Recommended Practices for Diverter Systems Equipment and Operations
|Publication Date:||1 July 1991|
1.1 The purpose of these recommended practices is to provide accurate information that can serve as a guide for selection, installation, and operation of diverter equipment systems on land and marine rigs (barge, platform, bottom-founded, and floating). Diverter systems are composed of all subsystems required to operate the diverter under varying rig and well conditions. A general description of operational procedures is presented with suggestions for the training of rig personnel in the proper use, care, and maintenance of diverter systems. Refer to Appendix A for discussion of some alternative methods for shallow gas well control.
1.2 Some operations are being conducted in areas of extreme low temperatures. Since current general practices usually result in protecting diverter systems equipment from that type environment, an applicable section has not been included for that service.
1.3 Recommended equipment installations, arrangements, and operations as set forth in this publication are deemed adequate to meet specified well conditions and intended uses. Examples presented herein are simplified embodiments and are not intended to be limiting or absolute. These recommended practices have been prepared recognizing that alternative installations, arrangements, and/or operations may be equally as effective in meeting well requirements and promoting safety of drilling personnel, public safety, integrity of the drilling equipment, protection of the environment, and efficiency of ongoing operations.
