Sand Control - SNDC

Petroskills Registerbutton

Sand causes a wide variety of costly problems when oil and gas are produced from unconsolidated reservoirs. The most costly problem is usually the loss of production resulting from formation damage caused by poorly planned and/or executed sand control applications. This course will identify the parameters that must be considered when selecting the sand control technique to be used. Examples, problems and case histories will be examined to illustrate key points. Sand control failures will be used to illustrate the types of problems that can lead to early well failures. The course will also teach how to perform quality control checks during the sand control application to help insure successful wells. Because Sand Control in horizontal wells often proves to be short-lived when incorrectly applied, examples and class problems will focus on correctly choosing successful completion techniques for horizontal wells. Several new promising sand control technologies have been introduced in the last few years such as expandable screens. The proper application of these new technologies will also be thoroughly covered. Attendees will leave this course with a thorough understanding of what is necessary to design and implement cost-effective sand control in producing and injection wells.

Drilling, completion, production and research engineers; field supervisors and production foremen; technical personnel who supply services and equipment.
