Abstract

A play-based resource assessment of conventional hydrocarbons has been performed for the Labrador Sea – Davis Strait continental shelf area, West Greenland (Assessment Unit 1, AU1). Four play levels have been assessed, with an estimated mean for the undiscovered resources of ~4,150 MMBOE risked recoverable for the northern area and ~1,400 MMBOE risked recoverable for the southern area based on the areal yield for the northern area.

The known prospectivity in the northern area includes 79 leads and 69 unevaluated features (fractured basement traps and stratigraphic traps) with Mean Case Risked Recoverables volumes of ~1080 MMBOE. The unidentified prospectivity has Mean Case Risked Recoverables volumes of ~3070 MMBOE resulting in an average area yield of ~30 MB/1000 km2 (risked). The unrisked Pmean volumes for the leads of the four evaluated play levels range from <1 to 1350 MMBOE.

The geologic probabilities for AU1 were determined based on careful play mapping constructing a series of numeric CRS (Common Risk Segment) maps and CCRS (Composite Common Risk Segment) maps of the assessment area. In this manner, the probabilities are consistently applied throughout the area for both the known and unknown prospectivity.

The assessment results presented are based on all available data collected and interpreted by the industry, GEUS, NUNAOIL and the Greenland Ministry of Industry, Energy and Research (MIER) and reflect the state of geologic knowledge of the West Greenland part of the Labrador Sea - Davis Strait area at the time of the assessment. Any future drilling and evaluation of the petroleum systems and plays based on new data within this area will add to the geologic knowledge, and will therefore lead to a refinement of these
assessment results.

The assessment was carried out using the Player® GIS software provided by GIS-pax. The methology and results of the assessment have been quality controlled by the Norwegian Petroleum Directorate and GIS-pax.

The results of this study are reported in an extensive ArcGIS project supported by a comprehensive slide package which includes 11 presentations, reflecting the workflow of the project, including:
• Introduction
• Database
• Structural Framework
• Seismic-Stratigraphic Framework
• Stratigraphic Evolution
• Petroleum Systems
• Post-Well Analysis
• Plays Analysis
• Lead Overview
• Input Parameters
• Yet-to-Find Analysis

The Player and ArcGIS projects together with the slide pack are available for the petroleum exploration industry at no cost and can be downloaded from the project website
