Studi laboratorium perbandingan keefektifan serbuk gergaji dan pelepah pisang sebagai bahan kehilangan sirkulasi lumpur (LCM) dan pengaruhnya terhadap sifat rheologi lumpur air asin buatan
P Pada proses pemboran, Lumpur pemboran merupakan salah satu bagianyang memiliki peran sangat penting, mulai dari awal pemboran hingga pahat bormencapai kedalaman yang dituju serta menghindari kesulitan dan potensi masalahyang dapat timbul. Adapun kesulitan atau potensi masalah tersebut salah satunyaadalah kehilangan lumpur pemboran. Salah satu cara untuk mencegah danmenanggulangi kehilangan lumpur pemboran tersebut adalah denganmenggunakan media LCM.Berdasarkan hasil penelitian bahwa lumpur berbahan dasar air asin buatandengan penambahan pelepah pisang sebanyak 3 gram dam 5 gram pada sistem B1dan B2 memenuhi nilai spesifikasi saat temperatur 240oF. Pada sistem B1 densitas8.65 ppg, viskositas 76 second/quart, PV 20 cp, YP 15 cp, gel strength 10sec 4lb/100ft2, gel strength 10min 11 lb/100ft2, API water loss 30min 7.8 cc, mud cake1.4 mm dan pH filtrate 10.5.Pada sistem B2 dimana densitas 8.67 ppg, viskositas 85 second/quart, PV23 cp, YP 17 cp, gel strength 10sec 5 lb/100ft2, gel strength 10min 13 lb/100ft2,API water loss 30min 7.2 cc, mud cake 1.5 mm dan pH filtrate 10.3.Kesimpulan dari penelitian ini adalah, bahwa sistem lumpur B memenuhispesifikasi dimana nilai sifat fisik dan rheologi nya memenuhi standarlaboratorium. Sedangkan sistem A, sebagian besar tidak memenuhi spesifikasi.Dapat digaris bawahi bahwa sistem B atau pelepah pisang efektif dalammenangani lost circulation.
I In the process of drilling, drilling mud is one section that has a veryimportant role, from the start drilling until the drill reaches a depth chisel targetand avoid the difficulties and potential problems that may arise. As for thedifficulties or potential problems one of which is the loss of drilling mud. Oneway to prevent and cope with loss of drilling mud is by using LCM media.Based on the research that the mud made from artificial salt water with theaddition of banana skins as much as 3 grams 5 grams dam on the system B1 andB2 satisfy the specification value when the temperature 240oF. On systems B1density of 8.65 ppg, viscosity of 76 second / quart, PV 20 cp, YP 15 cp, gelstrength 10sec 4 lb / 100ft2, gel strength 10min 11 lb / 100ft2, API water loss30min 7.8 cc, mud cake 1.4 mm and pH 10.5 filtrate.In a system of B2 where the density of 8.67 ppg, viscosity of 85 second /quart, PV 23 cp, YP 17 cp, gel strength 10sec 5 lb / 100ft2, gel strength 10min 13lb / 100ft2, API water loss 30min 7.2 cc, mud cake 1.5 mm and filtrate pH 10.3.The conclusion from this study is that the mud system and meet thespecifications in which the value of physical and rheological properties it meetsthe standards laboratory. While the system A, the vast majority do not meetspecifications. Can be underlined that the system B or banana bark effective indealing with lost circulation.
