Draw a labelled diagram to illustrate the extraction of natural gas.
State one method by which natural gas is transported in Pakistan.
In 2020 Pakistan had around 19 000 000 MMcf of gas reserves and gas use was 1 600 000 MMcf each year. MMcf = million cubic feet. Calculate the number of years for which Pakistan had gas reserves at the 2020 rate of consumption. Show your working.
