API RP 97L
Onshore Well Construction Interface Document
|Publication Date:||1 December 2020|
This document provides guidance on information that is to be shared regarding onshore well construction and rig-specific operating guidelines. It is intended to align the lease operator's and drilling contractor's safety and environmental management systems (SEMS).
The WCID is used to formalize the exchange of information as shown in Figure 1.
NOTE The WCID is not intended to duplicate or supersede existing bridging documents developed by the lease operator and the drilling contractor.
The WCID is a bridging document that includes the elements identified in API 75L within the context of well construction activities. It is understood that work processes, which are addressed in the development of the WCID document, vary between operators and contractors.
The intent of the bridging document between the lease operator's and drilling contractor's SEMS is to provide:
a) an outline of responsibilities for the lease operator's and drilling contractor's personnel;
b) acknowledgement that MOC and risk assessment processes should be used
- during well construction activities, and
- to address personnel or organizational changes to ensure personnel skill level is sufficient for the applicable position;
c) a vehicle for the drilling contractor to be involved when operational changes or conditions are identified that could require a well activity risk assessment (e.g. change from overbalanced to underbalanced drilling or a change that affects a well barrier);
d) a method to align all parties regarding drilling HSE standards and applicable regulatory requirements;
e) a method of communicating stop work authority.
