Ross Subsurface services

Ross Subsurface delivers services within Exploration, Reservoir Management, Production Technology and Acquisition and Divestment activities.The Subsurface team has particularly long experience from early phase license and field evaluations; e.g. license round assessments, drainage strategy, well concept selection and production philosophy.  

Services and Products

The Subsurface services can be offered as push-the-button products (predefined products and services for efficient delivery) or tailored made services for each product and according to the requirements from each of our clients.

Push-The-Button products

The Subsurface department has a number of pre-defined studies and reports.

Effective, Start-up-Ready Projects

These evaluations are efficient deliveries, where our team is drilled in the execution and evaluation methods. The projects are offered to fixed prices and execution time, ensuring security ensuring security on cost/delivery time. A short introduction to our Push-The-Button projects are defined below. 

License Application input

Input to the license applications in accordance with standards defined by NPD.

  • Reservoir and Field Development input (1-2 months delivery)
    A report covering the topics in chapters 2.3 and 2.4 of a license application. The report includes hydrocarbon potential and recovery profiles, development solution, cost estimation and economical figures. Eclipse simulation could be included. Based on general are experience and input from client.
  • HSEQ evaluations (1 month delivery)
    A report prepared by the Ross Offshore HSEQ center, covering the health, security and environmental assessments in a license application (chapter 5) 

Exploration products

  • Analytical regional HC-potential (1 month delivery)
    An analytical review of available history and information to determine the the source and migration history of a region. The analytical approach includes technical understanding of input sources and uncertainties, to get an overall understanding of the regions HC-potential.
  • Play model illustrations (2 weeks delivery)
    A 3D model of the palegeological environment / play model for a prospect, based on interpreted data. Essential information to increase the understanding of the prospect, to ensure a good understanding in exploration team and decision makers. The model can be used as input for illustration in license application. 

Value Protection services

In a time with low oil price and marginal economy in all projects, it is important to protect your values, verify that what you or the operator is doing is optimal or to get a new set of eyes to come up with new projects.

  • Field/Production optimization (1 month delivery)
    Bring a new set of eyes to see if there are overlooked opportunities for a field's present and future production strategy. The Ross Subsurface team will review the production and plans from a field, for a verification of the production strategy and to come up with alternative options to increase production.
  • Portfolio review (1-2 month delivery)
    A review of a set of our client's assets to suggest prioritizing of the various field's technical and time critical aspects. The input can be used for internal prioritizing of work or as input on how to challenge the operator in partner discussions. 
  • Decision Gate QC (2 weeks delivery)
    A quick review of DG-reports with the main focus to define possible project risks, but also to verify the technical work.
  • Due Diligence review (2 weeks delivery)
    There are typically large values at risk in Due Diligence processes. It is worth having a 3rd party review of the essential assessments to bring more certainty to the decisions.

The Ross Exploration team consists of geoscientists with experience from all areas of the Norwegian Continental Shelf.

Lisence evaluations/applications

Ross Exploration Team has experience from the previous license rounds with all from pre-screening of  APA-licenses, area evaluation of central area in Barents Sea, farm-in screening and evaluations, and having the full responsibility of a license application. License evaluations includes prospect evaluations, with volume uncertainty analysis. 

Exploration Strategy Advisory

Advisory on Exploration Strategy, procedures of license application, government communication.

Regional mapping

Mapping of larger areas, connecting areas and licenses together for a better understanding of area. Correlating seismic data, well log data and depth conversions.

Independent Business Development projects

Ross Offshore can run larger projects, evaluating multiple regions for prospectivity, drainage solutions, farm-in possibilities and development strategy. This work will require multidisciplinary effort from explorationists, reservoir engineers, production technology and will also benefit from Ross Offshore's partners on development solutions and cost evaluations. The work can both be related to upcoming license applications but also to possible M&A (merger and acquisitions) activities. 

Exploration 3D Geological illustrations of Plays

Ross Offshore has developed a new way of visualizing paleogeological environments, using 3D-gaming platforms. Illustrations can be used as part of the creative process in the Exploration work, as a tool to visualize prospect ideas for internal/external decision makers, and directly as illustrations in applications.

Seal/fault evaluations

Evaluation of the sealing of faults and cap rocks, to understand the potential for HC leakage.

Analytical HC potential evaluation (source, migration)

Evaluation of available information on both source maturity and migration possibilities, to evaluate the Hydrocarbon potential of an area. Our understanding is that it is important to get and overview of the HC potential of an area in the early phase of the exploration work.
