Salt Cavern Information Made Available on Web

Salt caverns have been used for decades to store various hydrocarbon products (for example, the Strategic Petroleum Reserve facility in Louisiana). Salt caverns are also used for waste disposal. In recent years nine facilities have been permitted to dispose of non-hazardous oil field wastes. It is known that others are planned.

In the 1990s Argonne National Laboratory studied and prepared a number of reports on salt deposits and caverns and the use of those caverns to dispose of non-hazardous waste materials from oil and gas operations. In 1999 Argonne received funding from the DOE to develop and organize this information into a salt cavern website hosted on a DOE website. Recent organizational changes led to this material not being available online. Information has now been reorganized and added to the Argonne web site at http://
web.ead.anl.gov/saltcaverns/
.

The site is organized into several sections including an overview of salt caverns, the geographical distribution of salt deposits in the U.S., a description of cavern siting and design criteria, the various uses for salt caverns, studies funded by the DOE and links to web sites containing useful information on salt caverns and related topics.
 

MMS 2006 SAFE
Award Winners

Winners of the Minerals Management Service’s (MMS) 2006 Safety Awards for Excellence (SAFE) are:

  • High OCS Activity: Newfield Exploration Company
  • Moderate OCS Activity: Nexen Petroleum USA, Inc.
  • Drilling Contractor: TODCO
  • Production Contractor: Baker Energy

Begun in 1983, the SAFE program is designed to elevate the awareness of safety and pollution prevention, encourage voluntary compliance, provide the public with better understanding of the professionalism of the Outer Continental Shelf operators, encourage excellence in safety and pollution prevention and to demonstrate that safe practices enhance protection of personnel.

2005 Safety Statistics for the Well Service Industry

The Association of Energy Service Companies (AESC) recently reported 2005 safety statistics. Even with the explosive growth in activity, key measures (below) showed improvement versus 2004 data. Data are from 51 companies reporting their safety statistics. The experience range most prone to injuries (both work experience on rig when injured and job position experience when injured) is in the 1-5 years range.

LTIR (Lost Time Incident Rate): 2.25, which is a 16.7 percent decrease from 2004

TRIR (Total Recordable Incident Rate): 3.63, which is an 8.2% decrease from 2004

5-Year Study Reveals Improving Pipeline
Spill Stats

Pipeline spills have declined steadily in the period from 1999 to 2004, both in number of spills and average spill volumes. The statistics are gathered by the Pipeline Performance Tracking System, a voluntary performance tracking initiative that began in 1999. Industry participants representing 85% of the transported crude, refined products and highly volatile liquids (HVL) report details on any offshore spill and any onshore spill greater than 5 gallons.

Individual spill information is confidential, but the aggregate statistics are reported annually. Some of the highlights of the most recent report include:

  • Over the 5 year period, the number of releases declined from 650 to less than 400, while the average volume declined from 130 bbl to less than 80.
  • Facilities spills (pumps, metering stations, storage) are still the most numerous at around 190, but showed a 35% reduction in the last two years due to increased awareness and emphasis on risk management.
  • The reduction in facilities failures is due primarily to a sharp decline in equipment or non-pipe failures.
  • Corrosion, once the leading cause of onshore pipeline failure, has declined from 130 incidents to 40, while third party damage and other causes remained relatively flat.
  • The number of small spills (less than 5 gallons) has declined by 50% over the 5-year period, while larger spills have declined only slightly.
  • Crude oil spills show the steepest decline over the period, refined products somewhat less and spills of HVLs are relatively flat
