Di bawah ini beberapa contoh alasan dilakukannya pengeboran berarah atau horizontal (Directional and Horizontal Drilling).
\na. Inaccesible Location Drilling<\/strong>
\nBeberapa reservoir dengan kondisi di permukaan yang tidak memungkinkan untuk dilakukan pengeboran lurus\/vertical akan sangat cocok untuk dilakukan pengeboran berarah atau horizontal (Directional and Horizontal Drilling). Teknik ini adalah salah satu dari teknik pengeboran berarah yang paling umum dilakukan untuk mencapai lapisan yang tidak dapat dicapai dengan cara yang biasa, sebagai contoh reservoir yang terletak di bawah kota, di bawah lahan pertanian\/perkebunan, dll. Gambar 3.7. memperlihatkan formasi yang berada di bawah perkotaan sehingga dilakukan pengeboran berarah atau horizontal (Directional and Horizontal Drilling).

b. Multiple Well Drilling<\/strong>
\nBila suatu lokasi pengeboran memiliki keterbatasan area pada permukaan sehingga tidak mungkin dilakukan pengeboran banyak sumur dengan letak yang berbeda. Hal ini bisa diatasi dengan melakukan pengeboran multiple well. Yakni mengebor pada satu lokasi dengan banyak sumur yang dibuat, untuk itu dilakukanlah pengeboran berarah atau horizontal (Directional and Horizontal Drilling).Multiple well drilling ini sering dilakukan pada pengeboran lepas pantai dari suatu platform tunggal atau dari suatu tempat yang terpencil. Gambar 3.8. memperlihatkan suatu platform yang melakukan Multiple well drilling.

c. Salt Dome Drilling<\/strong>
\nPada daerah yang didapati kubah garam (salt dome) yang letaknya berada di atas reservoir minyak, pengeboran lurus\/vertical tidak mungkin dilakukan. Karena bila pengeboran menembus kubah garam (salt dome) akan mengakibatkan masalah yang serius terutama akan terjadinya blow out sehingga perlu dilakukan pengeboran berarah atau horizontal (Directional and Horizontal Drilling) yangakan mengarah langsung ke reservoir minyak.

d. Side Tracking atau Straightening<\/strong>
\nKadangkala dalam melakukan operasi pengeboran lurus\/vertika terjadi pembelokan yang sangat parah sehingga menjauh dari target, sehingga perlu untuk meluruskan kembali lubang sumur tersebut. Untuk itu dilakukan side tracking dengan melakukan pengeburan berarah. Atau pada kejadian dimana fish yang tidak dapat diangkat dan terkubur dilubang bor, pengeboran harus menghindari fish tersebut agar peralatan pengeboran tidak rusak maka dilakukan side tracking.<\/p>\n

e. Relief Well Drilling<\/strong>
\nPada kejadian sumur yang blow out, salah satu cara untuk menanggulanginya adalah dengan mengebor atau membuat relief well. Relief well merupakan sumur yang dibuat di dekat sumur yang blow out dengan tujuan untuk mengalirkan fluida yang mengakibatkan blow out sehingga dapat dikendalikan. Biasanya relief well dilakukan dengan pengeboran berarah atau horizontal (Directional and Horizontal Drilling).
