Explorer Historical Highlights

By the time they are drilled, almost all exploratory ventures today will have been geotechnically, statistically and economically analyzed to estimate their ultimate recovery of oil or natural gas, or its EUR, and its present monetary value, or PV, given discovery. This process is generally known as “exploration risk analysis” and it evolved primarily as a response to an endemic problem: explorers were discovering less than half of the EURs they forecast for their investors.

An old joke used to be told in Israel: Why did Moses so unwittingly lead the Jewish people to the land of milk and honey and not to one of its petroleum-rich neighbors? Not anymore. In the last decade, giant gas fields have been discovered in the Eastern Mediterranean Sea offshore Israel, and offshore gas is rapidly becoming the main source of energy for power generation.

Looking at the ruins of the Parthenon today, perched high on the Acropolis of Athens, it is difficult to imagine that those pollution-tainted marbles were once the pinnacle of a civilization that gave us the principles of philosophy, mathematics, logic and democracy. Looking at the ruins of what is left today of Petroleos de Venezuela S.A., it is difficult to imagine that, like the Parthenon, it once stood proudly as Venezuela’s beacon of modernity.

The world is awash in oil at the moment, but with chronic underinvestment in exploration coupled with global energy demand steadily rising, the stage may be set for an oil price spike in the years to come, according to some analysts. Others, on the other hand, predict that improved production methods and project efficiency will go a long way toward meeting supply demands with existing reserves.

“When you think about the future of energy in the year 2025, seven years from now, I see ______?” This was one of the digital interactive questions asked at the Energy Transitions Forum in Amsterdam last month. The answers from a room of energy professionals were telling: diversity, renewables, energy, change, hybrid, oil, gas. The Forum addressed how companies and geoscientists can broaden their roles for energy transitions that can include a lower-carbon future.

Alongside 3-D seismic, long-reach horizontal drilling and the application of plate tectonics to exploration, sequence stratigraphy has been one of the greatest scientific advances within the petroleum geology industry of the last 50 years. Since it came to the wider attention of the industry in 1977, it has been embraced because the integration of time-significant surfaces with stratigraphic architecture provides great predictive insight at a variety of scales and extracts value from many data types.

Oil companies made huge cuts in their exploration budgets during the 2015-17 industry downturn, canceling or postponing up to $1 trillion overall in scheduled and planned projects. At the same time, success rates for international exploration dropped to 50-year lows. The outlook for future reserves has stumbled, if not tumbled.
