Abstract

At northern part of Sumatera Indonesian onshore many drilling issues were encounteredin the area, in particular the overlying shales above the pay zones in the high deviatedtrajectory wells. Since the last well drilling in this area was 70’ era, so that limited data isanother drilling engineering challenge, especially to provide an accurate drilling fluid. Tocombat the drilling issues, utilization of pre-treated wellbore strengthening agent wasapplied to reduce well bore issues and strengthen the well with an effective filter cake. In Northern Sumatera Indonesian onshore well in Indonesia was used as a case study. First a brief understanding and fundamentals of geo-mechanics is described in reference to wellconstruction as well as filter cake fundamental to protect the hole stability. Results,observations and conclusions were drawn upon using a case study comparing a well ononshore in Indonesia which had many drilling problems such as stuck pipe/differentialsticking and washouts/hole enlargement issues related to well bore stability, after using thewellbore stability agent, the problems that encountered significantly decrease.

Abstract

Tujuan pengoptimalan pengeboran adalah untuk mengurangi biaya, meningkatkan kondisi lubang sumur dan integritas reservoir, dengan tetap mengutamakan kinerja keselamatan maksimum dan pemeliharaan lingkungan. Meskipun hasil akhir dari suatu operasi pengeboran mudah diamati, akan tetapi yang hampir sering luput dari perhatian adalah kompleksitas masalah dalam perencanaan dan pelaksanaan operasi Pengeboran. Dalam tulisan ini telah dievaluasi studi kasus pemboran eksplorasi di salah satu basin di Afrika Utara. Selama periode 2006 hingga 2011, peningkatan pengeboran yang berkelanjutan telah dicapai. Elemen kunci dalam optimasi tersebut meliputi fokus pada struktur manajemen team pemboran, perencanaan rekayasa/teknik sumur, perbaikan dalam pengelolaan operasi pemboran seperti praktek manajemen keselamatan di lokasi, dan juga analisis pasca pengeboran untuk mengimplementasikan pembelajaran untuk sumur berikutnya yang akan dibor. Hasilnya, selama pemboran 26 sumur selama tahun 2006 hingga 2011, hari pemboran berhasil dikurangi dari 87 hari (sumur pertama) menjadi rata-rata 40 hari, dengan kemampuan deliverable produksi sumur yang tinggi, juga kinerja catatan keselamatan yang sangat baik.

Abstract

Seeding is a process of mixing cement powder, water and additives that are then pumped into the well hole through the cover pipe to the annulus along the drilling hole. The success of a drill depends heavily on the success of the drill, so the calculation of the process of drilling is a very important thing to do in the milling industry. Data is obtained through field studies and library studies, then analyzed using casing diagrams and density tables, yields, and additive materials. The research phase included data collection, calculation of slurry volume, additive material calculation, and sack of cement calculation. The results of the research showed that the seeding process required a total volume of 27.55 bbl, with a composition of 98 sacks of grade G cement and 10.52 bbl of water. Additives used with the result included Silica Flour: 32.24 lb, Dispersant Liquid: 6.86 gall, Retarder Liqueid: 2.94 gall, Fluid Loss Control: 98 gall, Bonding Agent: 98 gal, and Defoamer Liquied: 2.94 gall. The equipment used in the sewing process includes the casing shoe, float shoes, casing collars, the float collar, and the shoe track. The research is aimed at ensuring that the seeding process runs smoothly and efficiently, as well as adding knowledge about the calculation of the volume of material required in casing seeding.
