Comparison of Asmari, Pabdeh and Gurpi formation's fractures, derived from image log

Journal of Petroleum Science and Engineering, 2009
Abstract Small scale fractures around the wellbore, strongly affect the hydrocarbon production. Identification of fracture plays a main role in production and development plans of oil fields. Image logs are one of the powerful tools in fracture study in wells. Image log is a high resolution “pseudo picture” of borehole wall.

Biozonation Paleobathymetry and paleoenvironmental study of the Gurpi Formation in southwestern Iran

2020
Planktonic foraminifera and major palynomorph groups (i.e. terrestrial, marine, and amorphous organic matter) of the Campanian-Selandian strata of the Gurpi Formation were studied to evaluate the changes in the Zagros paleobasin in southwestern Iran. Planktonic foraminifera were categorized into four morphotypes according to their paleodepth, extending

Calcareous nannofossils from the Gurpi Formation (Lower Santonian-Maastrichtian), faulted Zagros range, western Shiraz, Iran

Stratigraphy and Geological Correlation, 2010
The Gurpi section in western Shiraz, faulted Zagros range of southwestern Iran, contains one of the most complete Early Santonian to Late Maastrichtian sequences. The lack of a good fundamental paleontological study is a strong motivation for investigating calcareous nannofossils in southwestern Iran. The Gurpi Formation is mainly made up of grey shale.

Dinoflagellate and foraminiferal biostratigraphy of the Gurpi Formation (upper Santonian–upper Maastrichtian), Zagros Mountains, Iran

Cretaceous Research, 2006
Abstract A rich dinoflagellate cyst assemblage has been recovered from an outcrop of the Gurpi Formation, the hydrocarbon source rock in the South Iranian Basin. Key dinoflagellates recorded in the section studied provide a means of correlation with zonation schemes for Australasia and north-west Europe.

Depositional environment, sequence stratigraphy and biostratigraphy of the Gurpi formation in Fars zone, Zagros Basin (SW Iran)

Carbonates and Evaporites, 2020
To study the Gurpi Formation deposits in Fars area, 230 thin-sections which belong to Well No. 43 have been studied. The Gurpi Formation is 155 m in thickness. Lithology of the Gurpi Formation is mainly composed of thin to medium limestone, argillaceous limestone and shale. Lower boundary of the Gurpi Formation with the Ilam Formation is continuous and

Sedimentary and organic facies investigation of the Gurpi Formation (Campanian–Paleocene) in southwest of Zagros, Iran

Arabian Journal of Geosciences, 2013
The Gurpi Formation in the southwest of Iran has been studied for microfacies and bulk organic geochemistry in order to elucidate its depositional environment and petroleum source rock characteristics. The obtained results ended up with four types of organic facies and three types of microfacies through the formation.

Biostratigraphy of the Gurpi Formation (Santonian–Maastrictian) by using Globotruncanidae, Zagros Mountains, Iran

Carbonates and Evaporites, 2017
The study of Globotruncanids of the Gurpi Formation at Sepidar anticline in Zagros Mountains led to distinguishing Santonian to Late Maastrichtian biozones. Eight biozones were determined: biozone I (Dicarinella asymmetrica Zone) belongs to Santonian.
