Abstract

After completing a waterflood activity, the need of enhancing oil recovery (EOR) is essential. The selection of appropriate EOR methods that will be applied to particular field, as an effort to increase oil recovery, mainly depens on the reservoir characteristics and fluid behaviors.

Abstract

The fundamental control in petrophysical properties of carbonate rock can be quite different from sandstone, there-fore it needs different technique in permeability assessment. In this study we proposed a technique to assess permeability using probe permeameter for carbonate rock.The technique applied Multiple Tip Size (MTS) Probe permeameter which provides speedy, non destructively sampling at a significantly increased density. The key feature of the MTS is the use of different tip size. By using the MTS probe permeameter, the data can be screened to assess the appropriate data
CURRENT USES AND FUTURE CHALLENGES FOR ZEOLITE IN THE INDONESIAN OIL AND GAS PROCESSING INDUSTRY A.S. Nasution; Chairil Anwar; E. Jasjfi

Abstract

Oil and gas industry uses zeolite as an adsorbent to reduce moisture content of natural gas in LNG Plant, and as catalyst to convert the heavy petroleum fractions feeds into light clean fuels in refinery.Low quality crude oil, low residual fuel demand, and an increased demands and spesifications for light products (gasoline, kerosene, and diesel oil) and petrochemical products, future challenges for utilization zeolite as cracking catalyst in refinery are encouraging.
CHROMATOGRAPHIC CHARACTERISATION OF POLYPYRROLE-BASED CONDUCTIVE POLYMER Hawick Chriswanto

Abstract

A chromatographic study on the properties of polypyrrole-based conductive polymers has been carried out. The polymers were chemically axidantively prepared and coated directly onto silica particles and packed under high pressure into stainless steel chromatography columns. A series of small molecules were used as test compounds and chromatographic measurements were performed under reserved phase condition. The study revealed the properties of the polymers, such as their hydrophobicity, which were deduced from their behaviour in the interactions with the test compounds.
A COMPUTER PROGRAM TO PREDICT SCALING TENDENCY OF OIL-FIELD WELL WATER COMPOSITE S. Mulyono

Abstract

A simple computer program based on LOTUS 1-2-3 Release 2.3 or 2.4 has been prepared for scaling tendency prediction of oilfield well water composite. Up to four individual well waters can compose the composite. Scaling material considered are calcium carbonate, calcium sulphate, and barium sulfate.

Abstract

The utilization of natural gas as vehicles’ fuel (BBG) is now being developed in Indonesia for either private cars or public cars. The reasons of using BBG are (1) the price of BBG is lower than fuel oil (BBM), (2) the cost of BBG’s cars maintenance is lower than BBM’s cars maintenance, (3) BBG is an environmentally friendly fuel. Moreover, BBG’s infrastructure has been built in some big cities.
A HYPOTHETICAL COMBINATION METHOD TO PROVIDE DATA FOR FORMATION WATER COMPATIBILITY Herlan Adim

Abstract

Industrial Water Technology, information concerning formation water, is required primarily in water injection projects to define the possibility of injection well plugging.
POTENTIALS OF BACILLUS STEAROTHERMOPHILLUS FOR ENHANCED OIL RECOVERY A LABORATORY EXPERIMENT M. Udiharto; S. Kadarwati; E. H. Legowo; M. Rahman; E. Jasjfi

Abstract

B. stearothermophillus was isolated from among microbes recovered from a formation water from an oil field in Indonesia, where the temperature was 55°CLaboratory experiment was conducted to measure the growth, and to study the effects of its activity on the physical characteristics of reservoir rock and crude oil in an oil well.
SYNTHETIC SEISMIC RECORDS FROM HETEROGENEOUS MEDIA USING THE RAY TRACING METHOD Ahmad Yusuf; Djoko Rubyanto; Suprajitno Munadi

Show Abstract | Download Original | Original Source | Check in Google Scholar | DOI: 10.29017/SCOG.18.1.1102

Abstract

Ray tracing method can be used to generate artificial seismic records from a heterogeneous medium which depend on the structure and stratification of the geologic model. The ray tracing method is a forward modelling process which is able to visualize the seismic wave propagation and its corresponding seismic record from different geologic models, so that the dominant parameters which control the model can be understood.
UTILIZATION OF REMOTELY SENSED DATA TO GEOTHERMAL, OIL AND GAS DEVELOPMENT M. Husen

Show Abstract | Download Original | Original Source | Check in Google Scholar | DOI: 10.29017/SCOG.18.1.1103

Abstract

Some of LEMIGAS experiences in the utilization of remotely sensed data will be briefly discussed, these are : Jambi Sub Basin and North East Java Basin for Preliminary and advanced oil and gas exploration respectively. Dieng field for geothermal exploration, and Balikpapan offshore for sea water quality assessment. It is hoped, through this information, better understanding of the operational aspects and appreciation of the subject can be achieved.
