The design, construction, startup, and operating phases of major projects involve several different people. Operating problems encountered subsequent to initial startup are not always communicated to designers. This can result in design errors being repeated and costly modifications being required after initial construction.
The intent of this paper is to review several operating problems encountered in producing the Hanlan Swan Hills gas field since startup in March 1983. These problems and the resulting recommendations should be considered in the design and operation of future deep sour gas systems.
