New PDC bit designs include features that attempt to address common problems; however, these bits still have some shortcomings when drilling in extreme environments. Researchers are working to improve drill bit performance, and a reliable, thermally stable, polycrystalline (TSP) diamond bit is being developed.
Direct-push technology (DPT) ground water sampling equipment generally falls into one of two broad categories -- point-in-time ground water samplers, or DPT-installed ground water monitoring wells. Ideally, both DPT point-in-time and monitoring well ground water sampling equipment should be used together to maximize their effectiveness.

This month, I'd like to touch on some procedures and methods of grouting I've picked up over the years, but first, the reasons for grouting casing: The primary reason to grout casing is to seal the annular space between the casing and the hole …
Making a proper splice is crucial to a long-lasting, trouble-free installation. A good splice is watertight, has good electrical conductivity and is mechanically strong. There basically are two ways to make a splice - the tape method and the shrink-tube splice-kit method.
