FLUTe methods for underground measurements of many kinds
have gained acceptance as superior or complementary,
to traditional methods

FLUTe everting liners can:

• Provide a continuous seal of a borehole or pipe, and prevent migration of formation fluids through the open hole. No sealing grouts or bentonite seals are needed.

• Carry many useful devices such as tubing, instruments, absorbers, reactive covers, etc.. into place in the borehole while maintaining a continuous seal of the borehole.

• Map borehole transmissivity while displacing the borehole water.

• Support the borehole wall against collapse.

• Propagate through tortuous passages of varying diameters inaccessible to rigid piping or push rods.

• Tow geophysical sondes of many kinds along the interior of the borehole while supporting the borehole against collapse onto the sonde.

Be removed by inversion without the liner touching any other portion of the borehole wall.

Be fabricated in many different diameters and materials for many applications.
