Management Gas Rate Production due to Liquid Loading and Erosional Rate Issue, Senoro Field, Sulawesi, Indonesia

Abstract

As we all know that the hydrocarbon consumption is increasing by the day especially gas. Now, in order to meet this ever increasing demand it is essential for us to produce at the required rate over a specified period time. This causes the upstream industry tasked with exploiting natural resources to be forced to produce more than usual, especially gas production. Problems that often occur in gas well are the occurrence of unpredictable liquid loading and mitigation early, and also when the well’s ability is considered capable of flowing a large gas flow rate, an erosive issue will emerge. The erosional aspects are particularly difficult and require special attention in high velocity area if solid particles are present.

In determining the good management gas rate, some correlation that exist for predicting the critical rate required for liquid loading in gas well include Tuner et al (1969), Coleman et al (1991), and erosional rate as the maximum limit of the rate of production using a base design from API RP14E with parameter adjustments (Empirical Coeficient (C) and Pipe Roughness) based on literature studies from several paper publications owned by SPE (Society of Petroleum Engineers). Based on the plotting carried out between the Future Inflow Performance Relationship (IPR), Turner/Coleman Model and also Choke Outflow Performance, using nodal analysis that integrated curves to find out the operating point of the wells.

From the results of the analysis showed that the Senoro field has a safe limit on gas production which becomes a reference later, so that the problems of liquid loading and erosive issue do not occur or can be mitigated early because we could predicted the pressure in which the problem of liquid loading may occur.
