Case Study
AMC BOS™ achieves an average increase of 84.6% Rate of Penetration (ROP)
Location: Cobre Panama
Resource Company: AKD PANAMA CORP
Resource: Cu
Application: Mineral exploration
Objectives
Increase the rate of penetration being hampered by multiple issues.
Challenges
The company was facing granodiorite and andesite formations in alternating low, medium and high fractured rock levels along the perforations.
Other issues experienced included:
- Overall low penetration rates
- Premature tool wear
- High consumption of fluids additives
IMDEX Solution
AMC Borehole Optimisation System™ (BOS)
BOS is a proactive solution combating fluid losses and borehole instability, by delivering a measured amount of AMC BOS FIX™ at regular intervals to the bottom of the drill string and up the annulus.
The fluid reacts instantly with borehole fluids, permeating and sealing fractures, providing a thin but robust lubristic membrane to the borehole wall.
IMDEX recommended the client use the AMC BOS solution in a preventive manner to maximise the probability of successful drilling and to reach the programmed bottom more efficiently.
Strategy & Solution
AMC BOS FIX™ polymer applied directly into the well through the AMC BOS UNIT™ tool, reacting immediately with the drilling fluid in the hole to form a highly lubricating polymer film which lines the walls of the borehole, consolidating the fractured formation to prevent the occurrence of landslides.
