Title: 2012 Surprise 3D Seismic Survey Interpretation Report

Abstract: The Surprise 3D Seismic Survey was conducted in an area located in the western half of EP-115, the latter being located four hours' drive west of Alice Springs. The seismic coverage in the Surprise area is approximately 1 line per 4 km2. A seismic 3D was acquired as a result of the oil discovery by Central Petroleum Ltd - Surprise-1 was re-entered (Surprise-1R) and side-tracked (Surprise-1R HST1, re-entry horizontal sidetrack-1). The 3D grid straddles the subsurface oil pool. Terrex Seismic acquired the seismic data, Terrex Spatial carried out the surveying, contractors pre processed the field data and DownUnder GeoSolutions processed the data.
This report has found that The oil accumulation at Surprise-1R is pooled in a three-way dip fault-bound closure; thereby, indicating that across-fault seals are capable of holding back hydrocarbons. Thus, other accumulations could be present in fault bound traps even though the basin has been severely shortened and thrust faults abound. A deeper play directly below the Base Giles Creek Dolostone unconformity may exist but the interpretation of any potential trap is not forth-coming within the 3D area.
NOTESurvey was completed under EP115 before L6 was granted.
