How does the foraminifera is important in oil exploration in parts of world and in pakistan?

Question

tell me the method by which the geologist use foraminifera for exploration of Petroleum.i have to make a report on it and i am not able to find relevant data on it.

how the geologists use the foraminifera for oil potential wells.what is the criteria behind this and how the geologists use them to identify that this area has petroleum.

Answer 1

The Foraminifera, or forams for short, are a large group of amoeboid protists with reticulating pseudopods, fine strands that branch and merge to form a dynamic net. They typically produce a shell, or test, which can have either one or multiple chambers, some becoming quite elaborate in structure. About 250,000 species are recognized, both living and fossil. They are usually less than 1 mm in size, but some are much larger, and the largest recorded specimen reached 19 cm.

The Foraminifera are closely related to the Cercozoa and Radiolaria, which also include amoeboids with complex shells; these three groups make up the Rhizaria. However, the exact relationships of the forams to the other groups and to one another are still not entirely clear.

Before more modern techniques became available, the oil industry relied heavily on microfossils such as forams to find potential oil deposits.

Answer 2

They use large THUMPER trucks with sound sensors over the area. the thumpers go through the center of the sound sensor field ,the reflections are recorded and analyzed very quickly while they are setup. It might be necessary to re thump it.
