Evaluating the effectiveness of products and/or methods that might improve oil and gas production in Wyoming is one of the functions of the Enhanced Oil Recovery Institute (EORI). As part of that effort, EORI sponsored an evaluation of a novel product that reportedly could help reduce the detrimental effects of paraffin precipitation and deposition in oil wells.

This novel product is produced from recycled tires and is under development by a clean-tech company that converts scrap rubber materials into several beneficial products. Although analyses have shown that this product in its current form does contain a significant quantity of aromatic solvents that may act either as inhibitors of paraffin wax deposition or as a paraffin solvent, tests using the novel, tire-recycled oil (TRO) product on three different paraffinic oils from Wyoming oil fields showed that the concentrations of these solvents in the product are insufficient to provide substantial benefits for that purpose.

Advanced Resources International has published the U.S. CO2 Enhanced Oil Recovery Survey for end-of-year 2020.

The Enhanced Oil Recovery Institute’s Acting Director, Lon Whitman, is a contributor to an important and anticipated publication of the U.S. CO2 Enhanced Oil Recovery Survey.

The purpose of this updated survey is to provide a comprehensive status report of the 142 active CO2-EOR projects in the U.S., including enhanced production totals, reservoir characteristics, and other project parameters.

Throughout a challenging year, incremental oil production from CO2-EOR declined about 8% to 273,000 barrels per day -- this total is on par with the overall decline in U.S. crude oil production in 2020.

Despite a significant decrease in the volumes of CO2 available for injection and storage the CO2-EOR industry was able to maintain production by recycling CO2 rather than having to shut in wells. This strategy shows the resiliency of CO2-EOR during challenging economic conditions, and further supports the viability of this method as a means of storing CO2 and producing lower carbon intensity oil in the U.S.

Thermal maturity, the degree to which the total organic carbon in a formation has been transformed from kerogen to producible hydrocarbons due to heat and pressure, is an important measure for not just the quality of a source rock, but also helps for delineating areas more favorable for unconventional drilling. EORI’s report of thermal maturity of the Mowry Shale in the Powder River Basin provides a detailed map based on a large public T_max data set.

Key observations include:

• Nearly all of the Mowry deeper than 8000’ currently generates hydrocarbons
• The basin axis has shifted slightly westward since the Mowry began generating hydrocarbons
• The Mowry 8000’ line plays an important role in demarcating the over-pressured Mowry and related clay diagenesis.
• The maximum maturity levels in the Mowry are in the “wet gas” stage

Background and objective

How do the high K strikes in core data possibly impact oil production Ash Creek field in Pilot 3?

Outline:

• Introduction & model settings
• Comparison of the simulation results
• Primary analysis of Ash Creek data
• Conclusions

Conclusions

1. The synthetic models of Pilot 3 area are generated and the simulations are completed.
2. The high values of core permeability do impact the production, injection efficiency, and sweep efficiency.
3. In general, an uniform permeability distribution over the entire field is better for high production, high injection and high sweep efficiency over the entire field.
4. However, in a small local area, cells having high permeability seems better for production. seems better for production.
5. High heterogeneity of the field made a high remaining oil in place and a high homogeneity field will produce a high amount of oil.

Is CCUS Feasible in WY? Wyoming’s Unique Position in the World’s CCUS Arena - The Cowboy Unicorn.

The primary objective of the study is to assess the possible implications to GHG emissions associated with this proposed ban and to do so, estimate the drilling and production losses from policies to restrict oil and gas development on federal lands. From that estimate, the emissions impacts are assessed by examining the difference in emissions associated with possible makeup production, compared to the production loss resulting from the ban, or from higher natural gas drilling levels that may be required to make up for lost supplies.
