Abstract
Drilling mud have a very important role in a drilling operations, start over drilling until it reaches the depth of the intended. In the importance of drilling mud, therefore there should have an analysis of potential problems that might happen in the process of the drilling. The Problems that might happen in the process of drilling one of them is about the loss circulation. To overcome the problem of lost circulation mud , one example is a method of loss circulation material (LCM).There were different LCM category but in this study used Kwik seal and the midrib bananas as an ingredient LCM. Both of them have the fibrous having the nature of stiffness so it can clog the pores. In research was done three times experiment with the additional kwik seal and adding different banana midrib .This study using specification of physical properties and rheology standard of a mud field drilling to get results like the environment actually on the ground .The results of research is expected us to know how much composition kwik seal or the midrib bananas to be added to the mud and effective to overcome lost circulation .

Abstract
Ruhoul is an offshore gas field that located in Mahakam Delta, East Kalimantan, Indonesia. It covers an area of 350 km2 and has a gross thickness of the payzone over 2000 m. Structural architecture of Ruhoul field is multilayered un-faulted anticline. Stratighraphycally, Ruhoul reservoirs are divided into two intervals which are Ruhoul Main Zone and Ruhoul Shallow. This study is only focused in Shallow zone area, they are Sh-8a, Sh-8c, and Sh-8d, as it is considered as remaining prospective area for Ruhoul field. For more specific, Sh-8a was produced by wells RJ-16A-M and RJ-2G-M.T3, Sh-8c was produced by well RJ-2G-M.T3, and Sh-8d was produced by well RJ-2G-M-T3. Over time, the gas production in Ruhoul Field keep decreasing, therefore hidden gas production potential needs to be re-evaluated. The evaluation can be done by doing the dynamic synthesis analysis based on completion type used, production history, and well correlation. The main objective of this study is to evaluate hydrocarbon potential in Ruhoul Shallow specific area. Several approaches will be used to assess Ruhoul Shallow zone prospect such an updated database, zone change inventory, and well correlation based on netpay map by layer with software Geolog 7.2. Perform Dynamic Synthesis Analysis and P/Z Straight Line Material Balance Calculation are chosen as the methodology to assess the prospect zone of this field. The results of this process are candidates to be the re-opening zone, the value of GIIP, EUR, RR, RF, the drive mechanism, and plateau rate stage that applied to each layer. The candidate layer to open is Sh-8a at RJ-2G-MT3 and GIIP is 1.1517 Bscf.
