ABP wells in close

Rig on the move to the well pecuk 01 Lamongan

White Albatros oil wells (ABP) in the village of Jamprong, Sub-District Kenduruan drilled PT Pertamina EP Cepu Field Asset 4 is declared closed. Drilling was discontinued settlement like any other oil wells following the drilling constraints.

"Drilling has reached a depth of peak, but was not pursued at the stage of completion or completion of the said Field Manager of PT Pertamina EP Cepu Field Asset 4 Agus Amperianto yesterday (6/3).

Therefore, rig or drilling tool at the location will be moved. Furthermore, the well is capped and casted. Closure of these wells to safeguard potential underground pressure that may arise. Also, securing the operation and the environment. Therefore, the unpredictable potential emerging from underground. "Completion or completion of the work did not proceed because management wants to evaluate potential problems at a depth of 1,100 meters.

Furthermore, continued the former public relations manager of PT Pertamina, the institute will move to the exploration to other areas, namely in the Well Pecuk-01 in Lamongan. It was to see the potential for oil and gas in the basin East cross beam. One of them in the region in Lamongan.

"Because there is some correlation and estimated surface that should be revisited. several times the problem still occurs dawn hole well bore, ".

Because of its nature or proving exploration drilling and surveys, so could only predicted the problems that occur and how to map the problem. So is the problem underground will appear.

"In the case of wells in this Jamprong, issues that arise at a depth of 1,100 meters that we will have correlated at that depth with drilling plans in the Well Pecuk," he stated.

     Although closed, there is still the possibility of wells ABP reopened. That was done after the known problems that occurred and solutions in accordance with the conditions of the well drilling in Lamongan. "It is possible we will work again on the well ABP by leveraging the data we've gained when driling in ABP01". 

Reported earlier, approaching the peak depth, drilling exploration wells White Albatros 01 obstacles had emerged. From the bursts appear jetted wells or down hole and a spray of water (water kick). So many days officers in the field to focus on completing these constraints. Drilling was conducted from December 20 to a depth of 1,275 meters.

Sumur ABP Di tutup

Sumur minyak Albatros Putih (ABP) di Desa Jamprong, Kecamatan Kenduruan yang dibor PT Pertamina EP Asset 4 Field Cepu dinyatakan ditutup. Pengeboran itu tidak dilanjutkan penyelesaiannya seperti layaknya sumur minyak lain menyusul terjadinya kendala pemboran. 

"Pemboran sudah mencapai kedalaman puncak, namun tidak dilanjutkan pada tahap komplesi atau penyelesaian ujar Field Manajer PT Pertamina EP Asset 4 Field Cepu Agus Amperianto kemarin (6/3).

Karena itu, rig atau alat bor di lokasi akan dipindahkan. Selanjutnya, sumur ditutup dan dicor. Penutupan sumur tersebut untuk mengamankan potensi tekanan bawah tanah yang mungkin timbul. Juga, mengamankan operasi dan lingkungan. Sebab, tidak bisa diprediksi potensi yang muncul dari bawah tanah. "Komplesi atau pekerjaan penyelesaian itu tidak dilanjutkan karena manajemen ingin mengevaluasi potensi permasalahan pada kedalaman 1.100 meter.

Selanjutnya, lanjut mantan manajer humas PT Pertamina itu, pihaknya akan pindah untuk eksplorasi ke daerah lain, yakni di Sumur Pecuk-01 di Lamongan. Hal itu untuk melihat potensi migas di cekungan lawa Timur. Salah satunya di kawasan di Lamongan tersebut.

“Karena ada beberapa korelasi dan perkiraan surface yang harus ditinjau kembali. beberapa kali masih terjadi problem dawn hole well bore,".

Karena sifatnya pengeboran eskplorasi atau pembuktikan serta survei, sehingga hanya bisa memerkirakan masalah yang terjadi dan bagaimana memetakan persoalan. Begitu juga masalah di bawah tanah yang akan muncul.

"Dalam kasus sumur di Jamprong ini, persoalan yang muncul pada kedalaman 1.100 meter itu akan kita korelasikan pada kedalaman tersebut dengan rencana pengeboran di Sumur Pecuk ," tegas dia. 

    Meski ditutup, masih ada kemungkinan sumur ABP dibuka kembali. ltu dilakukan setelah diketahui persoalan yang terjadi dan solusinya sesuai dengan kondisi pengeboran di sumur Lamongan. "Tidak menutup kemungkinan kita akan bekerja lagi di sumur ABP dengan memanfaatkan data-data yang telah kita peroleh saat driling di ABP01,".

Diberitakan sebelumnya, mendekati kedalaman puncak, pengeboran eksplorasi di sumur Albatros Putih 01 sempat muncul kendala. Dari dalam sumur muncul semburan air deras atau down hole serta semburan air (kick water). Sehingga berhari-hari petugas di lapangan fokus untuk menyelesaikan kendala tersebut. Pengeboran dilakukan sejak 20 Desember dengan kedalaman 1.275 meter.
