“…Its greater purpose is to address the challenges created by wellbore environments. These challenges Include deploying tools at the surface, overcoming frictional forces, maneuvering past obstacles, and adapting to unforeseen downhole conditions [5]. Conveyance methods can be grouped into two basic types: cable conveyed and pipe conveyed.…”

This review work summarised new generation logging techniques such Tough Logging Conditions (TLC) & Logging While Fishing (LWF) and their advancement in drilling operations. The production of Oil & gas from the stage of exploration to production should need a lot of data for economic and safe operations. The conditions of the sub-surface cannot be simply predicted unless with some measured parameters under the LOGGING term. Logging is defined as a continuous record of Petro’s physical parameters of rock against time and depth. Instead of conventional logging techniques of wireline such as SP, Gamma-ray, Neutron, Calliper log, etc, logging while drilling, logging while fishing set them aside of their extended applications. Logging while Fishing is a new generation technology that allows unfailing operations of logging tool by a special installation even in cut and thread operation also aids economic and time enhancement. Tough logging conditions are a technique applied either when the hole has highly deviated or when you need to control the position of a tool. This project includes the study and interpretation of above discussed new generation logs. These tools offer all types of logging carried out on wireline except the SP logging. Logging while drilling provides real-time measurements of physical parameters while drilling operation itself which avoids an additional running of tools causing trips and sticking of drill pipe. The data is stored in the bottom assembled logging tool.

“…Jenis gas asam atau sour gas ini memiliki efek dan bahaya terhadap lingkungan yang perlu diberikan perhatian dan perlakuan khusus, mengingat sour gas memiliki kandungan hydrogen sulfide (H2S), carbon dioxide (CO2) yang cukup tinggi. Kondisi sour gas perlu dipertimbangkan dalam desain komplesi dan desain operasi komplesi yang aman dan tepat untuk menghindari bahaya kandungan sour gas tersebut (Haris, A., et al, 2012). Desain komplesi secara konseptual bertujuan untuk memastikan semua parameter baik parameter sumuran, kondisi fluida yang mengalir terhadap kemungkinan korosifitas, pH lingkungan sumur, lingkungan sekitar sumur menjadi − 2 − pertimbangan jika terjadi kegagalan desain dan tentunya keekonomian dari sumur tersebut (NORSOK M-001, Rev 3, 2002).…”

AbstrakDesain komplesi harus mempertimbangkan beberapa parameter dari sumur, meliputi tekanan, temperatur, jenis fluida yang diproduksikan dan laju alir produksi sumur tersebut, dimana desain harus tahan terhadap beban yang dapat terjadi selama usia sumur. Jenis fluida yang dihasilkan berperan penting dalam pemilihan material, terutama untuk gas asam yang mengandung konsentrasi H2S dan CO2 yang tinggi. Analisa pemilihan material tubing, jenis packer dan aksesoris pelengkap dianggap perlu untuk memastikan bahwa material dan desain dapat menahan semua beban yang mungkin terjadi selama usia sumur.Setelah desain secara konseptual ditentukan, maka desain detail secara keteknikan dapat dilakukan. Pemilihan material dan desian komplesi sumur didasarkan pada kondisi sumuran dengan menggunakan beberapa metode, seperti stress analysis, triaxial stress analysis dan tubing movement analysis. Material yang terpilih kemudian diuji dengan kondisi masa produksi sumur dan selama tahap instalasi untuk melihat integritas sistem. Tubing 25CRW-80, Retrievable Packer dengan long locator seal bore complete with Perfluoro Elastomers, Tubing Retrievable SCSSV (Surface Controlled Sub-Surface Safety Valve) dan 25CR aksesoris komplesi dapat menahan semua kemungkinan beban selama siklus dan usia sumur.Kata kunci: gas asam, desain, komplesi, material. AbstractWell completion design is an important aspect in oil or gas well before the production phase. Completion design should consider some crucial parameters of the well including pressure, temperature, type of produced fluid and the flow rate of the well, where the design should last and overcome all of disturbance that migh occurs during well life cycle. The type of produced fluid plays an important roles in material selection, especially for sour gas that contains high concentration of H2S and CO2. Analyzing the tubing material selection, type of packer and completion accessories is considered necessary to ensure that the materials and design could withstand all the loads during well life. After conceptual completion design is define, then detailed engineering design is proceed. Material selection and completion design is based on the condition of the well by using several methods, such as stress analysis, triaxial stress analysis and tubing movement analysis. The selected materials then tested by the well production condition and during the installation phase to see the integration of the system. Tubing 25CRW-80, Retrievable Packer with long locator seal bore complete with Perfluoro Elastomers, Tubing Retrievable SCSSV (Surface Controlled Sub-Surface Safety Valve) and 25CR completion accessories could withstand all load possibilities for the well life cycle.Keywords: Sour Gas, Completion, Design, Material.

“…Semakin tua suatu lapangan migas, umumnya akan terjadi peningkatan kepadatan penduduk disekitar lokasi sumur, semakin sulitnya akses ke lokasi sumur yang semakin padat, dan semakin terbatasnya buffer zone di sekitar lokasi sumur, dan lainnya. Berbagai hal tersebut menambah kompleksitas operasi sumur, kerja ulang (Haris, A., et al, 2012) dan tentunya abandonment pada akhir usia sumur.…”

Oil was explored and found by Royal Dutch (Shell Group) geologist in early 1900. And since Indonesia’s independence, development in oil and gas projects was able to put Indonesia as one of major oil exporter country with daily production above 1 Million barrel per day in 1970 – 1990. With time as fields become mature, some of the fields have come to the end of its life cycle, where mostly 70% of Indonesia total old oil wells will have no economic value and has to be permanently Plug and Abandonment (P&A) as ruled by the government. It’s part of decommissioning an entire field with environmental preservation which called Abandonment and Site Restoration (ASR). As P&A will impact operating company investment as outlined in Ministry of Energy and Mineral Resources (ESDM) No. 15, 2008, efficient P&A operation should be evaluated to ensure proper planning and executions. The subject of evaluation is X well located onshore at Y Field, Java, Indonesia. P&A operation with multiple cements plugs as barriers to ensure no fluids migrations from one formation to others, or to surface. Evaluation between workover rig and rigless P&A operation with coiled tubing unit (CTU) and electric line (E-line) will be presented in this paper to value the expenditures and achieving the result as standardize by the government with accordance of operating company standard. Results show that rigless operation is the preferable solution, which lead to cost effective operation. Rigless operation saves 25% of P&A operations even tough with longer operation days.
