Drilling Performance Metrics Study

The Drilling Performance Metrics study by NSB Energy out of St. John’s was commissioned by Nalcor Energy to provide a synopsis of historical drilling performance in the NL Offshore for the global industry.

In August 2016, Nalcor Energy – Oil & Gas released the results of a drilling metrics study. The reporting is not a drilling offset study, but rather a compilation of historical reports presented in a clear, comparable and easily accessible format. This report provides a summary of well data and drilling metrics obtained for 112 of the 167 exploration wells that have been drilled offshore Newfoundland and Labrador since 1966.

The study is a comprehensive compilation of data from publicly available reports on exploration wells drilled in Newfoundland and Labrador’s offshore. Its footprint covers the most northerly points of offshore Labrador, to the waters comprising the southern extents of the province’s jurisdiction. This vast area has been divided into four separate regions for ease of analysis and comparison purposes: Labrador (with Labrador North and Labrador South sub-regions), Eastern Newfoundland, Jeanne d’Arc Basin, and South Newfoundland. The individual reporting provides analysis of 112 exploration wells drilled in the Newfoundland and Labrador offshore. Through drilling performance indicators such as rate of penetration (ROP), water depth, total drilled depth, drilling fluid type and amount of non-productive time (NPT), this study provides the ability to compare drilling metrics of individual wells in a particular region, but also compare the separate regions themselves. This report also provides a review of the drilling rigs that have been used in Newfoundland and Labrador’s offshore, research on a number of drilling rigs currently available, and an analysis on how each rig type could perform.

nsb_logo To facilitate the use of this vast dataset, Nalcor has used the Nalcor Exploration Strategy System (NESS). This system was developed in 2013 to capture insights from data collected within the exploration team. The NESS system is a web-based, interactive database or Geographic Information System, which includes the drilling performance data presented in this report as well as other geographic and geophysical data of the Newfoundland and Labrador offshore.
