Recent Developments
Between July 2021 and February 2022, Select completed five acquisitions. Collectively these acquisitions expanded our revenue base and service offerings with many of our key customers and increased our overall service offerings within multiple basins. Effectively integrating the acquired assets and operations is a major focus of ours for the remainder of 2022. Our integration and related efforts include, but are not limited to, increasing revenue through strategic market share gains, regional service line expansion, increased pricing, and achieving operational synergies. These operational synergies are expected to be realized by effectively connecting complementary assets with one another, pairing assets with related services, realizing cost synergies, and selling excess assets.
On February 23, 2022, the Company acquired Nuverra, an energy-focused environmental solutions company, providing environmental solutions, including the removal, treatment, recycling, transportation and disposal of restricted solids, fluids and hydrocarbons for exploration and production companies operating across the U.S., including in the Bakken, Haynesville, Marcellus and Utica Shales. With the Nuverra transaction, we added more than 300,000 barrels per day of permitted daily disposal capacity in Texas, Louisiana, North Dakota, Montana and Ohio. When combined with our existing assets and other recent acquisitions, this brings our company-wide permitted daily disposal capacity to approximately 2.5 million barrels per day.
The Complete Acquisition, Agua Libre and Basic Acquisition and HB Rentals Acquisition improved our financial results in the year ended December 31, 2021, as well as our competitive positioning in the water solutions market. These acquisitions strengthened our geographic footprint and provided access to employee expertise as well as opportunities to expand our growing water recycling business into new areas. The acquisitions also increased our market share and added multiple opportunities for future revenue and cost synergies.
In February 2022, Russia launched a large-scale invasion of Ukraine that has led to significant armed hostilities. As a result, the U.S., the United Kingdom, the member states of the European Union and other public and private actors have levied severe sanctions on Russian financial institutions, businesses and individuals. This conflict, and the resulting sanctions, has contributed to significant increases and volatility in the prices for oil and natural gas, with the posted price for WTI reaching a high of $123.64 per barrel during the Current Period. Such volatility may lead to a more difficult investing and planning environment for us and our customers. While the near-term impact of these events resulted in higher oil and gas prices in the Current Period, the geopolitical and macroeconomic consequences of this invasion and associated sanctions cannot be predicted, and such events, or any further hostilities in Ukraine or elsewhere, could severely impact the world economy and may adversely affect our financial condition.
While the ongoing effects of the COVID-19 pandemic on our operations have decreased in recent quarters, this pandemic has had a material negative impact on our financial results. While we have seen economic recovery and higher oil prices through the Current Quarter and the Current Period, such negative impact may continue well beyond the containment of the pandemic until global GDP levels, associated oil demand and resulting oilfield activity all fully rebound. While we have seen oilfield activity improve considerably and global inventories rapidly normalize with continued demand growth since the low point experienced in 2020, considerable uncertainty still remains. Even with this recent recovery however, we cannot provide assurance that our assumptions used to estimate our future financial results will be correct given the unpredictable nature of the current market environment after the recent elevated volatility in the demand for oil and demand for our services. As a consequence, our ability to accurately forecast our activity and profitability is uncertain.
