NEW YORK (TheStreet) -- Shares of Oasis Petroleum Inc. (OAS) - Get Report are down by 7.18% to $12.93 in mid-morning trading on Monday, as some stocks within the oil and energy sector take a hit today after the commodity's price reached a six-year low.

Crude oil (WTI) is falling by 3.39% to $43.32 per barrel and Brent crude is declining by 3.15% to $52.95 per barrel this morning, according to the index provided by CNBC.com.

Oil prices are being driven into the red today on speculation that the record U.S. supply may start to burden the country's storage capacity, Bloomberg reports.

U.S. crude tankers may fill up as cuts in the number of drilling rigs fail to slow down production growth this year, the International Energy Agency has estimated, Bloomberg noted.

Also pushing oil prices lower today is the possibility of a nuclear deal with Tehran, which could result in more oil exports out of Iran, Reuters reports.

Western countries are looking for concessions from Iran that could aid in securing an agreement in nuclear discussions, after the U.S and European powers expressed a willingness to work out suspensions of U.N sanctions.

Separately, TheStreet Ratings team rates OASIS PETROLEUM INC as a Hold with a ratings score of C. TheStreet Ratings Team has this to say about their recommendation:

"We rate OASIS PETROLEUM INC (OAS) a HOLD. The primary factors that have impacted our rating are mixed some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its compelling growth in net income, notable return on equity and reasonable valuation levels. However, as a counter to these strengths, we also find weaknesses including generally higher debt management risk and a generally disappointing performance in the stock itself."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

• The net income growth from the same quarter one year ago has significantly exceeded that of the S&P 500 and the Oil, Gas & Consumable Fuels industry. The net income increased by 223.9% when compared to the same quarter one year prior, rising from $54.49 million to $176.50 million.
• The company's current return on equity greatly increased when compared to its ROE from the same quarter one year prior. This is a signal of significant strength within the corporation. When compared to other companies in the Oil, Gas & Consumable Fuels industry and the overall market, OASIS PETROLEUM INC's return on equity exceeds that of the industry average and significantly exceeds that of the S&P 500.
• Regardless of the drop in revenue, the company managed to outperform against the industry average of 19.6%. Since the same quarter one year prior, revenues fell by 10.2%. The declining revenue has not hurt the company's bottom line, with increasing earnings per share.
• OAS's stock share price has done very poorly compared to where it was a year ago: Despite any rallies, the net result is that it is down by 65.59%, which is also worse that the performance of the S&P 500 Index. Investors have so far failed to pay much attention to the earnings improvements the company has managed to achieve over the last quarter. Naturally, the overall market trend is bound to be a significant factor. However, in one sense, the stock's sharp decline last year is a positive for future investors, making it cheaper (in proportion to its earnings over the past year) than most other stocks in its industry. But due to other concerns, we feel the stock is still not a good buy right now.
• The debt-to-equity ratio of 1.44 is relatively high when compared with the industry average, suggesting a need for better debt level management. Along with this, the company manages to maintain a quick ratio of 0.44, which clearly demonstrates the inability to cover short-term cash needs.
