PART 3: PACKER TESTS

Packer tests are conducted to determine the hydraulic properties of sections of an uncased or open borehole. Packers are installed to seal off a test interval. Constant‑discharge or constant‑head tests are conducted to characterize hydraulic properties. Section 15 briefly describes packer‑test methods.
