Abstract
A method and apparatus for laboratory simulation of the dynamic formation of sand arches in production of oil and/or gas from unconsolidated or poorly consolidated wells is disclosed. An ultrasonic transducer is disposed opposite a perforation in a member simulating the casing of a well and the simulated well is operated at conditions approximating those of interest in the field. The acoustic transducer is moved incrementally across the perforation and measurements of the distance between the transducer and the formation are measured. These can then be used to generate a profile of the surface of the formation behind the perforation. Preferably, an ultrasonic transducer which emits a focussed beam of acoustic energy is employed.
