Abstract

In early 2014, PT Pertamina EP Asset 1 Jambi Field was re-opening X-02 Well to opened gas layer that will be produced to realize gas purchase agreement. For knowing production capability at X-02 Well, the final assignment about analysis of gas well deliverability and reservoir characteristics at its well has done by using modified isochronal test. In the final assignment implementation in PT Pertamina EP Asset 1 Jambi Field from March 31th 2014 to June 13th 2014, the author was doing literature study and then observation directly to the field, modified isochronal test with field operator, collected primary data from the result modified isochronal test and the result bottom hole pressure from electric memory recorder, collected secondary data from reservoir data and PVT data, and then all of data was calculated and analyzed about gas well deliverability and reservoir characteristics at X-02 Well. From the result of analysis was knowed that absolute open flow potential at X-02 Well has value 6.7114 MMSCFD and to realize production target 2.5 MMSCFD used bean size 13 mm with 2.8389 MMSCFD production. Productivity of X-02 Well knowed from index productivity on actual condition 11.28 MSCFD/Psi and index productivity on ideal condition 18.59 MSCFD/Psi. Based on pressure build up test analysis with Horner Plot method, knowed that reservoir pressure have value of 2106 Psi, capability to flow reservoir fluid classified on good level with effective permeability 50.53 mD, and indicated there has been a formation damage around the wellbore based on skin factor value +3.77 and flow efficiency 0.61.
