DEVELOPMENT OF ULTRASONOGRAPHY FOR DOWNHOLE WELL INSPECTION

Abstract

One technique to increase oil production rate in marginal and suspended wells is solving mechanical
problem. Success parameter to solve the mechanical problem is to identify this problem properly and
accurately. One of the tools to identify the well integrity including mechanical problem in oil and gas
industry is downhole camera used to describe bore hole conditions. Image is very important and is used
as main parameter to determine the production and operation strategy. So, imaging technology transfer is
very important especially on proven technology. Ultrasonography is proven technology in medical discipline
to create image within human body without signifi cant error. This research tries to apply ultrasonography
technology in oil and gas industry. Recently, design and prototype of downhole inspection tools stage III have
been completed. Prototype consists of electronic system, mechanical system and information system included
acquisition system. Laboratory test of these tools has been conducted successfully. Acquisition system uses
memory system within dry battery to avoid operation problem at fi eld test. Several advantages of this tools
are the small number data as per user’s required, user friendly and simple in operation.
