USE OF 3D SEISMIC DATA TO OPTIMIZE SITING AND COMPLETION OF MULTIPLE HIGH VOLUME BRINE DISPOSAL WELLS
Increasing importation of LNG and LPG into the Gulf Coast and increased production of domestic natural gas resources has resulted in the development of additional salt cavern storage capacity on the Spindletop Salt Dome located near Beaumont, Texas. A total of five storage caverns for natural gas and one brine production cavern currently are operated on the dome. Ownership or lease rights have been acquired over a majority of the remaining useable salt of this domal structure. Cavern development schedules and operational considerations has led to a co-use approach to the siting of the storage caverns but more particularly to the siting of a nine well grouping of high volume brine disposal wells located off the dome. Domal structures are intrusive bodies resulting in radial faulting around the salt stock and often associated with other regional fault trends. An extensive 3-D data suite that encompassed both the domal structure and the area of the proposed brine disposal wells was obtained and evaluated to optimize the location of the brine disposal wells with respect to potential faults which resulted in a more suitable arrangement of wells. The same data suite was also evaluated with respect to selected cavern locations on the dome. The evaluation was reviewed by the Texas permitting authorities and permits have been issued for all of the proposed disposal wells and storage caverns. A description of the wells and the geologic profile is presented along with description of the related surface facilities. Additionally, well logs of the brine wells were also correlated with the 3-D seismic data for high permeability and porosity zones. Various horizons were identified and horizontal slices through the entire disposal area were made and continuity was evaluated. Examples of the horizontal slices are included herein.
