Abstract Maintaining a stable borehole and optimizing drilling are still considered to be vital practice for the success of any hydrocarbon field development planning. The present study deliberates case on estimation pore pressure fracture gradient recently decommissioned Volve oil at North Sea. High resolution geophysical logs drilled through reservoir formation studied have been used estimate overburden, pressure, pressure. well-known Eaton’s method Matthews-Kelly’s tools were gradient,...
The Cambrian and Ordovician clastic reservoirs of the Oued Mya Basin exhibit significant vertical thickness extensive lateral continuity, despite being tight. These reservoir intervals have not been properly understood yet in terms in-situ stress distribution pore pressure behaviour. main objectives were to infer state draw implications for tight oil development based on geomechanical analyses. We interpreted breakouts from a cumulative 1485 m acoustic image logs NW-SE SHMax orientation...
We have characterized the petrophysical and geomechanical properties of Late Cretaceous Turonian Cenomanian carbonate reservoirs from southeast Constantine Basin, northern Algeria. In general, carbonates exhibit a wide range porosities (2%–15%) permeabilities (0.001–10 mD), whereas reservoir appears to be very tight (<6% porosity <0.1 mD permeability). Based on their storage hydraulic flow characteristics, these were classified into two distinct rock types (RRT): RRT-I is hosted by...
The prediction of total organic carbon (TOC) content using geophysical logs is one the key steps in shale reservoir characterization. Various empirical relations have previously been used for estimation TOC from well-logs; however, uncertainty quantification model often ignored while performing a deterministic framework. We introduce problem Bayesian setting with goal enhancing together prediction. To signify uncertainty, we draw random samples parameters posterior distribution by realizing...
In this study, we interpret the maximum horizontal stress (SHmax) azimuth from breakout positions of wellbore and attempt to constrain SHmax gradient based on interpreted width. A cumulative 110 m breakouts are deciphered within Ordovician Hamra Quartzite interval Oued Mya Basin a 138 acoustic image log. These ranked as “A-Quality” following World Stress Map ranking guidelines. We infer mean orientation N28°E ± 8°. Following frictional faulting mechanism polygon approach, measurement minimum...
Shale resource assessment involves a detailed characterization of organic and geomechanical parameters for better insights on the reservoir properties classifying areas economic yield. To assess Eocene Younger Cambay (YCS) Group Ankleshwar field, western India, feasible shale play, we have applied multistage screening methodology that combines an estimation richness, brittleness index (BI), analyses. The estimated thermal maturity average total-organic-carbon (TOC) contents are within range...
Cyclones are one of the most widely used gas-solid separators in circulating fluidized bed (CFB) systems. This paper focuses on numerical study flow a cyclone attached to CFB system. The objective was understand pattern order run setup problem free. previous works do not include critical parameter such as coefficient restitution which is responsible for swirling effect and increase efficiency. Reynolds stress model (RSM) obtain gas characteristics. resulting pressure fields verified by...
