Hi David:
Unfortunately, you did not to mention which species of oak you have on your property, so I can't provide you with a good answer!
Additionally, and for future forestry / horticultural questions you may have in the future, you are blessed to have the largest state forestry agency in the US right in your backyard: the Texas A&M Forest Service.

Please utilize their vast expertise for all your future tree questions in your home state of Texas!
Best, Jay
