  Geothermal associate

  Project 1:Jawa-Bali Geothermal Prospect Evaluation for PertaminaEvaluate 71 prospects in Java and 5 prospects in Bali based on geology, geochemistry and geophysics data to produce conceptual model and resource/reserve estimation.Project 2:Sibayak, North Sumatra Economic Feasibility StudySimulate reservoir with wellbore analysis and technical resource data (PT survey data) to get the Power output. Cost and Benefit analysis of several scenarios on the development result data. The conclusion is the best development scenario.Project 3:Sibayak, North Sumatra Development EvaluationEvaluate Sibayak field base on Pressure-Temperature logging data. Simulate wellbore to predict the wellbore behavior on standard hole and big holes. And giving a suggestion about what is the best development scenario regarding reservoir pressuresProject 4:Non Productive Time Identification for Pertamina Geothermal DrillingWith a team, we identify nonproductive time identification for a drilling campaign. Using daily drilling reports, composite log reports, mud logging, bit records, drilling time charts and the general data, we generate an evaluation.Project 5:Underbalance Drilling Screening Assessment at “X” geothermal field.I apply a method to determine whether the underbalance drilling is feasible or not. It is based on wellbore stability, loss circulation, reservoir damage, stuck-pipe incident, hard drilling and cost benefit calculation. Project 6:Bottom Hole Press. & Hole Cleaning calculation at a drilling campaign.I calculate the bottom hole pressure as a function of drilling mud properties and the pressure loss that occur along with it. Also calculating the minimum velocity to clean a hole based on aerated underbalance drilling campaign. Show less
