Multiphase Linear Flow in Tight Oil Reservoirs
SPE Reservoir Evaluation & Engineering, 2016Summary The main objective of this work is to gain a general understanding of the performance of tight oil reservoirs during transient linear two-phase flow producing at constant flowing pressure. To achieve this, we provide a theoretical basis to explain the effect of different parameters on the behavior of solution-gas-drive ...

Fracability Evaluation Method for Tight Sandstone Oil Reservoirs
Natural Resources Research, 2021As typical low-permeability unconventional fossil resources, tight sandstone oil cannot be exploited economically without effective hydraulic fracturing. Fracability is a term commonly used as a decision indicator to select candidate layers for hydraulic fracturing in unconventional reservoirs.

3D Fracture Modeling: Application on Tight Oil Reservoir
3rd International Discrete Fracture Network Engineering Conference, 2022Abstract The Oued Mya Basin is one of the most oil-productive basins in Algeria. The wells’ productivity in these low permeability Ordovician reservoirs is attributed to the interconnected fracture networks. The faults and fractures characterization were carried out on two approaches.

Enhanced Oil Mechanism of WAG in Tight Reservoir
2021Tight reservoir needs new gas injection methods to delay gas channeling for the development of fractures, which result in early gas channeling in continuous gas injection. In this paper, the feasibility of CO2 flooding in tight reservoir core is analyzed, and the mechanism of water alternating CO2 for tight reservoir with fracture development is ...

EOR in Tight Oil Reservoirs through Wettability Alteration
SPE Annual Technical Conference and Exhibition, 2013AbstractIn fractured reservoirs, the efficiency of water flood is governed by spontaneous imbibition of water into oil-containing matrix blocks. When the matrix is oil-wet or mixed-wet, little oil can be recovered by imbibition. The objective of this work is to identify chemicals that can be added to the injection water that can induce imbibition into ...

Re-injecting Produced Water into Tight Oil Reservoirs
SPE Canadian Unconventional Resources Conference, 2012Abstract The technical challenges regarding re-injection of produced water into tight oil reservoirs are discussed based on commercial experience. This paper demonstrates a successful case study based on a project that launched in 2005. The objective was to treat 320 m3/day of produced wastewater for tight oil reservoir re-injection. The

Optimum Well Completion Strategies in Tight Oil Reservoirs
Offshore Technology Conference-Asia, 2014Hydraulic fracturing is currently the completion of choice in most tight reservoirs; however, the ultimate performance of fractured wells is severely affected by the interfering effects inside the fracture and inter fractures. Previous simulation studies investigated the effects of well spacing and fracture length on well productivity in low ...

High Efficient Imbibition Fracturing for Tight Oil Reservoir
SPE Trinidad and Tobago Section Energy Resources Conference, 2018Abstract In view of tight oil reservoirs with no natural productivity (tight sandstone and carbonate reservoirs with matrix permeability under overburden pressure of no more than 0.2mD (pore permeability less than 2mD)), a nanometer high efficient oil washing agent has been developed by combining nano-drop, high efficient oil washing ...

Multimodal reservoir porosity simulation: An application to a tight oil reservoir
Journal of Applied Geophysics, 2014Abstract At appraisal stage of a reservoir characterization, a key step is the inference of the reservoir static properties, such as porosity. In this study, we present a new nested workflow that optimally integrates 3D acoustic impedance and geophysical log data for the estimation of the spatial distribution of reservoir porosity, which is applied ...
