AbstractTwo challenges facing operators as the energy industry moves into the next century are accessing of new reservoirs that currently cannot be reached economically and maintaining profitable production from older fields. Recent advances in one of the oldest and most fundamental areas of exploration and production, namely tubular technology, will play a key role in meeting these challenges.A method has been developed whereby the diameter of solid tubulars can be expanded downhole. This paper will describe the process and how this significant technological breakthrough provides cost-effective solutions to several tubular problems that have loomed as obstacles to comprehensive reservoir exploitation. In deepwater and subsalt environments such as the Gulf of Mexico, the ability to expand casing and tubing in-situ enables hole-size maintenance and conservation of internal tubular diameter for increased efficiency. Hence, operators are less likely to run out of hole diameter before evaluating all pay zones. Operators can now use smaller holes to drill deeper vertical wells or to extend the reach of deviated wells to access untapped reservoirs. In older fields, existing wellbores can be retrofitted with expanded tubulars for repair purposes or to increase strength and integrity. In the latter case, deeper high-pressure objectives can be supported, and thus, new in-fill wells can possibly be reduced in number or even eliminated.In addition to a description of the process employed to expand solid tubulars, the paper will present applications of expandable tubular technology and results of large-scale testing that has been conducted in support of the applications. Potential commercial applications are also presented.

The results of a 1981 survey of 302 Caribbean sugarcane cutters who were temporary immigrants in Florida are presented. The focus is on remittances to the islands of origin. The results provide "no evidence that seasonal stateside employment expands agricultural output, or enhances the productive capacity of small farmers in the Caribbean."

Expansion of temporary worker programs has figured prominently in recent proposals to reform United States immigration policy. The Florida sugar cane industry has been using foreign workers from the English-speaking Caribbean since 1943. The 8000 to 9000 workers annually admitted under section H-2 of the 1952 Immigration and Nationality Act to cut cane constitute the largest legal nonimmigrant labor force in the United States. Examination of the Florida H-2 program reveals that existing temporary worker policy is ambiguous, if not contradictory, on the issues of the displacement of domestic workers; the characteristics and value of H-2 workers; their impact on local communities in the United States; and the effects of seasonal labor migration on the migrant and his country. Suggestions for improving policy include strengthening of statutory guidelines and administrative agencies, adoption of a more market-sensitive adverse effect wage rate, making farm labor more attractive to American workers, removing distinctions between foreign and domestic workers, and measures to improve the lot of the migrant and his home society.
