Drilling efficiency is the one lever operators actually control
Hydrocarbon production is a highly complex business – from geological probability of success averaging only ~32% globally to challenging drilling conditions and reservoir depths. Most factors are outside operators' control. What producers can influence is drilling efficiency – and this is where Saudi Arabia stands out globally.
