Petroleum potential of the Chalbi basin, NW Kenya
Abstract This paper deals with the study of subsurface stratigraphy of the Chalbi rift basin, northwest Kenya. The basin is known to have evolved through extension tectonics that brought out continental rifting as a part of the major Gondwanaland breakup in the Late Paleozoic and continued in the Me...

| 520 | |a Abstract This paper deals with the study of subsurface stratigraphy of the Chalbi rift basin, northwest Kenya. The basin is known to have evolved through extension tectonics that brought out continental rifting as a part of the major Gondwanaland breakup in the Late Paleozoic and continued in the Mesozoic and Tertiary. This work has been based on gravity, seismic and gamma ray data, as well as the drill core logs available. The geophysical data used was collected by AMOCO as part of the hydrocarbon programme. But the gravity anomaly maps as well as seismic profiles were most useful for the interpretations incorporated in the present paper. They revealed the presence of several horst and graben structural systems. It was also revealed that the basin attracted sedimentary piles ranging up to 5 km thickness, which were deposited on basement rocks of Precambrian age. The basin subsequently got covered by basaltic flows of mainly Miocene age. The drill core lithologs that were available pertain to wells: C1, C2 and C3 in the Chalbi basin (Cretaceous). Comparing the lithologs from these wells with the seismic and gamma ray characteristics have been discussed in order to characterise the strata in which there was oil/gas shows. These characteristics were further seen in the light of the porosities, organic matter and other sedimentological parameters in order to understand the essential features of source rocks, reservoir rocks and the cap rocks. An attempt has been made to extrapolate the knowledge gained for recommending the probable prognostic sites for future drilling in the Chalbi Basin. | ||

The basin is known to have evolved through extension tectonics that brought out continental rifting as a part of the major Gondwanaland breakup in the Late Paleozoic and continued in the Mesozoic and Tertiary. This work has been based on gravity, seismic and gamma ray data, as well as the drill core logs available. The geophysical data used was collected by AMOCO as part of the hydrocarbon programme. But the gravity anomaly maps as well as seismic profiles were most useful for the interpretations incorporated in the present paper. They revealed the presence of several horst and graben structural systems. It was also revealed that the basin attracted sedimentary piles ranging up to 5 km thickness, which were deposited on basement rocks of Precambrian age. The basin subsequently got covered by basaltic flows of mainly Miocene age. The drill core lithologs that were available pertain to wells: C1, C2 and C3 in the Chalbi basin (Cretaceous). Comparing the lithologs from these wells with the seismic and gamma ray characteristics have been discussed in order to characterise the strata in which there was oil/gas shows. These characteristics were further seen in the light of the porosities, organic matter and other sedimentological parameters in order to understand the essential features of source rocks, reservoir rocks and the cap rocks. An attempt has been made to extrapolate the knowledge gained for recommending the probable prognostic sites for future drilling in the Chalbi Basin.

The basin is known to have evolved through extension tectonics that brought out continental rifting as a part of the major Gondwanaland breakup in the Late Paleozoic and continued in the Mesozoic and Tertiary. This work has been based on gravity, seismic and gamma ray data, as well as the drill core logs available. The geophysical data used was collected by AMOCO as part of the hydrocarbon programme. But the gravity anomaly maps as well as seismic profiles were most useful for the interpretations incorporated in the present paper. They revealed the presence of several horst and graben structural systems. It was also revealed that the basin attracted sedimentary piles ranging up to 5 km thickness, which were deposited on basement rocks of Precambrian age. The basin subsequently got covered by basaltic flows of mainly Miocene age. The drill core lithologs that were available pertain to wells: C1, C2 and C3 in the Chalbi basin (Cretaceous). Comparing the lithologs from these wells with the seismic and gamma ray characteristics have been discussed in order to characterise the strata in which there was oil/gas shows. These characteristics were further seen in the light of the porosities, organic matter and other sedimentological parameters in order to understand the essential features of source rocks, reservoir rocks and the cap rocks. An attempt has been made to extrapolate the knowledge gained for recommending the probable prognostic sites for future drilling in the Chalbi Basin.</subfield></datafield><datafield tag="650" ind1=" "

Petroleum potential of the Chalbi basin, NW Kenya |
| abstract |
Abstract This paper deals with the study of subsurface stratigraphy of the Chalbi rift basin, northwest Kenya. The basin is known to have evolved through extension tectonics that brought out continental rifting as a part of the major Gondwanaland breakup in the Late Paleozoic and continued in the Mesozoic and Tertiary. This work has been based on gravity, seismic and gamma ray data, as well as the drill core logs available. The geophysical data used was collected by AMOCO as part of the hydrocarbon programme. But the gravity anomaly maps as well as seismic profiles were most useful for the interpretations incorporated in the present paper. They revealed the presence of several horst and graben structural systems. It was also revealed that the basin attracted sedimentary piles ranging up to 5 km thickness, which were deposited on basement rocks of Precambrian age. The basin subsequently got covered by basaltic flows of mainly Miocene age. The drill core lithologs that were available pertain to wells: C1, C2 and C3 in the Chalbi basin (Cretaceous). Comparing the lithologs from these wells with the seismic and gamma ray characteristics have been discussed in order to characterise the strata in which there was oil/gas shows. These characteristics were further seen in the light of the porosities, organic matter and other sedimentological parameters in order to understand the essential features of source rocks, reservoir rocks and the cap rocks. An attempt has been made to extrapolate the knowledge gained for recommending the probable prognostic sites for future drilling in the Chalbi Basin. © Geological Society of India 2013 |
