ASIG‐Air Drop Test Report

BACKGROUND:
Fluid circulation was lost when drilling at Pirrit Hills. A possible explanation may be the fracture of the ice caused by dropping the core tube on to the fluid column several feet below the top of the drill rod. This testing will help to quantify the pressure that may have been created during the drop and possibly help to identify the cause of the circulation loss.

TEST OBJECTIVES:
Measure pressure in ASIG drill rod when core tube is dropped through air on to the drill fluid column in the drill rod. Drops should be performed with fluid at depths similar to those seen in the Pirrit Hills field season 2016‐17.
