Policies and Forms

The Core Research Center allows customers to sample rock material from the collection provided certain requirements are met. Please read our policies in advance of your appointment.

Know Before You Visit: Our Policies


Submit your list of cores or cuttings before your appointment. 

The list of requested cores or cuttings must be submitted by noon the day prior to the appointment. The list should be in priority order and must include the CRC library number, well name, and specific depths in feet you wish to view and/or sample. Before opening time on the scheduled day, the CRC staff will bring out as many of the requested wells as will fit in the allotted space.


No additional core or cuttings will be retrieved from the warehouse during the rest of that day. If a visit is scheduled on consecutive days, the CRC staff will bring out a different set of wells for each day. Please plan for the appropriate number of days.

 


We do not allow shipping cores off-site for workshops or displays.

In order to preserve the integrity of USGS Core Research Center cores, we do not allow shipping cores off-site for workshops or displays. Local (Denver metro area) shipping for non-destructive analysis and core slabbing will require Director approval. 

We offer free workshop space and associated support services, and we encourage our stakeholders to take advantage of this by hosting workshops at the CRC. This policy is intended to allow us to continue to provide you with the highest quality research and educational materials.

 


Workshops held at the CRC should primarily feature core from the CRC collection. 

Non-USGS core may be brought in for comparison, but it must be less than 25% of the total amount of core used for the workshop. The workshop sponsor assumes all responsibility for the privately-owned cores while at the CRC and in transit.
