UTWID 5.0 is a PC-based simulator to predict injectivity decline and fracture growth in water injection wells. UTWID assists the operator in designing water injection facilities for waterflooding applications, pressure maintenance, and produced-water disposal. For more information, see the enclosed brochure and visit www.utwid.com. The workshop will provide a demonstration of the capabilities of UTWID 5.0. § Learn how UTWID 5.0 can aid in designing injection facilities. § Learn the physics behind the simulator. § Listen to case studies that demonstrate the economic advantages achieved by operators using UTWID 5.0.
