Proses pemboran memiliki peran penting dalam industri minyak dan gas bumi karena berfungsi untuk menembus lapisan batuan yang berpotensi mengandung hidrokarbon. Operasi pemboran sering menghadapi permasalahan stuck pipe akibat kondisi lubang bor yang tidak stabil, sehingga diperlukan tindakan fishing job untuk mengambil peralatan atau benda asing yang tertinggal di dalam sumur. Penelitian ini bertujuan untuk menganalisis secara teoretis hubungan antara kondisi lubang bor dan tingkat keberhasilan operasi fishing job. Metode yang digunakan berupa kajian literatur dan analisis konseptual berdasarkan prinsip geomekanika dan mekanika fluida, dengan mempertimbangkan parameter seperti stabilitas lubang bor, geometri sumur, serta karakteristik filter cake. Hasil analisis menunjukkan bahwa ketidakstabilan lubang bor, deformasi geometri, dan pembentukan filter cake yang tebal dapat meningkatkan gaya gesek serta menurunkan efisiensi fishing job. Sebaliknya, pengendalian tekanan lumpur dan optimasi desain fluida pemboran mampu menjaga stabilitas lubang serta meningkatkan peluang keberhasilan operasi. Kajian ini memberikan dasar teoretis bagi pengendalian kondisi lubang bor guna meningkatkan efektivitas dan keselamatan operasi fishing job di lapangan migas.
