Depositional facies and diagenetic control on reservoir quality of the Aptian Dariyan Formation, NW Persian Gulf

Marine and Petroleum Geology
The Aptian Dariyan (Shu'aiba) Formation is one of the major Cretaceous reservoirs in the Middle East. Despite its economic significance, an understanding of the influence of depositional facies and a sequence of diagenetic events on its reservoir quality

Identifying Gas-bearing Carbonate Reservoir Using Extended Elastic Impedance [PDF]

Iranian Journal of Oil & Gas Science and Technology, 2020
It is difficult to identify the carbonate reservoirs by using conventional seismic reflection data, especially in cases where the reflection coefficient of the gas-bearing zone is close to that of the carbonate background.

An approach for optimization of controllable drilling parameters for motorized bottom hole assembly in a specific formation

Results in Engineering, 2023
This study focuses on optimizing drilling parameters when using Positive Displacement Motors (PDMs). In drilling operations involving mud motors, weight-on-bit (WOB) alterations lead to variations in the system's parasitic pressure drop.
