  1. Introduction

    1. Project Overview


This Agreement will govern the provision of Tubing Conveyed Perforating and associated equipment and services utilized onboard the Operator’s contracted Drilling Unit(s) offshore Newfoundland and Labrador.

Operator’s East Coast operations are managed from the local office and are supported using the established logistics infrastructure and resources in St John's, Newfoundland and Labrador.

The transport of personnel to and from St. John's and the Operating Area is conducted mainly through helicopter but, in isolated situations, supply boats may be used. The Operating Area, as defined in the Agreement, covers all of the Operator's land holdings off the East Coast of Canada.

Consistent with the legislative requirements of the Canada Newfoundland Atlantic Accord Implementation Acts, the Operator is committed to enhancing the business opportunities for Canada and Newfoundland and Labrador. Consequently, Contractor is encouraged to utilize the services of Newfoundland and Labrador and other Canadian companies and personnel wherever possible.


    1. Project Objectives


The long-term goals of the Operator are:

  • Execute a cost-effective program, while maintaining health, safety, quality and environmental responsibilities and meeting all due diligence requirements.

  • Minimize and phase capital expenditure.

  • Establish and maintain cost-effective relationships with suppliers and contractors, creating long term mutual benefits and a local infrastructure.

  • Effectively conduct core business activities.

  • Optimize synergy opportunities with other operators in the area.

  • Conduct operations with a moderate, cost effective, risk profile.

  • Develop synergies within product lines for completion services.
    1. Lead Service Supplier


Contractor has been selected as the lead service supplier for the scope of supply for Tubing Coveyed Perforating (TCP). The lead service supplier for the upper string completion contract is expected to oversee and co-ordinate the equipment supply, preparation, mobilization and running of all components for the upper string.
    1. Technical Risk and Program Time


Contract award included the consideration of equipment and service, technical specifications as well as completion program run time, risk and non-productive time. Any reduction in technical risk as well as any reduction in the completion program steps and/or time have been considered.
  1. General Conditions


This Agreement will include the provision of Tubing Conveyed Perforating (TCP) personnel, equipment, materials and services in relation to drilling, completions and intervention operations from the Drilling Unit.

  • The contractor shall provide replacement equipment as required if contracted equipment is not readily available for operations due to maintenance or any other reason not outside of operator’s control excluding redress or damage during transit to operating area.

  • Contractor shall be responsible to make themself fully aware of the Drilling Unit and local operating conditions and to specify any operational limits deemed necessary.

  • Contractor shall ensure that all Contractor’s equipment shall, on delivery, be accompanied by all appropriate current certification and maintenance records.

  • Contractor shall maintain a sufficient inventory of spares and consumables on board the Drilling Unit to ensure continued operation of all systems and ancillary equipment for seven days.

  • Contractor shall maintain locally 100 % back up of critical items for the well being completed and allow for sufficient operating spares and consumables as required to provide continuous operations.

  • Contractor shall store, preserve and maintain the materials and equipment until such time as they are mobilized.

  • Contractor shall be responsible for the assembly, testing and installation of Contractor’s equipment and materials at the work site.

  • The Operator shall notify the Contractor in writing in advance of the expected mobilization date.

  • Equipment is to be ready for mobilization to the rig for 1-May-2017. All equipment maintenance, assembly, testing and certification is the contractor’s responsibility and must be complete prior to mobilization.

  • Because of logistical and timing constraints of supplying items outside of the operating area preference will be given to optional or contingent equipment and supplies which will be on a call out basis and which will be situated in eastern Canada.

  • The Operator reserves the right to contract alternative “best in class” services to compliment services provided by the Contractor. The Contractor will make available the necessary data to facilitate integration of alternate services.

  • Contractor shall provide an offshore team of qualified, experienced personnel to ensure 24-hour operational and maintenance capabilities. Contractor shall also provide qualified relief personnel to work on a rotational basis as per the Operator’s preferred schedule. The anticipated preferred offshore rotation is 21 days.

  • Contractor shall provide crew list containing the names, roles and experience of each crew member before commencement of operations for company approval.

  • Contractor shall not change Contractor’s Personnel from their designated positions without prior written approval from the Operator as per MOC procedure outlined in the Drilling and Completions Operations Manual (available for review upon request).

  • Contractor shall identify any reduction in personnel requirements associated with the utilization of more than one of the services identified in this Agreement.

  • The Operator reserves the right to reject any Contractor’s Personnel that the Operator considers unsuitable. The Contractor must provide qualified replacements at no additional cost to the Operator.

  • Contractor, where providing equipment and services sourced from a third party, shall clearly indicate these items and state the name of the third party vendor.

  • During the term of this Agreement the Contractor is encouraged to submit alternative proposals or specifications, in addition to that required by the Operator, where Contractor considers that such an alternative would be a technical, commercial, economic or operational improvement over the Operator’s original specification. Such alternative proposals shall be clearly identified and clearly indicate and justify all technical, commercial, economic or operational benefits over the specification required by Operator.

  • The Contractor shall provide a detailed description of the equipment that is proposed under this Agreement. Any additional items that are not identified in the proposal, but are necessary for the Contractor to conduct the Services, shall be provided free of charge.

  • The Contractor is responsible for performing Design Qualification testing ( DQT) to ensure that any component not previously used under these or more strenuous conditions is fit for purpose. Contractor shall review proposed equipment and provide a list of components that require design qualification testing.

  1. Husky Atlantic Region Well Overview


The following sections will provide background information that may be used in determining the equipment and services that will be required to fulfill the obligations of this Agreement.
    1. Applicable Fields


This contract will extend over Husky’s expanding development and any potential exploration. The development areas include 3 significant extensions; the South White Rose Extension (SWRX), the North Amythest Extension and the West White Rose Extension (WWRX).

It is anticipated that these areas will be developed using four typical well types, though other designs may be possible in the future:



  • Horizontal Oil Production Wells

  • Deviated Gas Injection Wells

  • Deviated Water Injection Wells

  • Horizontal Water Injection Wells
    1. Completion Fluid Composition


The proposed completion fluid shall vary depending on well type: formate brine, filtered brine with oxygen scavenger, biocide, and corrosion inhibitors containing organic amines or inhibited diesel.
    1. H2S


Although the original concentration of H2S in the reservoirs is close to zero, with water injection wells are expected to sour. Because of this development wells are to be designed for 200 ppm H2S sour service. As such both carbon steel and 13 Chrome are suitable for Husky’s expected well conditions.
    1. Well Ratings


The following table represents the well ratings for the SWRX field as it has the highest rating for the White Rose development:
