Biostratigraphy

Biostratigraphy - Overview

Ellington Geological Services offers a comprehensive range of biostratigraphy services designed to support various stages of oil and gas exploration and development. The services include:

Wellsite biostratigraphy
Pre-drill biostratigraphy
Post-well biostratigraphy
Other services: “Hotshot”, Biosteering, and Legacy well

They utilize multidisciplinary approaches such as micropaleontology, nannopaleontology, and palynology to provide subsurface solutions across the oil and gas value chain. Their goal is to help clients reduce risks and uncertainties in complex decision-making processes by offering customized, fit-to-purpose, and cost-effective solutions.

Ellington Geological Services has global experience, with particular expertise in regions like North America (Gulf of Mexico and Canada Atlantic Margin), South America (Colombia, Venezuela, Trinidad, Guyana, and Suriname), North Sea, West Africa (Angola, Ivory Coast, and Ghana), Mediterranean Sea, and South China Sea. They have a proven track record of delivering high-quality, consistent, and efficient work to the oil and gas industry over the decades.

Wellsite Biostratigraphy

Ellington Geological Services provides essential wellsite biostratigraphy services aimed at improving drilling efficiency and minimizing costs. The services include:

Real-time stratigraphic monitoring
Reducing drilling surprises
Predicting stratigraphy ahead
Selecting casing points
Selecting coring points
TD (Total Depth) selection
Saving rig time costs
Cavings analysis

Wellsite biostratigraphy is a cost-effective method compared to other logging or drilling tools, offering unique advantages that other techniques may not.

Ellington Geological Services deploys multiple crews, including highly experienced biostratigraphers and technicians, to perform wellsite jobs and support drilling programs effectively.

Pre-drill Biostratigraphy

Ellington Geological Services offers specialized pre-drill biostratigraphy services to enhance well planning and mitigate risks. These services include:

Designing cost-effective biostrat analytical programs: Tailored to support the operational objectives of each well.
Customizing biostrat programs: Addressing unique technical challenges and HSE (Health, Safety, and Environment) risks to reduce uncertainties.
Reviewing existing biostrat data from offset wells: Leveraging historical data to inform current projects.
Building robust biostratigraphic models: Supporting real-time operational decisions.
Executing pilot projects: Developing high-resolution biostrat frameworks to enhance wellsite stratigraphic control.

These services are designed to provide customized solutions that address specific needs and challenges of each project.

Post-well Biostratigraphy

Ellington Geological Services offers key post-well services to enhance geological understanding and model accuracy. These include:

Infill micropaleontology, nannofossil, and palynology analyses: Providing comprehensive coverage of the drilled section and increasing resolution on key intervals.
Integrating wellsite biostratigraphy data: Updating regional and field models, including correlation with offset wells in IC (formerly ODM).

These services aim to improve the accuracy and reliability of geological models post-drilling.
