Abstract

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

Abstract

Perangkat ultrasonic dipakai untuk investigasi pipa dan lubang-lubang perporasi pada sumurproduksi dan deformasi pada pipa. Sistem instrumen tersebut menggunakan gelombang ultrasonikyang dibangkitkan secara elektronik menggunakan transduser immersion (celup). Pencitraan profifi ldilakukan dengan teknik pantulan dengan menghitung jarak permukaan terhadap senter transduserdan diputar pada sudut 360o . Akusisi data dilakukan mikrokontroler dan komputer yang bekerja secaraotomatis dan real time. Alat inspeksi sumur berbasis teknologi ultrasonografifi diuji coba pada sumurbuatan dimana sumur buatan pada kedalaman tertentu dibuat tidak rata, dan alat tersebut dimasukankedalam sumur pada kedalaman yang telah ditentukan dan bisa mengidentififi kasi dinding sumurdengan permukaan yang tidak rata. Dari hasil pengujian yang dilakukan diketahui sistem mekanikdan elektronik memiliki kestabilan yang baik. Sistem yang dibuat telah mamapu menampilkan profifi lpermukaan dinding sumur simulasi dengan akurasi 1 milimeter.
