Unusual Risks and Uncertainties [Table Text Block]	14. Risks and Uncertainties Concentration of Credit Risk As of March 31, 2024, the Company had combined trade accounts receivable from two customers of $4.0 million and $2.2 million, respectively. During the three months ended March 31, 2024, revenue recognized from these two customers was $2.3 million and $3.2 million, respectively. During the six months ended March 31, 2024 revenue recognized from these two customers was $33.7 million and $6.7 million, respectively. COVID-19 Pandemic The ongoing COVID-19 pandemic has negatively impacted worldwide economic activity and continues to create challenges in the Company’s markets. The COVID-19 pandemic and the related mitigation measures have disrupted the Company’s supply chain, resulting in longer lead times in materials available from suppliers and extended the shipping time for these materials to reach the Company’s facilities. The occurrence or a resurgence of global or regional health events such as the COVID–19 pandemic, and the related government responses, could result in a material adverse effect on the Company's business, financial condition, results of operations and liquidity. As such, we continue to closely monitor COVID-19 and will continue to reassess our strategy and operational structure on a regular, ongoing basis. Oil Commodity Price Levels Demand for many of the Company’s products and the profitability of its operations depend primarily on the level of worldwide oil and gas exploration activity. Prevailing oil and gas prices, with an emphasis on crude oil prices, and market expectations regarding potential changes in such prices significantly affect the level of worldwide oil and gas exploration activity. During periods of improved energy commodity prices, the capital spending budgets of oil and natural gas operators tend to expand, which results in increased demand for our customers services leading to increased demand in the Company’s products. Conversely, in periods when these energy commodity prices deteriorate, capital spending budgets of oil and natural gas operators tend to contract causing demand for the Company’s products to weaken. Historically, the markets for oil and gas have been volatile and are subject to wide fluctuations in response to changes in the supply of and demand for oil and gas, market uncertainty and a variety of additional factors that are beyond its control. These factors include the level of consumer demand, regional and international economic conditions, weather conditions, domestic and foreign governmental regulations (including those related to climate change), price and availability of alternative fuels, political conditions, the war between Russia and Ukraine, instability and hostilities in the Middle East and other significant oil-producing regions, increases and decreases in the supply of oil and gas, the effect of worldwide energy conservation measures and the ability of the Organization of Petroleum Exporting Countries ("OPEC') to set and maintain production levels and prices of foreign imports. Crude oil prices have stabilized over the past 18 months, which may result in higher cash flows for exploration and production companies. Any material changes in oil and gas prices or other market trends, like slowing growth of the global economy, could adversely impact seismic exploration activity and would likely affect the demand for the Company's products and could materially and adversely affect its results of operations and liquidity. Generally, imbalances in the supply and demand for oil and gas will affect oil and gas prices and, in such circumstances, demand for the Company’s oil and gas products may be adversely affected when world supplies exceed demand. Armed Conflict Between Russia and Ukraine A portion of the Company's oil and gas product manufacturing is conducted through its wholly-owned subsidiary Geospace Technologies Eurasia LLC ("GTE"), which is based in the Russian Federation. In February 2022, the Russian Federation launched a full-scale military invasion of Ukraine, and Russia and Ukraine continue to engage in active and armed conflict. Although the length and impact of the ongoing military conflict is highly unpredictable, the conflict in Ukraine could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions in addition to any direct impact on the Company's operations in Russia. As a result of the invasion, the governments of several western nations, including the U.S., Canada, the United Kingdom and the European Union, implemented new and/or expanded economic sanctions and export restrictions against Russia, Russian-backed separatist regions in Ukraine, certain banks, companies, government officials, and other individuals in Russia and Belarus. The implementation of these sanctions and exports restrictions, in combination with the withdrawal of numerous private companies from the Russian market, has had, and is likely to continue to have, a negative impact on the Company's business in the region. During fiscal year 2023 the Company imported $3.8 million of products from GTE for resale elsewhere in the world and since then has imported $1.7 million of products during the first six months of fiscal year 2024. The rapid changes in rules and implementation of new rules on imports and exports of goods involving Russia has also led to material delays in getting goods to or from Russia as port authorities struggle to keep up with the changing environment. If imports of these products from the Russian Federation are restricted by government regulation, the Company may be forced to find other sources for the manufacturing of these products at potentially higher costs. Likewise, restrictions on the Company's ability to send products to GTE, may force our subsidiary to have to find other sources for the manufacturing of these products at potentially higher costs. However, the Company's exports to GTE have historically been limited. Boycotts, protests, unfavorable regulations, additional governmental sanctions and other actions in the region could also adversely affect the Company's ability to operate profitably. Delays in obtaining governmental approvals can affect the Company's ability to timely deliver its products pursuant to contractual obligations, which could result in the Company being liable to its customers for damages. The risk of doing business in the Russian Federation and other economically or politically volatile areas could adversely affect the Company's operations and earnings. It is possible that increasing sanctions, export controls, restrictions on access to financial institutions, supply and transportation challenges, or other circumstances or considerations could necessitate a reduction, or even discontinuation, of operations by GTE or other business in Russia. The Company is actively monitoring the situation in Ukraine and Russia and assessing its impact on its business, including GTE. The net carrying value of GTE on the Company's consolidated balance sheet at March 31, 2024 was $5.5 million, including cash of $2.0 million. In response to sanctions imposed by the U.S. and others on Russia, the Russian government has imposed restrictions on companies' abilities to repatriate or otherwise remit cash from their Russian-based operations to locations outside of Russia. As a result, this cash can be used in our Russian operations, but we may be unable to transfer it out of Russia without incurring substantial costs, if at all. In addition to the products the Company imported from GTE, the subsidiary generated $1.8 million in revenue from domestic sales in fiscal year 2023 and has generated $1.5 million from domestic sales during the first six months of fiscal year 2024. The Company has no way to predict the duration, progress or outcome of the military conflict in Ukraine. The extent and duration of the military action, sanctions, and resulting market disruptions could be significant and could potentially have substantial impact on the global economy and the Company's business for an unknown period of time.
