==Slim hole completions==

In certain reservoirs, the economic value of the reserves does not justify the expenditures of normal completion methods. An example of such a reservoir would be a series of thin, small lenticular dry gas intervals. Under certain conditions, the reservoir might not warrant the use of large production casing and tubing to produce the gas. For such reservoirs, slim hole completion techniques might be justified in which small pipe, such as 4-1/2-in. or 2-7/8-in. casing, is run and cemented in the wellbore. This small casing serves as the tubing and casing for the wellbore. This completion practice is used to minimize completion costs and should be used only for wells that are expected to have short producing lives and that do not require artificial lift.
