Soil Sampling

For over three decades, Pacific Drilling Co. has strived to provide accurate soil samples for clients located throughout the Southwestern United States. After all, it is the reason we exist. Our experienced personnel and all rigs are equipped to collect soil samples using auto hammers, safety hammers, and for extreme limited access, our own custom built donut hammers. Additionally, we now offer the revolutionary eSPT™ auto hammer from MARL Technologies. This electronic auto hammer meets every requirement of ASTM Standard 1586 for the Standard Penetration Test. It verifies the data digitally, calculates its energy efficiency, and transmits the results via the cloud to your desktop. Finally, non-operator dependent, repeatable and reliable SPT data, only from Pacific Drilling Co. Download the spec sheet here.
