Summary of Executive Orders Actions taken by the Biden administration in January 2021 which will have a direct impact on Wyoming’s economy. 

This study estimates the investment and production losses from policies to restrict oil and gas development on federal lands. The first policy is a moratorium on all new federal leases. The second involves an outright drilling ban on all onshore federal lands. The scope of this inquiry includes a study region that includes eight states: Wyoming, New Mexico, Colorado, Utah, Montana, North Dakota, California, and Alaska. These lost opportunities are estimated by first projecting how drilling and production activity is likely to evolve from 2021 through 2040 and then identifying what portion would be affected by the two policies.

The Institute predicts unconventional drilling will become less important while improved and enhanced recovery methods in conventional reservoirs will be of critical importance to Wyoming’s oil and gas sector due to expected oil prices. The Institute offers immediate changes be considered to the Wyoming Oil and Gas Conservation Commission (WOGCC) policies regarding the approval of idle well bonds to initiate construction.

In their study, Open Water Capital Partners highlights solutions to mitigate the long-term effects of a sustained downturn in coal, oil and natural gas and introduces strategies to limit the downturn’s impact while supporting Wyoming’s energy industry.

Open Water Capital Partners introduce strategies to curtail this impact to Wyoming’s economy with a three-pronged approach providing “immediate financial relief to operators, access to longer term liquidity amidst the volatility, and establishes a platform to more broadly diversify state revenue streams. 

Wyoming, perhaps more than any other state, is dependent on revenues generated from the development and sales of minerals within its borders and has a vested interest in ensuring that its resources are properly and efficiently exploited. Maximizing the efficiency of oil and gas production in Wyoming is one of the primary goals of the Enhanced Oil Recovery Institute (EORI). Potential methods or practices that can improve or enhance the recovery efficiency of oil and gas production in the state are of paramount interest. Likewise, those policies or practices that hinder such efforts are also important to discuss.

Wyoming has nearly one billion barrels of proved oil reserves, a significant portion of which is still on primary production. Assessing the potential for secondary recovery from current oil fields is always a daunting task and requires evaluations regarding whether any given field will respond favorably to secondary recovery efforts.

This paper makes general assumptions regarding the feasibility of using a water flood to enhance oil recovery in a field based on publicly available data. The conclusions resulting from these assumptions are meant to be a guideline for the potential of future water flooding and are not meant to provide detailed evaluations of any given field’s ultimate recovery.

The purpose of this study was to report on the effectiveness of the Hyperscratcher tool in improving production or injection by cleaning out boreholes that have reported problems with scale, paraffin, or asphaltene build-up.

The Hyperscratcher tool was initially designed and used in California in the 1980s for workovers; as yet it has not been widely used in Wyoming.

Test results show use of the Hyperscratcher Tool significantly improved production in 7 of the 8 wells tested with production improvement varying from 20% to 120%.

Polymer-augmented waterflooding of the Minnelusa in Wyoming has proven to be a successful method for improving production in most cases compared to normal waterfloods. Polymer is a lowcost, low-risk option when considering a method for enhancing production of a particular field. Its primary function is to improve the mobility ratio of the injected water by increasing its viscosity, thereby improving the volumetric sweep and conformance within the reservoir.

Advantages of using polymer include: (1) low cost, (2) preventing early water breakthrough, (3) improving volumetric sweep and conformance, (4) increasing oilwater ratios, (5) mobilizing oil that would likely have been bypassed under normal waterflood conditions, (6) mitigating heterogeneous permeabilities within the reservoir, and (7) other enhanced oil recovery injection technologies can still be applied after the polymer flood. Most, but not all, Minnelusa fields examined exhibited improved recoveries using polymer compared to fields under conventional waterfloods. Uneconomical polymer floods can be caused by a variety of factors, chief of which is the failure to properly understand the internal architecture of the reservoir prior to initiating the flood.

The purpose of this survey is to provide a comprehensive status report of active CO2 EOR projects in the U.S., as of end-of-year 2019. This survey provides the first update of CO2 EOR project data since the final publication of the Oil & Gas Journal (OGJ) EOR Survey in 2014.

The 2019 U.S CO2 EOR survey shows that incremental oil recovery from CO2 EOR in the U.S. has held steady at approximately 300,000 barrels of oil per day. A total of 3.0 Bcf per day of CO2 is purchased for CO2 EOR, including 1.0 Bcf per day from “industrial” sources, which represents an increase of 30% over the last seven years.

Carbon management, in the form of CO2 capture and storage, is the most viable pathway to meeting significant carbon emission reduction targets over the next several decades. This survey demonstrates the value and potential of CO2 EOR to the overall carbon management strategy in the U.S.

Periodic updates will be made to this survey to include the latest CO2 EOR project data available. This publication is intended as a public resource for petroleum and energy industry stakeholders, and is offered free of charge by ARI. The next survey update is anticipated for Fall 2021.
