And here is the Wikipedia entry for the entire state showing the changes in boundaries for the past 30+ years - https://en.wikipedia.org/wiki/Oklahoma%27s_congressional_districts
Oklahoma's 2nd congressional district - Wikipedia
Oklahoma's Second Congressional District is one of five United States Congressional districts in Oklahoma and covers approximately one-fourth of the state in the east. The district borders Arkansas, Kansas, Missouri, and Texas and includes (in whole or in part) a total of 24 counties.[2]
BTW, to me it does look like there may be something going on with the boundaries of those districts. I'm not the only one suspicious of the districts in Oklahoma, mathematical models also point to there not being something right in Dodge.

Oklahoma Watch: Did gerrymandering give Republicans dominance in the Legislature?
A recent federal court ruling could open a new wave of redistricting challenges across the country. And that includes Oklahoma, where Republicans now control 78.5 percent of the statehouse seats — a 10 percentage-point increase since the GOP-controlled Legislature redrew legislative boundaries five years ago.
