consists of a camp station, tanks, compressors, brine- treatment facilities, 

 burn pit, brine-disposal line, separators, and precipitators. The other 

 production facilities are located on pass banks and are mainly separators, 

 storage tanks, and various sorts of treatment equipment. The largest produc- 

 tion site is the Texaco terminal where ocean-going ships load crude oil produced 

 on the refuge. This site is approximately 11 ha (28 acres) and contains tanks 

 with a storage capacity of over 128 million liters (800,000 barrels). The 

 site was made from spoil pumped from the docking basin onto pass bank and 

 adjacent marsh areas. 



Many wells in the Delta Duck field have treatment devices associated with 

 them. These are usually line heaters that heat the materials in the flowlines 

 and prevent blockage from hydrate formation. The heaters are located on 

 separate pile formations and are connected to the wellhead by tubing. 



There are two burn pits located on the pass bank. Each is surrounded by 

 ring levees and contains smaller pits subdivided within. After the oil is 

 burned off, the brine is placed directly into a canal where it is dispersed by 

 the flow of water. 



There is constant activity concerning production on this area. Wells are 

 checked daily. Consequently, there is significant boat traffic in the area 

 that adds to siltation problems and disturbance factors. 



The Chevron operation consists of one production site located on the 

 banks of Romere Pass. This site has tank batteries, compressors, separators, 

 treaters, pumps, brine-holding facilities, and formerly, a saltwater disposal 

 well all at one location. The equipment is on a wide pass bank surrounded by 

 a levee. There are sublevees within the first levee, and all operations are 

 monitored from this site. After hurricane Camille, Chevron rebuilt the produc- 

 tion site to withstand hurricanes. Thus, operations buildings are raised 

 approximately 6 m (20 ft) above water level. 



Brine is cleaned by passing it through a series of settling and separation 

 pits. It is disposed of by placing it directly into the pass with water 

 flowing into the gulf. The brine disposal at this site comes from wells not 

 only on the refuge but also offshore, since this production site is also used 

 to treat petroleum produced in the gulf. The Chevron field also has continuous 

 operation associated with production. Wells are checked every day, and normal 

 production operations such as cleanout, workover, and maintenance continue. 



Installation and maintenance of lines. There are several hundred flow- 

 lines crisscrossing the Delta Refuge, leading from wells to production sites. 

 Most have been placed on the pass bank and marsh surface except where they 

 cross canals. Older flowlines came to the edge of the spoil or pass bank and 

 were bent sharply to pass beneath the canal. When canal banks have eroded.
