Gas Field Development Planning Using Reservoir Previous HitModelNext Hit

Abstract

In order to effectively manage the gas reserves in the Badak Field, East Kalimantan, and assure sufficient gas supplies are available to meet the contract commitments, a simulation study of the gas reservoirs is being made. The study enhances Huffco's ability to forecast the availability of gas to meet the future demand.

The modeling program used for this study enables prediction of individual well deliverability performance based on actual reservoir performance. Field prediction performance is then made by combining all reservoirs. The Previous HitmodelNext Hit is capable of incorporating vertical and horizontal flow to simulate gathering system conditions.

The first stage of the study on major reservoirs in the Badak Field has been completed4. The results of the study, which predicts future drilling and compression requirements, will be used to support development planning.

A simplified (TANK) modeling approach was used in this stage of the study and was found to give adequate results. A full scale study of the "A" reservoir with fine gridding of reservoir parameters has been run for comparison.

This paper describes the methodology used in developing the field Previous HitmodelTop and the detail results of modelling "A" and "B" reservoirs of Badak Field. The change of gas deliverability with time of wells in the reservoir is presented. The effects of additional well completions and of installing compressors to reduce abandonment pressures are also described.
