Gas production technology is improving all the time.
A gas well once took a week or more to drill but that same job can now be done in a matter of days.
There are many factors to take into account drilling a gas well and so the time frames vary.
The below time-lapse video courtesy of Santos shows a well north of Wallumbilla in Queensland being completed in under 3 days.
Some are faster, some are slower.
In general, the development of a gas field is now a much more rapid and less intrusive process than it has ever been in the past and the technology
is continuing to evolve.
