Considerable emphasis is being placed upon the use of hydraulic fracturing to stimulate hydrocarbon bearing formations, especially those with low permeability. Unfortunately, the optimization of these fracture stimulations in open and cased holes is impaired due to the lack of information on design parameter values.

This study presents wireline tool usage in providing proper design parameter values for hydraulic fracture treatments and in evaluating the success of such a treatment. Examples of logging suites are provided and methods are presented for converting log measurements into design values. Techniques are discussed and a matrix chart has been developed for relating tool capabilities with design requirements. Recent developments of new logging tools, advances in upgrading existing wireline tool capabilities and digital methods of interpretation have provided industry with a better means of obtaining these design values.

Basic input data required for hydraulic fracture treatment design include information on formation thickness, lithology of the host rocks and candidate treatment zone, permeability, pore volume, temperature, identification of existing fractures, fracture gradients, elastic moduli, perforation verification in cased holes, type and saturation of fluids in the pore space, influx of fluids, cement bonding in cased wells, casing integrity and fracture closure pressure. Assessment of the effectiveness of the fracturing operation can be obtained by determining fluid influx and fracture height,
