Design and Performance Evaluation of Accelerated Weight Drop (AWD250 v1.0) as a Seismic Source for Shallow Seismic Surveys

HEAD OF TEAM : Dr. Alfian Bahar TEAM MEMBERS : Dr. rer. nat Moch. Rachmat Sule; Fernando Lawrens, ST., MT.   The acquisition of seismic reflection data involves the process of generating and recording the seismic wave field on the surface of the earth. The success of the acquisition process in producing a high quality […]

CO2 Gas Liquification Technique Through Subsea Pipe Flow To Increase National Gas Production

CO2 Gas Liquification Technique Through Subsea Pipe Flow To Increase National Gas Production

Gas production with a very high CO2 content requires special treatment to separate the methane from CO2. The separation also requires high capital expenditure (CAPEX) and operational expenditure (OPEX). The challenge is higher, when the gas is being produced on offshore, and only narrow space that available on the platform for separation process. One proposed […]

The Hydrogeology Model of Cisarua Sub-District is Based on Rainfall, Geoelectric and Gravity Data

Dr. Darharta Dahrin, Dadi Abdurrahman ST., Mt. Geophysical Engineering Program, Bandung Institute of Technology *Correspondence: darharta@gmail.com or dahrin@gf.itb.ac.id   Abstract Cisarua has a morphology of hills with the area of ridges and valleys. Generally, in this area, the groundwater flow is quite large and the variation of the groundwater mass is highly dynamic which is […]

Cyclic Injection of CO2 – N2 as a New Method of Enhanced Coal Bed Methane Gas Recovery

Cyclic Injection of CO2 – N2 as a New Method of Enhanced Coal Bed Methane Gas Recovery

Doddy Abdassah, I Wayan Rakananda S., Dedy Irawan, Irianto P. Binsardo Petroleum Engineering Department, Institut Teknologi Bandung, Bandung, Indonesia.   As one example of unconventional source of hydrocarbon, coalbed methane is the one of the most developed compared to the other unconventional sources. Started on 1980s, the early coalbed development of coalbed methane production faced […]

Seismic Stratigraphy Model Identification on Towuti lake, South Sulawesi

Head of Team : Dr. Wahyu Triyoso Team Members : Prof. Satria Bijaksana and Silvia Jannatul Fajar, MT.   Lake Towuti sediment deposits have special feature in reconstruct the basin formations. It lies on ophiolitic rock of East Sulawesi Opihiolites. Seismic reflection survey was used to reveal the subsurface sedimentary of the lake. Surface related […]

Integration of 3D Seismic Attributes for Preliminary Shallow Geohazard Identification in Deep Water Exploration Area with No Well Data

Integration of 3D Seismic Attributes for Preliminary Shallow Geohazard Identification in Deep Water Exploration Area with No Well Data

HEAD OF TEAM : Prof. Sigit Sukmono TEAM MEMBERS : Dona Sita Ambarsari, ST., MT.   Introduction Drilling in the deep water is very challenging as the safety of drilling rigs and other installations could be threatened by the presence of shallow geohazards. These hazards are a global problem, and while the industry has matured […]

Gas Production Strategy of CBM Formation using Sacrifice Well

Gas Production Strategy of CBM Formation using Sacrifice Well

Coal Bed Methane (CBM) is an unconventional resource that shows great promise, particularly in Indonesia, whose CBM reservoir is relatively thick. Gas reserves of CBM are estimated at 450 TSCF in Indonesia, which makes it, the 6th largest CBM-containing country in the world. However, regulatory and technical limitations slow the progression of the exploitation of […]
