He called CGV "the cheapest stock left in the group," and recommended it as a buy on growth alone. He said that if Congress lifts the ban on additional off-shore drilling, it would be a windfall for CGV.

Cramer brought up the use of so-called subsea Christmas trees in offshore drilling. He said the trees are effective in making drilling safer and cleaner because they help control the flow of oil and gas as well as other fluids used to regulate pressure to reduce the chances of an oil spillage. He said the increased use of these trees and their connection to a single manifold helps oil companies reduce the number of rigs needed at the surface. Cramer said the market leader in this technology is an old favorite of his: FMC Technologies(FTI).

Cramer first recommended Oceaneering on May 17, 2006 at $34.24 a share. Since then, the stock has gained 128% in value. Cramer still considers the stock a buy, especially after the company's 5.4% pullback Tuesday. "This is the stock to own for a resurgence in offshore drilling," he said.

Cramer recommended Smith International(SII) as a drilling-fluid play. He said the fluids are profitable to sell and have been successful in highly regulated areas like Europe. He said Smith and two other companies make up a drilling fluid oligopoly, making the stock more attractive. The company has also issued a 15-million buyback authorization, Cramer said, which means it's a great stock. "If you buy it now, you're getting it for less than you would have two days ago," Cramer said. He said the company is "thrice blessed," and part of one of the few bull markets right now.

Hornbeck makes offshore support vessels (OSVs) that are the lifeblood of offshore drilling. OSVs enable rigs to stand in the right position during extreme weather so they don't float away and jeopardize operations. As more rigs move offshore, they become more isolated and OSVs help in bringing supplies and removing waste. They are equipped with firefighting equipment and help with repairing rigs. There's a shortage of OSVs right now and there's a need to update these vessels. With the second largest fleet off the Gulf of Mexico, Hornbeck is in a position to command better rates for their OSVs.

Cramer told investors to buy Bristow Group (BRS) for a play on clean offshore drilling. The company contracts out the helicopters that move workers out onto offshore oil platforms. Cramer pointed out that more off-shore rigs are venturing out into deeper waters abroad, and this should help to increase demand for Bristow’s services. High demand for large helicopters in Iraq is also helping the company. Cramer said that barriers to entry in this market are high, which gives Bristow pricing power.
