The co-owners of the Terra Nova project offshore Newfoundland have reached an agreement in principle to restructure the project ownership and provide short-term funding toward continuing the development of the Asset Life Extension Project, with the intent to move to a sanction decision in the fall. A subset of owners will increase their ownership of the project for consideration payable from the other owners. Full details of the ownership swap were not disclosed, however, as a result, operator Suncor's ownership will increase to 48% from around 38%. The agreement is subject to finalized terms and approval from all parties, including board of director approval where appropriate, and is contingent upon the previously disclosed royalty and financial support from the Government of Newfoundland and Labrador. "Over the past year, Suncor has worked diligently with all stakeholders to determine a path forward for Terra Nova," said Mark Little, Suncor president and chief executive officer.
Suncor Energy is preparing for all contingencies when in comes to the fate of the Terra Nova FPSO. The operator recently issued Expressions of Interest (EOI) related to the FPSO, including two that prepare for decommissioning of the vessel and the field, while another provides an update to a previous EOI preparing for remediation of the FPSO to support the asset life-extension project. The move has the Newfoundland and Labrador Oil & Gas Industries Association (NOIA) concerned about the future of the vessel and the field. "NOIA members and our Board of Directors are deeply concerned for the future of the Terra Nova Project and the far-reaching impacts decommissioning and abandonment would have upon our industry, the people who work in it, and our province," said Charlene Johnson, chief executive of NOIA. "I understand the deadline to reach a deal on the Terra Nova Project was extended to April 30--which has now passed--and NOIA is encouraging all parties to reach an agreement as quickly as possible."
Operations remain suspended on the SeaRose FPSO vessel following an oil spill at the White Rose field offshore Newfoundland and Labrador last week. Husky Energy, owners and operators of the vessel, reported the spill on 16 November following its decision to shut in oil production at White Rose the day before in anticipation of severe weather. A shut-in subsea flowline is believed to be the source of the spill, which occurred as Husky prepared to resume production. Husky said it deployed a remotely operated underwater vehicle (ROV) to inspect the flowlines and confirm the source of the leak. Since the original spill, no additional oil has been detected at the surface.
Hibernia Management and Development Company (HMDC) has again halted production from its 220,000-B/D Hibernia platform off Newfoundland and Labrador after another oil spill was reported 17 August. HMDC, an ExxonMobil-led consortium, had resumed production from Hibernia just 2 days earlier, ending a month-long shut down due to a first discharge. Husky Energy on 16 August also brought on stream for the first time since November 2018 its North Amethyst and South White Rose Extension drill centers at the White Rose field, where a failed flowline connector resulted in a 1,572-bbl spill--the largest-ever off Newfoundland and Labrador. "The nature and frequency of these incidents in our offshore area are obviously concerning," said Scott Tessier, chief executive officer of the Canada-Newfoundland & Labrador Offshore Petroleum Board (C-NLOPB), in a statement following the second Hibernia spill. "The C-NLOPB is focusing its efforts on driving enhanced operator performance with respect to the prevention of spills and improvements in compliance," he said.
Rutter, Statoil Canada, and the Government of Newfoundland and Labrador completed a collaborative research and development (R&D) project aimed at improving offshore oil and gas operations in harsh environments with ice conditions. Additions to Rutter's sigma S6 system resulted in the development of new remote sensing technology used in the automatic detection and tracking of ice. The system's ice analysis features are capable of providing automatic identification, outlining, and drift tracking of ice floes, pans, ridges, icebergs embedded in pack ice, and open water leads. "The technology that was developed has resulted in a large step forward in ice management capabilities," said Fraser Edison, Rutter's president and CEO. "The additions to the sigma S6 system will allow the automatic identification of ice characteristics leading to improved operational safety and efficiency for operations in ice-infested areas."

ABSTRACT Forward modeling of a Miocene prospect (Plum Point) from recently acquired long offset, 2D broadband seismic demonstrates evidence of multiple fluids phases within the Chidley Basin, offshore Labrador. The presence of liquid hydrocarbons in what has generally been thought of as a gas prone region has the potential to generate interest in a frontier, undrilled basin. This modeling contributes to the ongoing de-risking work in an unexplored basin where anomalous AVO signatures show potential prospects but where limited constraints on rock properties, due to lack of well data, create uncertainty in the interpretation of the seismic amplitude responses. This particular QI workflow moves through the generation of expected elastic and geologic properties of the Plum Point prospect using regional rock physics relationships, compaction trends and locally constrained data. The resulting expected properties are subsequently perturbed to best fit the pre-stack seismic response by incorporating empirical rock physics models as constraints to the perturbation analysis. This methodology allows for deterministic prediction of reservoir properties, represented in a detailed 2D seismic model.

