The purpose of this bill is to update and modernize the minimum spacing requirements for the drilling of horizontal deep wells to recognize changing drilling practices and techniques developed in recent years, which will allow exploration and production companies to implement evidence based best practices. The bill would establish no spacing limitations on wells that are operated by the same operator or operators that agree in writing to specific spacing limitations. It limits setbacks from unit and lease boundaries between different operators and limits the spacing between the wells of different operators. It also limits the distances that may be established to only those between the estimated productive intervals of horizontal deep wells and not the entire well bore.
