As a part of our implementing our mission, we have conducted and facilitated studies, presentations and other documents on the topic of Enhanced Oil Recovery (EOR). These documents are broken into subcategories to help you find the information pertinent to each topic. 


Effective EOR decision strategies with limited data: Field cases demonstration
 1.09 MB

Enhanced-Oil Recovery (EOR) for asset acquisition or rejuvenation involves intertwined decisions. In this sense, EOR operations are tied to a perception of high investments that demand EOR workflows with screening procedures, simulation and detailed economic evaluations. Procedures have been developed over the years to execute EOR evaluation workflows.

Flue-Gas carbon capture on Carbonaceous Sorbents: Toward a Low-Cost Multifunctional carbon filter for "Green" energy producers
 185.4 KB

This work is motivated by the need for inexpensive carboncapture technology for combustion-based power plants. Such power plants produce electricity by converting coal or natural gas to carbon dioxide (CO2), which is normally vented as an 11%-12% component of flue gas that contains a balance of nitrogen and other minor components. Separating CO2 from such a flue-gas mixture poses no special technical problems for the known absorption, pressure-swing adsorption (PSA), and membrane technologies. However, these technologies have a tendency to be expensive for two principal reasons: the hot flue gas is produced at low pressure and the separated component (CO2) is highly dilute with an inert component (nitrogen).

Osage Oil Field Single-Well Chemical Tracer Test Shows Promise
 103.07 KB

The first-ever collaborative field demonstration project conducted by Osage Partners LLC, TIORCO, Chemical Tracers Inc., and the Enhanced Oil Recovery Institute (EORI) was completed in the Bradley Unit of the Osage oil field in October. The purpose of this project was to collect an in situ measurement of residual oil saturation from the reservoir. The single-well chemical tracer test also evaluated the effectiveness of an alkali-surfactant-polymer (ASP) to mobilize stranded oil.

Simulation evaluation of CO2 flooding in the muddy reservoir
 1.05 MB

The simulation evaluation concluded that gravity stable CO2 flooding can be an effective EOR method for the Grieve Muddy reservoir. Up to 23 MMBO could ultimately be recovered by gravity stable CO2 flooding. The reservoir has potential to sequester more than 145 BSCF of CO2 at the end of CO2 flooding operation. Prior to the simulation of history matching and CO2 flooding, a four-layer Petrel model of Grieve Muddy reservoir was developed based on the identified facies in the Muddy channel sand and the overlain sandstone interval of bay-head delta deposition. Porosity and permeability distributions of layers generated in the Petrel model were exported to the simulation model. An OOIP estimation of 67 MMBO in Grieve Muddy channel sand has resulted from a simulation history matching based on the full-field material balance. History matching also reveals that about one MMSTBO of oil and 8.2 BSCF of gas have moved down from the overlain low-permeability sandstone interval into the Muddy channel sand interval during the reservoir depletion.

Simulation evaluation of gravity stable CO2 flooding in the Muddy reservoir at Grieve Field, Wyoming
 3.19 MB

Grieve oil field was discovered in August 1954. The field is located in southeastern Wind River Basin, central Wyoming, and is currently operated by Elk Petroleum Inc. (Elk Petroleum), Figure 1. The producing oil reservoir is a stratigraphic/structural trap at a depth of 6,900 ft in the Lower Cretaceous, valley-fill and channelized, Muddy sandstone. The average structural dip in the Grieve area is about 15 degrees to the northeast.
