Abstract

A method includes making coiled tubing at a coiled tubing manufacturing unit coupled to a coiled tubing transportation system. One or more coiled tubing reels are transported from the coiled tubing manufacturing unit to one or more moveable well drilling systems using the coiled tubing transportation system. The coiled tubing transportation system runs from the tubing manufacturing unit to one or more movable well drilling systems, and then back to the coiled tubing manufacturing unit.

Claims

1-1250. -1250. (canceled)

1251. A method, comprising:

making coiled tubing at a coiled tubing manufacturing unit coupled to a coiled tubing transportation system; and

transporting one or more coiled tubing reels from the coiled tubing manufacturing unit to one or more moveable well drilling systems using the coiled tubing transportation system, wherein the coiled tubing transportation system runs from the tubing manufacturing unit to one or more movable well drilling systems, and then back to the coiled tubing manufacturing unit.

1252. The method of claim 1251, wherein making the coiled tubing comprises rolling plate metal to form tubing, welding the seam of the tubing, and coiling the coiled tubing on a reel.

1253. The method of claim 1251, wherein a reel of coiled tubing from the tubing manufacturing unit has a diameter of at least 15 m.

1254. The method of claim 1251, further comprising using at least some of the coiled tubing to drill and line a well to be drilled, or being drilled, by one or more of the movable well drilling systems.

1255. The method of claim 1251, further comprising providing utilities to one or more well drilling systems from one or more centralized utility units.

1256. The method of claim 1251, further comprising positioning one or more of the movable well drilling systems using a global positioning system.

1257. The method of claim 1251, further comprising a tracking system configured to actively assess locations of a position and/or state of one or more of the movable well drilling systems.

1258. The method of claim 1251, further comprising delivering coiled tubing reels from the coiled tubing manufacturing unit to the coiled tubing transportation system using one or more gantries.

1259. The method of claim 1251, further comprising returning empty reels from one or more of the drilling systems along the coiled tubing transportation system to the coiled tubing manufacturing unit.

1260. The method of claim 1251, further comprising drilling a subsurface heater wellbore using one or more of the well drilling systems.

1261. A method for making coiled tubing for a wellbore in a formation, comprising:

assessing properties of at least a first portion of a treatment area in the formation;

making coiled tubing at a coiled tubing manufacturing unit based on, at least in part, one or more of the assessed properties of the first portion of the treatment area, wherein the coiled tubing manufacturing site is coupled to the first portion of the treatment area with a coiled tubing transportation system;

transporting the coiled tubing from the coiled tubing manufacturing site to the first portion of the treatment area using a coiled tubing transportation system; and

drilling a first wellbore using a movable wellbore drilling system and the coiled tubing.

1262. The method of claim 1261, wherein the coiled tubing transportation system comprises one or more gantries.

1263. The method of claim 1261, wherein the coiled tubing transportation system comprises a looped path from the tube manufacturing unit to one or more wellbore drilling areas, and from one or more of the wellbore drilling systems to the coiled tubing manufacturing unit.

1264. The method of claim 1261, wherein at least one moveable drilling system comprises a gantry.

1265. The method of claim 1261, further comprising drilling a heater wellbore using one or more of the well drilling systems.

1266. The method of claim 1261, further comprising drilling a subsurface heater wellbore using one or more of the well drilling systems, and installing a heating system in the heater wellbore.

1267. A method for making coiled tubing and transporting such coiled tubing to a well, comprising:

drilling at least a portion of a first well in a treatment area;

assessing properties of the first well;

making a first coiled tubing at a coiled tubing manufacturing unit based on, at least in part, the assessed properties of the first well, wherein the coiled tubing manufacturing unit is coupled to the first well with a coiled tubing transportation system;

transporting the first coiled tubing from the coiled tubing manufacturing unit to the first well using the coiled tubing transportation system;

drilling at least a portion of a second well in the treatment area;

assessing properties of the second well;

making a second coiled tubing at the coiled tubing manufacturing unit based on, at least in part, the assessed properties of the second well, wherein the coiled tubing manufacturing unit is coupled to the second well with the coiled tubing transportation system; and

transporting the second coiled tubing from the coiled tubing manufacturing unit to the second well.

1268. The method of claim 1267, wherein the second coiled tubing comprises at least one property different from properties of the first coiled tubing.

1269. The method of claim 1267, wherein the coiled tubing transportation system comprises one or more gantries.

1270. The method of claim 1267, wherein the tubing transportation system comprises a loop from the coiled tubing manufacturing unit to one or more wellbore drilling areas, and from one or more wellbore drilling systems to the coiled tubing manufacturing unit.
