In a Typical Field, 15% of the wells produce 50% of reserves.
In a Typical Basin, 15% of the fields contain 85% of reserves.
Our Sweetspot Analysis figures out why and finds you more reserves.
The U.S. Gulf Coast Basin makes a good example of a basin characterized by a Sweetspot reserves distribution. The block diagram offers a cut-away view of the Gulf of Mexico from Alabama to Texas. The view is to the northwest, and shows basement crustal distribution, known hydrocarbon reserves distribution and sediment fill geometry.
Assessing exploration or development risk accurately in a basin like the Gulf of Mexico requires us to understand geologic controls on hydrocarbon charge, traps, reservoirs, and seals. Hydrocarbon charge is not uniformly distributed in this basin. In fact, understanding hydrocarbon charge makes a bigger statistical contribution to reducing exploration risk than do sand conditions in the offshore Gulf of Mexico.
Successful oil and gas plays go through a life cycle. This cycle starts with initial observations and concepts. It continues with a period of testing and adjustment, and peaks at a level of high success rates and good predictive power for the exploration rules learned in the earlier stages. As a limited resource, most of the reserves which can be found with the working concepts and tools are eventually found. A long period of decreasing exploration effectiveness follows.
For large plays, this life history can span two or three generations. The economic pitfall that catches the most companies comes at the end of the cycle, when previously successful concepts and tools are applied past the point of diminishing return.
Geologic questions can be answered with greater speed and accuracy when several seismic attributes are displayed together. This example display uses Reflection Strength and Frequency to make a first- pass facies classification, which can then be used with traditional seis-strat and well data to predict depositional environments and reservoir conditions.
Multi-attribute seismic displays give us new freedom and flexibility in finding statigraphic information in seismic data. By using seismic attributes they allow automated classification and prediction of depositional environments. In regions where "ground-truth" responses are established this method gives us the picure of reservoir geometry we need to lower exploration risk. It does this with the added benefits of cost and time savings plus predictive accuracy. All this leads to better insight into the geology that makes a prospect succeed.
