Gentle Ben 2: Black Gold (2003)

With tensions running high between Jack and Fog over plans to drill on his land that abuts the wilderness preserve, Fog announces to the whole town that he isn't drilling for oil, but is opening a natural-spring water business. Jack doesn't believe him, and on the night of the big announcement he is jailed, suspected of sabotaging Fog's well. But Ben and Mark soon uncover a secret that Fog's business partners aren't telling him. In fact, this new venture turns out to be more than Fog expected. It is a race to prove Jack's innocence and uncover the truth before Mark is taken back to the city to live in a foster home.
