Sean Spicer holds the daily press briefing at the White House on May 15, 2017 in Washington, DC.
The conference announced Spicer's September 28 keynote on Wednesday morning, noting that it will be among his first major public appearances since stepping down from his position as the White House's chief spokesman.
Politico reported that Spicer will make another speech on September 11 in New York City at investment bank Rodman & Renshaw's annual conference.
Shale Insight's conference program notes that Spicer's address "will provide an inside perspective of now-U.S. President Donald Trump's administration and policy plans regarding the U.S. energy revolution and our new-found wealth of natural gas, particularly in the states of Pennsylvania, Ohio and West Virginia."
Spicer will also discuss his experience in the White House to showcase "approaches to minimizing sensationalized public protests reported by the media" and "preventing foreign oil producing countries and cartels form holding America hostage."
Spicer's prepared speech at the end of the month comes after news that he had signed with Worldwide Speakers Group, which represents other prominent Republicans such as Fox News personality Tomi Lahren and former House Speaker Newt Gingrich.
However, Spicer's post-White House career will not be limited to lucrative speaking engagements. In an interview with Axios, Spicer said he is considering many options, including consulting, paid television appearances in Ireland and the United Kingdom, as well as a potential book deal.
Last year, then-candidate Donald Trump delivered the Shale Insight keynote address.
