Geochemical correlation of Asmari/Jahrum reservoir of Nargesi oilfield with seeps nearby

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2016
ABSTRACTIn case of maintaining the reservoir pressure by gas injection, connection between the reservoir and oil seeps around the oilfield should be investigated. Existence of probable conduits from reservoir to surface would cause problems such as environmental issues and capital losses.

New Mathematical Correlation for Diffusivity Coefficient and Geostatistical Relation of Asmari Reservoir

Proceedings, 2009
Diffusivity coefficient shows fluid ability flowing through porous media respect to wellbore storage coefficient. It can be used to identify reservoir characterizations which its value can be obtained from welltest analysis. A new mathematical correlation between productivity index (PI) and Diffusivity coefficient has been obtained which applying it ...

An Overview of Oil Well Drilling Problems in Shale Formations (Case Study: Asmari Reservoir)

Geosciences and Engineering, 2021
Shale layers are found in 75% of the drilled sections in Iran, which causes 90% of the problems of instability of wells, and this can cause a number of problems, such as complete or partial collapse of the well or even loss of the well before it reaches its goal.

Assessment of Fracture Density Distribution from Image Logs for Sensitivity Analysis in the Asmari Fractured Reservoir

EARTH SCIENCES AND HUMAN CONSTRUCTIONS, 2023
Characterizing fracture properties in naturally fractured reservoirs poses a significant challenge. While welltesting remains valuable, it often fails to provide precise descriptions of these properties. Bridging this gap requires the integration of geological expertise to enhance fracture assessment.

Patterns And Structural Positions of Productive Fractures In the Asmari Reservoirs, Southwest Iran

Journal of Canadian Petroleum Technology, 1994
Abstract In wrench faulted areas, similar to the one introduced here, identifying structural styles and their histories could be one of the most important tasks in studying tectonic related fractures and faults. The main purpose of this paper is to examine the patterns and structural positions of ...

Depositional and diagenetic impact on reservoir quality of the Asmari carbonate reservoir, Naft-Sefid Oilfield, SW Iran

2020
The Oligo-Miocene Asmari Formation with main carbonate and evaporate lithology is the most prolific reservoir in the Dezful Embayment, south-west of Iran. Depositional and diagenetic effects on reservoir quality in the sequence stratigraphic framework were carried out on the basis of petrographic investigation, petrophysical logs, and core measurement ...

Rock typing using geological and petrophysical data in the Asmari reservoir, Aghajari Oilfield, SW Iran

Journal of Petroleum Science and Engineering, 2017
Abstract The Oligo-Miocene Asmari Formation, which extends over the entire Zagros foreland basin, is one of the most important hydrocarbon reservoirs in the Middle East. The Aghajari Field is one of the largest oilfields in the Zagros basin with the Asmari Formation being the major reservoir rock.

The Effect of Tar on the Petrophysical Analysis of FMI in Asmari Fractured Reservoir

2015
Historically, in Iran, the borehole imaging tools as the FMI/FMS are acquired to locate major structural features, such as faults and fractures and sedimentary environment interpretation, and it has more advantages to the conventional methods for reservoir characterization.

The Khaviz Anticline: an outcrop analogue to giant fractured Asmari Formation reservoirs in SW Iran

Geological Society, London, Special Publications, 2007
Abstract The carbonate reservoirs in the Late Oligocene—Early Miocene Asmari Formation in the Dezful Embayment of SW Iran are characterized by low matrix permeability, and effective drainage is dependent on the occurrence of open fractures. Limited information on fracture orientation and fracture density is available from core and borehole ...

Case History: Seismic facies analysis based on 3D multiattribute volume classification in Shadegan Oilfield - Asmari Reservoir, Iran.

Proceedings of SPE/EAGE Reservoir Characterization and Simulation Conference, 2007
Abstract Shadegan oilfield is located in Khuzestan province in southwest of Dezful embayment, southwest of Iran. The latest 3D surface seismic was carried out in 1999 over an area of 192 km2 in this field to resolve structural ambiguities, delineate exact dimensions of the field, estimate reservoir parameters and perform a seismic facies
