The terms measurement while drilling (MWD), and logging while drilling (LWD) are not used consistently throughout the industry. Although these terms are related, within the context of this section, the term measurement while drilling refers to directional-drilling measurements, e.g. for decision support for the wellbore path, (Inclination and ...
Logging while drilling (LWD) is a technique of conveying well logging tools into the well borehole downhole as part of the bottom hole assembly (BHA).. Although the terms Measurement while drilling (MWD) and LWD are related, within the context of this section, the term MWD refers to directional-drilling measurements, e.g., for decision support for the smooth operation of the drilling, while ...

Gamma radiation is usually recorded in API units, a measurement originated by the petroleum industry. Gamma rays attenuate according to the diameter of the borehole mainly because of the properties of the fluid filling the borehole, but because gamma logs are generally used in a qualitative way, amplitude corrections are usually not necessary.
They are generally programmed by the measurement while drilling (MWD) engineer or directional driller who transmits commands using surface equipment (typically using either pressure fluctuations in the mud column or variations in the drill string rotation) which the tool responds to, and gradually steers into the desired direction.
The Metropolitan Water District, which delivers imported water to Southern California, is raising rates and property taxes to cover rising costs.
PTW – permit to work; PU – pick-up (tubing, rods, power swivel, etc.) PUD – proved undeveloped reserves; PUN – puncher log; PUR – plant upset report; PUQ – production utilities quarters (platform) PUWER – Provision and Use of Work Equipment Regulations 1998; PV – plastic viscosity; PVDF – polyvinylidene fluoride
Gomberg said the MWD needs to “reevaluate its business model.” He pointed out that the district is a wholesaler of imported water, and the vast majority of its revenue comes from selling water.
