In the exploration of oil and gas, understanding "story" stored in rock is key to finding new energy resources.
One of the most effective scientific ways to read that geological story is through biostratigraphy — A branch of science that studies micro fossils to determine the age and environment of a layer of rock.
Behind this simple-looking process, biostratigraphy holds a vital role: determining when and how rock is formed, as well as whether the current condition allows the accumulation of hydrocarbons.
As a science lab with experience in the national and international energy industry, Indonesian Stémen Brick (BSILAB) is present to help the Migas company understand the history of the Earth through the approach of modern biostratiography precision and comprehensive.
Why Biostratigraphy is so important in exploration
Each layer of rock is a time archive that recorded environmental changes millions of years ago.
By analyzing microfossils like foraminifera, nannoplankton, and PolenWell, experts can tell:
- The age of relative layers of rock.
- Kind of a intercept environment.
- Potential reservoir or a cover layer ideal for accumulation of oil and gas.
This data is then integrated with the results of geochemistry, petrology, and core analysis to form a whole picture of geology.
Without an accurate understanding of biostratigraphy, exploration often faces risk misinterpretation.
Mistakes determine the age of the layer alone can make drilling miss up to hundreds of feet of the actual target.
Biostratigraphy service in BSILAB
BSILAB provides Routine Biostratigraphy Services and Wellsite Services to support the entire stage of exploration — from initial analysis to advanced stratiography interpretation.
1. Foraminifera analysis
Fossil foraminifera is a prime indicator in determining the age of sea rocks.
Through microscopic identification, BSILAB is able to map the age limit of formation and the change of environment detection over time.
2. Nannoplankton analysis
Nannoplankton is a very small marine microorganism sensitive to environmental change.
Nannoplankton analysis is used to determine a more detailed chrono limit, especially on a smooth sediment layer.
3. Palynology Analysis.
Palynology is used to analyze nonmarine rock or transition, like a delta or swamp environment.
This data helps understand paleoclimat and paleogeography in the past, which affects the formation of hydrocarbons.
Technology and Standard Lab
BSILAB implemented international laboratory standards with the system sample preview, prefix clean room, and microscopic analysis That fulfills protocol. RP 40 API and ISO / IEC 17025.
Each sample is analyzed by experienced experts who have handled a major exploration project in various parts of Indonesia. — from Sumatra to Papua.
Analytic data is presented in the form of a digital report complete with a diagram of biostratigraphy, range chart, and interpretations of stratigraphy to ease integration with such exploration software Petrel or Kingdom Suite.
Case Studies: Discovered Forgotten Potential Layers · Global Voices
In 2022, one of BSILAB's clients faced the challenge of determining a prospective zone in a California coastal area.
Logging results and geophysical data indicate a reference, but correlation between wells is inconsistent.
BSILAB team did. detailed biostratiography analysis using samples cuttings from some wells.
From the results of foraminifera and nannoplankton identification, it was discovered that one of the layers previously deemed insignificant turned out to be a young formation associated with the deltaic environment — An ideal environment for hydrocarbon trapping.
These findings encouraged clients to do additional drilling in the zone, and managed to find new reservoir layers with hydrocarbons higher than expected.
Here's the real proof that biostratigraphy not only reads the past, but also opens up the future.
Integrating with Other Geoscience Discipline
BSILAB excellence lies in its ability to integrate the results of biostratiography with other analyses:
- Geochemistry: Determines the relationship between the age of rock and the potential source of hydrocarbons.
- Ethology: Analyzing the type of rocks and environment of intercepts.
- Core Analysis: Verifying fossil data with the physical properties of rock.
This approach ensures the results of interpretation not only accurate, but also provides a thorough insight for the decision-making of exploration.
