Abstract The objectives of this study are listed as follows: (1) to calibrate the Inflow Performance Relationship (IPR) model for fractured horizontal wells under production conditions in the Wolfcamp A formation and to propose a new set of calibration coefficients for the target reservoir; (2...

... section of ∼68 MMBO. This can be observed through historical well results with low recovery factors and EUR’s of ∼40 MBO per 1000’. To unlock the true potential of this reservoir, BlackBrush began a 3-year study to design and implement an enhanced oil recovery ("EOR") project via a Huff n’ Puff ("HnP...

...&A) in 2010. Albeit heavily-depleted after a two-decade-long primary-recovery period through 13 "old fashioned" vertical wells, the reservoir still has commercially-viable, "easy oil" secondary-recovery prospects via a meticulously-optimized low-footprint waterflood program, ensuring minimal environmental...

... Abstract Gas and downhole water sink assisted gravity drainage (GDWS-AGD) is a promising gas-based enhanced oil recovery (EOR) process applicable for reservoirs associated with infinite aquifers. However, it can be costly to implement because it typically involves the drilling of multiple...

The recommended practice is an integration of data sets and analysis that yield the maximum injection pressure to maintain the well and formation integrity with different risk tolerance levels. upstream oil & gas water management produced water discharge enhanced recovery reservoir surface pressure...

... We built a compositional sector model for representing the interwell interference identified in an actual area of the Eagle Ford shale reservoir with updated available five-year production data (oil, gas, water flow rates and BHP). Similarly, this sector model was used to design EOR Huff-Puff...

... Abstract Due to complex characteristics of shale reservoirs, data-driven techniques offer fast and practical solutions in optimization and better management of shale assets. Developments in data-driven techniques enable robust analysis of not only the primary depletion mechanisms, but also...

... Abstract The effectiveness of secondary and tertiary recovery projects depends heavily on the operator's understanding of the fluid flow characteristics within the reservoir. 3D geo-cellular models and finite element/difference-based simulators may be used to investigate reservoir dynamics...

... employing big data and machine learning to explore the existed production data and geology information to screen the sweet spot from geology point of view. However, current recovery factor of most unconventional reservoirs is still very low (4~10%). A quick production rate decline pushes US operator...

... Abstract Unconventional oil reservoirs such as the Eagle Ford have had tremendous success over the last decade, but challenges remain as flow rates drop quickly and recovery factors are low; thus, enhanced oil recovery methods are needed to increase recovery. Interest in cyclic gas injection...

Especially in HTHS carbonate reservoirs, chemical EOR pilot tests were performed one after another ( Amrie, et al., 2015 ; Levitt, et. al., 2016 ). Nevertheless, in the case of high temperature, high salinity marginal...

The tight oil reservoir in this study has a high heterogeneity and other characteristics, including poor physical property, multi-layer development in the longitudinal direction, strong plasticity and strong sensitivity. The porosity is 5%-12% and the average permeability is 0.1 mD. There are 2-4...
