Most of the greatest oil fields have been found as a result of successful exploration drilling near surface oil seeps, both onshore and offshore. However, this seemingly successful voyage has not been a straightforward story and history is littered with disastrous examples of where these Direct Hydrocarbon Indicators have been ignored by management, due to the prevailing wisdom (truths) and technical advice of their, so-called, “experts”. If we don’t learn these lessons from history, then we are doomed to repeat these expensive failures, re-drill costly wildcats or miss overlooked opportunities. We, as an industry, cannot afford to do this, especially in the current price environment.
The advancement (or otherwise) of geological thinking through time will be briefly reviewed, together with several published industry look backs, concluding with some important learnings from around the world, set with in a sequence stratigraphic context. Global eustatic sea level fluctuations are directly responsible for the distribution of some of the major reservoir prone intervals (especially in deep water settings) throughout the geological past and the resultant sand fairways are completely predictable. Examples of these will be demonstrated during the course of the presentation. The importance of repeated glacial loading and unloading (uplift) on the very recent redistribution of hydrocarbons of the NCS (and also UKCS) will also be touched upon and the exploration and economic implications of these observations briefly discussed.
