Understanding on the depositional model becomes important to enhance the interpretation. That knowledge can be achieved by observing the on-going sedimentation system or examining the outcrops of ancient depositional system. Hydrocarbon discoveries in the deformed turbidite sequences within the Kalimantan Deep Water Block have commenced further exploration on the similar deposits elsewhere. Turbidite deposits are a thick series of fine to coarse grained sediments deposited by density currents on an unstable basinal slope. It has long been assumed that turbidite contains abundant fine grained particles that act as pore plug and thus decreasing the porosity, where in turn made the turbidite sequences unlikely to be a hydrocarbon reservoir. However, turbidite depositional processes are polygenetics, where different depositional processes were working together in different part at the same time. It often produces distinctive characteristics in sandstone and makes their reservoir quality varied, including some clean sand. The Pre-convention IAGI 2007 Field Trip will visit two physiographic zones in Central Java which have extensive turbidite deposits, the Southern Mountains and the Kendeng Zone, respectively. Participants are invited to examine various turbidite sequences as well as their characteristics and discuss their possibility in a petroleum system. In the Kendeng Zone, participants have opportunities to observe strong deformational processes had produced various structural traps. Department of Geological Engineering UGM has conducted numerous geological field studies on both zones, particularly on their tectonostratigraphy. This field trip is considered important as a means of knowledge and experiences exchanges with industrial colleagues is needed to enhance the researches and their application to academic purposes. *Field Trip Itinerary * ** ** *Day 1 : Yogyakarta * *Participants stay over night at hotel, class room night * ** *Day 2: Yogyakarta – Southern Mountains – Western Kendeng – Surakarta * *Stopsite 1: **Widoro River (clean sandstone in turbidite sequences of the Sambipitu Formation) * *Stopsite 2: **Kedungombo Lake (clean sandstone in a fan lobe of the Kerek Formation) * *Stopsite 3:** **Alaskobong (folded fine-grained sandstone series of fan lobe reservoir of the Kerek Formation) * *Overstay will be at the Lorin Hotel, Surakarta. * ** ** *Day 3: Surakarta – Central Kendeng – Ngawi – Surakarta * *Stopsite 4: Jengkawal (overturned sandstone of fan lobe reservoir of the Kerek Formation) * *Stopsite 5: Ngrancak (possible long distance hydrocarbon migration to fluviatile sandstone of the Kabuh Formation) * *Stopsite 6: Ancient Ngawi (stratigraphic problems with Pucangan and Kabuh formations). * *Drive back to Surakarta to catch the late afternoon flight to Jakarta. * ** *Facilities * *1.**Safety and air conditioning tourist bus * *2.**Overstay at five stars hotel (the Lorin Hotel, Solo) and laundry service for 1 set of clothes. * *3.**Food and drink during field-trip (lunch and snack) * *4.**Certificate * *5.**Field-trip kit (guide book, field ransel, stationery, umbrella, t-shirt, hat and boot). * ** *Note * *The registrants will get 5% discount if registered and due date of payment before 8th October 2007 * *Cancellation before 20th day of "D" day will be charge 25 % of cost. * *No cancellation before 10th day of "D" day * ** *Registration and Payment * *Please return this filled form to * *JCB 2007 Secretariat Office * *ETTI (Exploration Think Tank Indonesia) * *Jl.
