Salah satu tantangan dalam pemboran deepwater biaya sewa rig yang sangat tinggi,sehingga kegiatan pemboran diperlukan secepat mungkin untuk menghemat biaya. Sumureksplorasi F merupakan sumur yang terletak di Lapangan M dengan target kedalaman 14,030 ftpada struktur Ngimbang Karbonat. Dari studi G&G dan berdasarkan sumur offset dapat diketahuibahwa lapisan yang akan ditembus adalah Lidah Shale hingga kedalaman 4,650 ft, kemudianPaciran hingga kedalaman 5,660 ft, lalu Cepu Shale hingga kedalaman 10,030 ft, dan yangterakhir adalah Ngimbang Karbonat hingga kedalaman 14,030 ft. Terlihat bahwa ada banyakkemungkinan masalah terkait hole cleaning dikarenakan lapisan shale yang panjang danditambah dengan masalah mud window yang tipis. Untuk mengatasi masalah hole cleaning danmud window yang tipis, pada trayek 26” dilakukan pemompaan 2200 GPM dengan konsentrasicutting yang dijaga sebesar 10% dan ROP yang mampu dicapai adalah 291 fph. Kemudian padatrayek 17-½” dilakukan pemompaan 1600 GPM dengan konsentrasi cutting yang dijaga sebesar3% dan ROP yang mampu dicapai adalah 170 fph. Lalu pada trayek 14-¾” dilakukan pemompaan1300 GPM dengan konsentrasi cutting yang dijaga sebesar 3% dan ROP yang dapat dicapaisebesar 208 fph. Selanjutnya adalah pada trayek 12-¼” dilakukan pemompaan 1200 GPM dengankonsentrasi cutting yang dijaga sebesar 3% dan ROP yang mampu dicapai sebesar 306 fph. Lalupada trayek 10-7/8” dilakukan pemompaan sebesar 832 GPM dengan konsentrasi cutting yangdijaga sebesar 3% dan ROP yang dapat dicapai sebesar 285 fph. Dan trayek yang tera khiradalah 8-½” dimana dilakukan pemompaan sebesar 768GPM dimana dijaga agar konsentrasicutting sebesar 3% dengan ROP yang mampu dicapai adalah 433 fph.

Sumur X ini merupakan sumur penghasil minyak yang sudah diproduksi sejak tahun 2005. Pada sumur ini terjadi kerusakan pada ESP (Electric Submersible Pump) sehingga perlu dilakukan penggantian ESP. Kesulitan yang ditemui pada saat ESP akan diganti adalah terjadinya lost circulation pada saat sumur akan dimatikan. Penyebab hilangnya fluida ke dalam formasi dianalisa berdasarkan data yang ada, diantarnya tekanan hidrostatis yang dihasilkan fluida untuk mematikan sumur, tekanan reservoir, dan tekanan rekah batuan.Kemungkinan penyebab lost berdasarkan analisa yang dilakukan adalah fluida hilang ke dalam formasi B200 melalui lubang perforasi dengan interval 7 ft pada kedalaman ±1070 ft. Kemungkinan ini didukung dengan data lapangan diantaranya adalah tekanan casing dan tubing saat sumur di shut-in dan berdasarkan sejarah formasi B200.Untuk mengatasi permasalahan yang diakibatkan oleh lost circulation ini agar pekerjaan workover bisa dilanjutkan adalah pemilihan XCD Polymer sebagai pengental kill fluid dimana kill fluid yang digunakan untuk mematikan sumur adalah KCl, dimana fluida ini solid free dan tidak merusak lingkungan serta ramah lingkungan dan tidak melebihi tekanan hidrostatik yang diperlukan untuk mengimbangi tekanan reservoir, dimana tekanan overbalance sebesar 200 – 300 psi. Pemilihan konsentrasi polimer harus dilakukan agar memenuhi kriteria dimana fluida harus bias mempertahankan viskositasnya pada temperatur reservoir dan crosslinker ditambahkan untuk mencegah lost kembali terjadi saat keadaan static. Penambahan crosslinker disebut sebagai crosslinked gel system, dimana penambahan crosslinker ini ditujukan untuk mempercepat gelling time dari fluida tersebut, sehingga mencegah dan meminimalisir terjadinya lost pada saat sirkulasi dihentikan atau saat keadaan statis karena gelling time dari fluida ini tercapai dengan waktu yang relatif cepat dengan penambahan crosslinker.

When members of the Indonesian Armed Forces (TNI) commit a crime or have allegedly committed acrime, whether that is a criminal act regulated in the Criminal Code or outside the Criminal Code and acriminal act enshrined in the Criminal Code. The TNI member was based on the provisions of Law Number 39of 1997 concerning Military Courts and could not freely and independently elect his legal counsel who wasbelieved to be able to assist his legal process. The authority to determine legal counsel is determined by thePerkatra Submission Officer (PAPERA). This is very different from non-military citizens when committing acrime, he is free to appoint and determine their own legal counsel. The purpose of writing this thesis, namely;First, to find out the freedom to choose legal counsel for military members involved in criminal cases inmilitary criminal justice is associated with the principle of equality before the law, Second, to find out the legalconsequences for legal counsel who do not get permission from the Conquering Officer (PAPERA).This type of research can be classified as normative legal research. Because this research is morespecific to the principle of equality before the law or equality of citizens before the law. Sources of data usedare primary data legal materials, secondary data and tertiary data. For the technique of collecting researchdata, the authors conducted a literature study.From the results of the research based on the formulation of the problem, it is known that the applicationof the principle of equality before the law in selecting legal advisors for military members committing a crimeor to be suspected of having committed a crime is not appropriate as the principle should be. The TNI's internalunit has indeed provided legal aid services based on the determination from PAPERA. But for military memberswho want to use legal aid services from outside the TNI must be based on permission from PAPERA. If they donot get permission from PAPERA, the legal advisor / advocate cannot go to court to help the legal process ofhis client. Meanwhile, there is no legal provision for PAPERA to determine whether or not the advocate iseligible for permission. Even if a TNI member commits a criminal offense, based on the constitution of a TNImember it is still a citizen who must get the same treatment before the law. So it is necessary to do a legalrenewal of Law Number 39 of 1997 concerning Military Justice. Especially related to the freedom of a militarymember to determine his legal counsel.Keywords: Equality before the law, Legal advisor, Papera
