[citation needed] Essentially, a MWD operator measures the trajectory of the hole as it is drilled (for example, data updates arrive and are processed every few seconds or faster). This information is then used to drill in a pre-planned direction into the formation which contains the oil, gas, water or condensate.
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 ...

The price of Brent crude, the global oil benchmark, rose more than 4% Friday to trade at nearly $90 a barrel. West Texas Intermediate crude oil futures, the US benchmark, jumped 4.2% to $86 a barrel.
Mud logging technicians in an oil field drilling operation determine positions of hydrocarbons with respect to depth, identify downhole lithology, monitor natural gas entering the drilling mud stream, and draw well logs for use by oil company geologist. Rock cuttings circulated to the surface in drilling mud are sampled and discussed.
"Oil is not going to be in short supply, so we keep more of a bearish stance on oil [in 2025]," Francisco Blanch, head of Bank of America's global commodities and derivatives research, said ...
In June 2021, the national average price for a gallon of gas was $3.09, according to data from AAA, but as of June 2022, it had topped $5. That marks a gain of over 60% in a single year.
Many modern oil and gas wells are drilled directionally. At first, loggers had to run their tools somehow attached to the drill pipe if the well was not vertical. Modern techniques now permit continuous information at the surface. This is known as logging while drilling (LWD) or measurement-while-drilling (MWD).
