Hidrat gas merupakan air bebas dan gas alam yang membentuk padatan, yang dapat mengakibatkan saluran gas akan membuntu, terutama di flow line serta akan menimbulkan beberapa permasalahan lainnya. Penelitian ini bertujuan untuk memprediksi pembentukan hidrat gas dengan pengaruh Joule-Thomson Effect yang diakibatkan oleh choke performance.Di gunakan metode Katz untuk memprediksi gas hidrat dengan kisaran tekanan antara 100-1000 Psia.Didapatkan temperatur pembentukan hidrat gas pada tekanan 100 Psia sebesar 0.7005 ˚C,sedangkan pada tekanan 1000 Psia sebesar 17.4766 ˚C. Dari hasil nilai koefisien Joule-Thomson didapatkan 0.003972 K/Kpa. Dari hasil nilai temperatur pada flowline terdapat beberapa temperatur yang berada diatas kurva temperatur pembentuk hidrat gas sehingga berpotensi terjadi hidrat gas pada flowline. Sehingga dapat disimpulkan bahwa beberapa kondisi pada flowline berpotensi terjadinya hidrat gas dan harus dilakukan pencegahan.
Kata Kunci: hidrat gas, efek Joule-Thomson, metode Katz, flow line.
