Many Uses and quite normal26 Sep 2018 13:07
As the name implies, solid wire lines are a single strand of solid wire. It’s used in special circumstances, generally for running tests, placing valves, or dropping a pressure measurement device called a bomb. Some of the common tests and uses that may require a solid line include:
Temperature surveys. These are used to detect leaks in the tubing string. Gas will often escape through leaks and expand, causing a detectable drop in temperature. These surveys are usually run a regular basis, as frequently as every 6 months or as infrequently as once a year.
Pressure surveys. These are also run on a regular schedule, usually once a year. These surveys measure the pressure at the bottom of the hole. By comparing these readings to previous years’ measurements, the drop in reservoir pressure can be determined. This is useful information that can help to determine things like the amount of fluid remaining in the reservoir and gauging the effectiveness of pressure maintenance operations. It’s also possible to predict when a naturally flowing well will need to add artificial lift.
Directional surveys. When drilling a well, a direction survey may be run on a solid wire line. A clock is set within the survey bomb before it’s lowered into the hole. When the timer runs out, the bomb takes a 180 degree impression.
Other uses. Solid wire can be used to place valves, scrape paraffin and scale, and a few other specialized uses.
