|---|---|---|
| 0.3 | Data logger bottom | |
| 23.7 | 20-in casing shoe | K-55, buttress, 94 lb/ft, all joints tack welded |
| 29.0 | T10 | Thermistor 10 |
| 58.0 | Stinger bottom | 5.5-in drill pipe, six joints; string weight = 8500 lb |
| 64.0 | T9 | Thermistor 9 |
| 87.0 | T8 | Thermistor 8; looped cable between T9 and T8 so that only 23 m, instead of 35 m, remained between them; only had maximum outer diameter of 2.3 in through looped section; each end of loop tapered to prevent hangups; cable shortened by 24 m total to accommodate new well depth |
| 107.4 | 16-in casing shoe | K-55, buttress, 75 lb/ft, last three joints tack welded |
| 110.0 | T7 | Thermistor 7; looped cable between T8 and T7 so that only 23 m, instead of 35 m, remained between them; only had maximum outer diameter of 2.3 in through looped section; each end of loop tapered to prevent hangups; cable shortened by 24 m total to accommodate new well depth |
| 115.0 | T6 | Thermistor 6 |
| 120.0 | T5 | Thermistor 5 |
| 125.0 | T4 | Thermistor 4 |
| 130.0 | T3 | Thermistor 3 |
| 132.0 | T2 | Thermistor 2; during installation of data logger tool string into drill pipe, the cable grip grabbed the thermistor cable, but not the spectra cable; this resulted in the thermistor cable sliding up 3 m with respect to the spectra cable; therefore, spacing between T2 and T3 is only 2 m, instead of the 5 m originally planned |
| 137.0 | Osmotic sampler 2 top | |
| 142.0 | Osmotic sampler 2 bottom | Intake at bottom and pushed inside drill holes after cutting off portion of tube containing air |
| 142.5 | Osmotic sampler 1 top | |
| 147.5 | Osmotic sampler 1 bottom | Intake extends 22 m into screened area, 3 m above top of sinker bar; had problems attaching extension to coupling at bottom of osmotic fluid sampler; glued fitting while assuring that tube remained free to flow; while extension tube was vertical and prior to attachment to osmotic sampler 1 (laying horizontally), retention cap fell off bottom of extension tube and fluid dripped continuously |
| 149.0 | Weak point | Pull test rated to 4,000 and 56,000 lb |
| 149.0 | End of 10.75-in casing | K-55, buttress, 40.5 lb/ft |
| 149.0 | Beginning of 10.75-in screen | K-55, buttress, 40.5 lb/ft, screen wrapped, 312 holes/ft, 0.5-in diameter, wrapped with triangular wire with 0.008-in gap over 0.125-in standoff rods |
| 171.0 | Osmotic sampler 1 intake | Located 3 m above top of sinker bar |
| 174.0 | Top of sinker bar | |
| 176.0 | Bottom of sinker bar | 156 lb in air, 3-in outer diameter, 2-m long |
| 202.3 | End of 10.75-in screen | |
| 208.0 | 10.75-in shoe | Unable to run casing past ~227 m, so removed three joints to place at current depth |
| 257.0 | Top of fill | |
| 266.0 | Total depth |
