Multilevel Drive-Point Piezometers consist of ports with stainless steel, 100 mesh cylindrical filter-screens in 3/4" OD stainless steel drive-point port bodies. The ports are connected using 3/4" NPT stainless couplings and 3/4" NPT steel drive pipe extensions. A Drive-Point Tip threads onto the first extension, or port, to be driven into the ...
Sand packs must be installed at the screen depths and seals in the borehole are constructed between the sand packs. Nested wells are different from well clusters in that the latter consists of a cluster of wells where tubes or pipes are constructed in separate, individual boreholes that are drilled and completed at different depths.
Driven wells may be very simply created in unconsolidated material with a well hole structure, which consists of a hardened drive point and a screen (perforated pipe). The point is simply hammered into the ground, usually with a tripod and driver, with pipe sections added as needed. A driver is a weighted pipe that slides over the pipe being ...
The lower pressure helps to increase the setting force on the packer. Used in a stimulation well. Rotation-set packer – Tubing rotation is used to set the packer to mechanically lock it in; a left-hand turn engages and a right-hand turn retrieves it. Hydraulic-set packers use fluid pressure to drive the cone behind the slips. Once set they ...
Gas lift well: gas is fed into valves installed in mandrels in the tubing strip. The hydrostatic head is lowered and the fluid is gas lifted to the surface. Single-well alternate completions: in this instance there is a well with two zones. In order to produce from both the zones are isolated with packers.
