    • obtained a voluntary dismissal of a lawsuit challenging post-production expenses;
    • prosecuted and defended quiet title actions; and
    • obtained a voluntary dismissal with prejudice of a lawsuit challenging the validity of an oil and gas lease (dismissal before the decision on a pending motion to dismiss).
