In addition to the Boost.Spirit component that Joakim mentions there's also the practical issue that almost all of our unit tests target Boost.Test as a framework. For instance, the header <boost/test/unit_test.hpp> is included 193 times across the OPM code base. If we're going to replace that with another framework--Google Test might be an alternative--it is going to require some work to rewrite the tests.
That said, raising the minimum C++ language version to C++17 will allow us to replace most of our other usage of Boost; notably regular expressions and Boost.Filesystem.

It is simple to replace with std varieties, but there might be a performance hit.
