Well Construction Interface Document Guidelines

1. Scope

   
   

   1. This bulletin provides guidance on information that is to be shared regarding well construction and rig- specific operating guidelines. It is intended to align the lease operator’s safety and environmental management system (SEMS) with drilling contractor’s safe work practices (CSWP).

      
      

   2. The well construction interface document (WCID) is used to formalize the exchange of information as shown in Figure 1.

      NOTE The WCID is not intended to duplicate the health, safety, and environment (HSE) information addressed by the lease operator’s HSE bridging document with the drilling contractor.

      
      

   3. The WCID-SEMS is a bridging document that includes the elements identified in API 75 within the context of well construction activities. It is understood that work processes vary between operators and contractors, which should be honored in the development of the WCID document.

      
      

   4. The intent of the bridging document between the lease operator’s SEMS and the CSWP is to provide:

1. an outline of responsibilities for the lease operator’s and drilling contractor’s personnel;

   
   

2. acknowledgement that management of change (MOC) and risk assessment processes should be used:

   
   

   • during well construction activities,

     
     

   • to address personnel or organizational changes to ensure personnel skill level is sufficient for the applicable position;

     
     

3. a vehicle for the drilling contractor to be involved when operational changes and/or conditions are identified that could require a well activity risk assessment;
