Northstar Geoscience Consultancy provides expert geologic and geophysical consulting for prospect and acquisition evaluation, as well as operational and developmental geoscience services.  We have a core team of seasoned geologists and geophysicists that are available to review existing acreage, properties and assets and work in most of the current software to facilitate work on a client’s data and also to easily port our work into a client’s systems.


When moving into a new area of interest, whether in a province where your organization already has experience, or an area that may be frontier to you, Northstar can assist in identification and focusing areas of interest.  Our staff has modeled multiple North American basins and can either support/supplement your existing exploration team, or work independently to evaluate frontier areas that may be of interest.


When considering an investment or prioritizing opportunities, we provide ready access to seasoned professionals working with appropriate tools to integrate log and seismic data as well as direct measurement from cuttings and core.  Northstar can provide an objective view of opportunities that lie before you, and can illustrate additional value that may have been overlooked.   



Whether you are initiating a development drilling program, fine tuning a “manufacturing” operation or considering secondary recovery, Northstar can help to target drilling intervals, advise on spacing and focus completions.  

  • Time is of the essence – the cost of a position in a new play can escalate by a factor of ten in a matter of months.  We can support your existing staff that may be trying to manage operational responsibilities so new opportunities do not slip away.

  • Ramp up and down quickly.  Northstar has the personnel you need.  We can work in your office if desired for greater integration, or our offices if space and/or confidentiality is an issue.

Northstar gives you the advantage of a wide network of geoscience professionals and specialists built over the course of decades. Additional specialists may be available depending on scope of project.  Take a look at our featured consultants.
