Abstract

E valuasi hasil penyemenan primer merupakan serangkaian kegiatan yang perlu dilakukan untuk mengetahui hasil penyemenan baik secara kualitatif maupun kuantitatif serta dari hasil evaluasi tersebut dapat di ambil keputusan perlu tidaknya dilakukan remedial cementing. Pada dasarnya, penyemenan dilakukan dengan tujuan memperkuat ikatan casing dengan formasi yang berguna untuk mengisolasi formasi dengan lubang sumur. Namun, tidak selalu penyemenan yang dilakukan bisa sempurna. Ada beberapa masalah yang sering terjadi, seperti channeling dan microannulus. Salah satu cara yang yang efektif untuk mendeteksi hadirnya channel dan microannulus pada semen adalah dengan menggunakan Segmented Bond Tool-Variable Density Log (SBT-VDL) yang merupakan jenis logging akustik dan mampu menganalisa secara kuantitatif maupun kualitatif. Evaluasi penyemenan primer dilakukan pada sumur M-13. Evaluasi hanya dilakukan dari interval kedalaman 165 ft - 1250 ft karena kemiringan sudut pada zona perforasi mencapai 73Âº sehingga alat SBT-VDL tidak dapat di operasikan. Analisa kualitatif SBT-VDL ditemukan adanya indikasi free pipe, medium cement dan poor cement, sedangkan dari kurvatransite time ditemukan adanya indikasi efek eccentering pada beberapa kedalaman. Analisa kuantitatif SBT bertujuan untuk menentukan bond ratio dan compressive strength setiap kedalaman.

E valuation of the results of theThe primary cementing evaluation performed on M-13 wells. The evaluation is only done from the interval of the depth of 165 ft-1250 ft due to the tilt angle in the perforation zone reached 73 degrees so that the perforation tool SBT-VDL cannot be running. Qualitative analysis of SBT-VDL found indication free pipe, medium cement, poor cement and the curve of transite time found indication effect of eccentering in some depth. Quantitative analysis of SBT aims to determine bond ratio and compressive strength in any depth. primary cementing is a series of activities that need to be done to find out the results of cementing good qualitative as well as quantitative as well as from the results of the evaluation can take decisions need not do remedial cementing. Cementing is basically held to strengthen the bond between casing and formation, which is useful to isolate formation and wellbore. Though, cementing doesnâ€™t always seem to be perfect. Some problems exist, such as channeling; the condition where cement fills only some parts between casing and wellbore. There are a variety of ways to evaluate the results of the cementing, One effective way to detect the existence of channel is by using Segmented Bond Tool - Variable Density Log (SBT-VDL), an acoustic logging which is able to analyze quantitatively and qualitatively.
