Mass and Energy Tradeoffs of Axial Penetration Devices on Lunar Soil Simulant
Axial penetration of the lunar surface was performed to collect soil samples with drive tubes and drill cores on the six successful Apollo missions. Although the pile-driving and drill...
In Situ Recovery of Water from Dormant Comet Cores & CI Carbonaceous Chondrites
Water and volatiles may be produced by drill holes into dormant comet cores or class CI or CM asteroids. This is modeled after in-situ mining as in the Frasch process sulfur mines of the...
The Transport and Fate of Drilling Muds
The disposal of drilling muds from offshore oil platforms is of concern because of the potential effects of pollution from these muds. Both drilling muds and fine-grained bottom sediments...

Dry Drilling and Coring Development for Unsaturated Zone Studies
Two areas of major difficulty associated with characterization of any unsaturated zone are the conventional drilling and coring processes used to acquire the samples. These processes are...
Dynamic Testing to Predict Static Performance of Drilled Shafts Results of FHWA Research
The paper describes the preliminary results of recent research sponsored by the FHWA on predicting by relatively economical dynamic methods, the static capacity and performance of drilled...

Targeted Public Outreach
The Minerals Management Service (MMS) has a public affairs program whose goal is to inform the public about the functions of the MMS. An overview of the program is discussed in this article....
Reassessing the 3-Mile State/Federal Boundary
The allocation of state versus federal authority offshore is critical in determining the complexion and pace of OCS oil and gas development. Yet, recurring drilling moratoria indicate...
An Offshore Borehole Mining Experiment: Its Operational and Environmental Implications
The Continental Shelf Division of the Marine Minerals Technology Center (MMTC), conducted a miniborehole mining experiment offshore Georgia in June 1990. A remote placer drill developed...
