Comparing carbon sequestration in an oil reservoir to sequestration in a brine formation-field study [PDF]

, 2008
Geologic sequestration of CO2 in an oil reservoir is generally considered a different class than sequestration in formations which contain only brine. In this paper, the significance and validity of this conceptualization is examined by comparing the ...

Reservoir quality evaluation of the Late Jurassic Manifa carbonate sequence in one of oilfield in the Persian Gulf [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2019
The late Tithonian Manifa carbonate is one of the important oil producing intervals in some oil fields of the Northwestern Persian Gulf. The combination of geological and petrophysical data in three key wells in one of oilfield, enabled us to clarify the

A Method of Productivity Prediction for Multi-Fractured Horizontal Well

Cejing jishu, 2023
The reservoir of horizontal wells in a block of Junggar basin is tight and highly heterogeneous. After large-scale volume fracturing by classification and clustering, there is a large difference in production.
