Exploration Support Services

Graben Energy Nigeria Limited offers comprehensive exploration Support services to support oil and gas exploration and production activities. Our team of experienced geologists provides expert analysis and insights to help clients make informed decisions about their exploration and development strategies.

High Resolution Biostratigraphy

Graben Energy Nigeria Limited offers integrated high resolution biostratigraphy services with aggregate personnel experience of over 200 wells in the Cretaceous and Tertiary of the Niger delta, deep offshore Nigeria, Benin, Chad and Anambra basins. We utilize calcareous nannofossils, foraminifera, palynomorphs, well logs and sedimentological analyses in dating and defining stratigraphic sequences and systems.

Our biostratigraphy services include:

• Single-well analysis
• Multi-well analysis and correlation studies
• Well-site biostratigraphy
• Regional field studies and Basin Analysis
• Well-log Sequence Stratigraphy utilizing high resolution biostratigraphy based on planktonic marker fossils with lithologic and electric log data to identify systems tracts, Maximum Flooding surfaces, Sequence boundaries, etc which are correlated to a global chronostratigraphy framework

Sedimentology

Our range of sedimentological services aid clients in providing solutions to most exploration problems. Our experience in the Niger delta covers lithologic description, grain size analysis, calcimetry, heavy mineral analysis, petrography, x-ray diffraction analysis and scanning electron microscopy.

Our sedimentology services include:

• Single-well analysis
• Multi-well analysis
• Regional field studies
• Provenance
• Reservoir identification / diagenetic trends
• Porosity and paleoenvironmental prediction
• Sequence stratigraphy
• Core description including core fracture studies, integrated core and log displays, core photography and core slabbing

Sequence Stratigraphy

The predictive tool of Sequence Stratigraphy has revolutionized the concepts in sedimentology, stratigraphy and exploration geology, and saved the industry untold millions of dollars in pre-drill cost alone. Sequence Stratigraphy attempts to discern the migration of facies resulting from changes in a combination of factors, such as, sea-level, tectonics, climate and sediment influx.

The stratigraphic record is envisioned as a framework of repetitive packages of genetically related strata in which the loci of deposition of various sediment types can be anticipated. Thus, the predictive power of Sequence Stratigraphy has promoted it to an indispensable tool in modern exploration and production geology.

Graben Energy Nigeria Limited in collaboration with the world-renowned geoscientist Dr. Bilal U. Haq who pioneered the development of Sequence Stratigraphy, provided sequence stratigraphy trainings to the Nigerian Oil & Gas Industry in the early 2000s.
