SHELL AND CNPC WORK TOGEATHER TO AUTOMATE THE DRILLING PROCESS

摘要

As conventional oil and gas reserves become increasingly hard to find, the energy industry has shifted its focus to resources such as coalbed methane (CBM), shale and heavy oil. While these reservoirs contain vast hydrocarbon deposits, full development of each field requires the drilling of hundreds, if not thousands, of wells. Not surprisingly, drilling costs represent the biggest expense in exploitation of these reservoirs.
