Houston American Energy Corp. shares rise 2.20% after-hours as US oil producers face new challenges.

Houston American Energy Corp. rose 2.20% in after-hours trading. The company's stock price increase may be attributed to the news that Bolivia's state-run energy company YPFB expects to receive a total of five diesel and gasoline cargoes through Chile by April 4, including three to be imported from Houston. This news could indicate increased demand for energy products in the region, which could positively impact Houston American Energy Corp.'s business operations and financial performance.
