INTRODUCTION

The API Southwestern District Study Committee on Casing Landing Practice* was organized in March, 1952. Its objective was "to prepare a recommendation on a standard procedure for landing and hanging casing from the time the cement plug hit bottom until the time the casing hanger was installed and the casing set on the hanger, being held by slips or threads." Preliminary activity included considerable investigation of past reports, records, and correspondence covering the subject and a questionnaire was circulated to the industry in the southwestern United States. A summary of the data obtained by the questionnaire is presented as Table 1.

More detailed information on committee activity and discussion appears on p. 10-15 in "Reports of Meetings, Southwestern and Mid-Continent District Drilling and Production Practice Committees," API Circ. D473, May 10, 1954.