Abstract Fog in northern climates and Arctic environs can be a risk to helicopter operations and shipping interests, as are high seas from severe storms that frequent these regions. Visibility conditions and forecasts determine whether helicopters can safely land on offshore facilities, or if personnel will need to be transferred by ship. High sea state conditions can affect offshore oil and gas exploration and production operations, including drilling, logistics, crane operations and emergency response. A workshop on Metocean Monitoring and Forecasting for the Newfoundland & Labrador Offshore, held 22-24 September 2014, identified the need of improving the visibility and severe sea state forecasting for Grand Banks which can have a positive contribution to safety and operations in the harsh North Atlantic Canada offshore environment. This has led to an open and collaborative multi-year Metocean Research and Development Project that is presently in its third year. Some twenty government, academic, and industry agencies are participating in this project. Detailed buoy and offshore installations-based scientific measurements have been collected over the past three years where previously there has been a lack of good quality observations. A climatology of low visibility (less than 1km) events shows a high frequency (about 55% of the time) during summer months. A "conceptual model" of Grand Banks fog has been developed, that defines the physical conditions under which fog develops, is maintained, moves and dissipates. The conceptual model will be the basis for the development of new visibility prediction systems which currently are not well established or verified. High seas, with wave heights over 6m, occur more frequently during winter. Sea state prediction systems are being evaluated for severe ocean wave conditions where they have reduced predictive skill. Currently, work is underway to establish the accuracy and consistency of several existing visibility and sea state prediction systems. This paper will illustrate results from the climatological studies and some of the unique metocean monitoring data being collected. The forecasting techniques (e.g. numerical atmospheric and oceanic prediction models, satellite-based schemes, and rules based systems) being evaluated, are outlined.

Abstract This paper presents an analysis of the dynamics of ice, current, and wind based on the data collected on land-fast ice and ice floes from the offshore environment of Newfoundland and Labrador during April-August 2015 using satellite-tracked beacons. The beacons were deployed in three sets of three as follows: fast ice beacons (FIB) 2, 3, and 5 were deployed in a triangular array on the land-fast ice offshore Makkovik; fast ice beacons (FIB) 1, 4, and 6 were deployed in a triangular array on the landfast ice offshore Nain, and ice floe beacons (IFB) 7590, 1590, and 0650 were deployed on drifting ice floes offshore Makkovik. Ten ocean drifter beacons were deployed on May 22, 2015 in open water in the vicinity of ice floe beacons 1590 and 0650 to study the characteristics of surface ocean current dynamics. The drift velocities of the two ice floes have been compared with the wind velocities measured by the two weather stations deployed on the ice floes. The buoy drift rose and exceedance probability plots have been presented to analyze the dynamical characteristics of first year ice and ice floes in the offshore Labrador ice environment.
Abstract In 2016 Nalcor Energy installed subsea cables across the Strait of Belle Isle, which comprises part of the Lower Churchill Transmission Project linking Muskrat Falls, Labrador, and Soldier's Pond, Newfoundland. The cable crossing site is southwest of a shoal which filters out deeper draft icebergs which could potentially contact and damage the cable. An initial study in 2011 was followed by iceberg tracking and current monitoring programs at the cable crossing site and a final study incorporating these data 2015-2016. This paper describes the application of a drift-based Monte Carlo model to assess iceberg risk to cables laid on the seabed in the Strait of Belle Isle. The model considers the effect of iceberg rolling which could potentially result in icebergs increasing draft and contacting cables laid on the seabed. Modeled iceberg drift was based on field observations, and measured and modeled currents. Based on results from the 2011 analysis it was decided to use directional drilling to route the initial portions of the cable from shore to break-put locations on the seabed in water depths in excess of 70 m. Rock dumping is used to stabilize the cables on the seabed at deeper water depths. Due to the extreme difficulties in trenching the very strong seabed or tunneling across the Strait of Belle Isle, the selected solution offers the most technically feasible and cost-effective solution for cable routing across the Strait of Belle Isle.
