatility Risk

The main risk for investing in the oil and gas sector is the volatility of the prices for the commodities. The industry has encountered a great deal of volatility in 2014 and 2015 due to a supply glut of crude oil and natural gas. The high levels of supply have hurt stock prices.

The price of crude oil dropped substantially during this time. Oil went from over $107 a barrel in July 2014 to around $42 in March 2015. Natural gas also followed suit going from $4.80 per one million British Thermal Units (mmBtu) in June 2014 to around $2.40 per mmBtu as of October 2105, a drop of around 50%. Natural gas is notorious for being very seasonal and volatile in its price due to greater demand during the winter. However, the drop in the price of crude oil caught many off guard.

The entire sector has been hurt by the lower commodity prices, not just those companies that engage in the exploration and production of oil. Oilfield service providers and drilling companies have been hurt by lower demand for their services as production companies are not able to earn as much revenue because of the low prices.

Dividend Cuts

Companies in the oil and gas sector often pay dividends. These dividends allow investments in those companies to make regular income. The dividends are therefore attractive to many investors. However, there is a significant risk that the dividend can be cut if the company is unable to earn enough revenue to fund the payments to investors. This risk is intertwined with that of low commodity prices. If companies earn less revenue from the sales of their products, they are less likely to be able to fund regular dividend payments, and there is a greater likelihood of a cut.

For example, Seadrill, an operator of drilling rigs, cut its substantial dividend payment in November 2014, and the price of the stock dropped by over 50%. The cut took many investors by surprise, and it highlights the risk associated with a dividend cut. Investors in the company lost out on a regular dividend payment, and they also lost a big chunk of the value of their shares.

Oil Spill Risk

Another risk in the sector is that a company could have an accident, such as an oil spill. This type of accident can cause a company’s share price to go into free fall.

BP saw its stock fall in the wake of the Deepwater Horizon oil spill in 2010. The stock was trading around $60 prior to the spill and dropped to as low as $26.75, a decline of over 55%. The Deepwater Horizon oil rig exploded and sank, leaving a sea-floor oil gusher that released over 4.9 million gallons of oil into the Gulf of Mexico. The oil spill had a severe negative impact on marine life and habitats in the Gulf. BP is still dealing with lawsuits and other issues from the incident years later.

In contrast, Exxon's stock did not fall that much after the Valdez incident in 1989. The Valdez tanker ran aground in Prince William Sound in Alaska, spilling over 11 million barrels of oil into the water. Exxon’s stock went down 3.9% in the two weeks after the spill and it recovered those losses after a month. The Valdez spill physically released less oil into the water. Still, the impact of the Deepwater Horizon spill on BP's stock price shows how such an incident causes a major decline due to the availability of information in the connected age, along with the impact of the 24-hour news cycle. The possibility of any future spills or other incidents may be a larger risk than it has been in the past.
