Overview Background

Hydrocarbon exploration: the search for new reserves


Hydrocarbon exploration is an essential, but expensive, high-risk activity. It presents many unique challenges and risks that can incur millions of dollars of investment in capital and resources.

Historically, exploration has targeted oil and gas accumulations trapped in conventional high porosity reservoirs including sandstones and carbonates. In recent years, much more interest has been focused on searching for unconventional lower porosity resources such as shale gas shale oil, and coal bed methane. The search for new reserves has also led the industry to look deeper and also below geologically complex and seismically opaque features such as salt or basalt.

Exploration risk is a complex concept that is usually defined in conventional reservoir systems by assigning confidence to the presence and effectiveness of several key rock formations and critical processes. These include source, reservoir, seal, and overburden rocks, as well as hydrocarbon maturation, migration, accumulation, and preservation. In unconventional systems hydrocarbon migration is not necessary as the hydrocarbon is accessed directly from the source rock which also serves as the reservoir.
