Bengkulu earthquake was happened on Wednesday, May 5th 2010 at 23:29:03 WIB (UTC-7) with magnitude 6.5 Richter scale. The Epicentrum was very close to Mentawai Fault System located on latitude 4.063◦S and longitude 101.085◦E with depth subsurface 27 kms. It was occurred the result of the Indian Ocean Plate-Australia’s activity with low angled-subducted beneath the island of Sumatra. Shaking Bengkulus seismicity impacted subsurface in the XX Area which situated on South Palembang Sub-Basin part of South Sumatra Basin (SSB) about 200 kms far away from the epicentrum. Due to XX Area has some producing wells so that the seismicity activities as hypothetically impacts to Subsurface Wellbore which has caused some wells casing problems in the same depth. The wells casing problem shown after conducted routine sand bailer by Sand Line Unit, it was a downhole device used to remove debris sands or similar small particles around the fishingnecks of downhole tools or equipment in the wellbore, and then Sand Bailer tools got scratch at one side body. Similarly, Sand Bailer tools couldnt lowered until Total Depth and got samples sands slightly. At the end, it has impacted to well performance to produce oil in the XX Area.
