If you are a more established organization we are also available for short term work for quarterly or year-end reserves as needed.



Q. What economic evaluation software does your company use?

A. We use Aries by Landmark, but can use others if required for specific projects.

Q. Can you provide data for our evaluation?

A. We can make use of all the data available to the client and supplement it with data obtained from public sources. Publicly sourced data may include governmental completion and production data as well as data we purchase from IHS. We strive to obtain data in the most cost effective manner possible. 

Q. What do you charge?

A. Our rates depend on the type of work being done, whether it is for data gathering / engineering technician work or engineering work. It also depends on the amount of work needed. We have hourly and long-term daily rates. We also offer concierge engineering services in which the client has guaranteed on-demand services based on a prepaid monthly rate. The availability of concierge engineering services  are limited and begin with a minimum of one day per month.
