Value Creation with Multi-Criteria Decision Making in Geosteering Operations
International Journal of Petroleum Technology, 2016, 3, 15-31 15 Value Creation with Multi-Criteria Decision Making in Geosteering Operations K. Kullawan1,*, R. B. Bratvold1 and J. E. Bickel2 1University of Stavanger, Department of Petroleum Engineering, 4036 Stavanger Norway 2Graduate Program in Operations Research, 1 University Station, C2200, The University of Texas at Austin, Austin, Texas, 78712-0292, USA Abstract: Due to escalated drilling costs, the petroleum industry has been attempting to access the largest possible hydrocarbon resources with the lowest achievable costs. Multiple well objectives are set prior to the start of drilling. Then, a geosteering approach is implemented to help operators achieve these objectives. A comprehensive literature survey has been performed on geosteering case histories, including many cases with multiple objectives. We found that the listed objectives are often conflicting and expressed in different measures. Furthermore, none of the cases from the reviewed literature has discussed a systematic approach for dealing with multiple objectives in geosteering contexts. Without implementing a well-structured approach, decision makers are likely to make judgments about the relative importance of each objective based on previous experiences or on approximate methods. Research shows that such decision-making approaches are unlikely to identify optimal courses of action. In this paper, we propose a systematic method for making multi-criteria decisions in geosteering context. The method is constructed such that it is applicable for real-time operations. Results show that different decision criteria can have significant impact on well success as measured by its trajectory, future production, cost, and operational efficiency. Keywords: Geosteering, real-time well placement, geosteering decision, multi-objective decision, decision making. -

ID: - 2767738 Automation Provides Unique Insights of The Rock Record and Subsurface Through the Delivery of a Robotic Sample Collection and Analysis Device David Tonner, Diversified Well Logging, Houston TX, USA, Aaron Swanson, Diversified Well Logging, Houston TX, USA, Ron Hollingshead, Diversified Well Logging Houston TX, USA, Simon Hughes, Diversified Well Logging Houston TX, USA , Stephen Seacrest, PetroLegacy Energy Austin TX, USA, Bret McDaniel PetroLegacy Energy Austin TX, USA ABSTRACT Abstract Objectives/Scope: From the very early days of oil and gas exploration, appraisal and development drilling, samples have been collected at the rig by mud logging personnel to conduct a preliminary geological analysis of the rock being drilled. This collection typically involves a sample collection recipient, board or bucket to collect a sample of rock over the desired interval. The sample is then sieved and cleaned in the appropriate way depending on the type of drilling fluid being used. As penetration rates have increased in some instances to more than 400 ft. / hr. the sample resolution has deteriorated exponentially. From an ergonomics perspective, the highest frequency to which a person onsite can collect a sample is once every 20 minutes. At 300 ft. / hr. this translates to 100 ft. of drilled rock. A new device has been developed and deployed which automates this manual process and thus ensures faster and more accurate collection of geological samples of the drilled rock interval. Sample resolutions of 5ft rock intervals have been attained at 400 ft./ hr. This technology has provided an important technological breakthrough and enables reduction of personnel at the rig site with a subsequent reduction in cost and HSE risk, particularly in areas of H2S. -
Common Practice of Formation Evaluation Program in Geothermal Drilling

During early exploration phase, the formation evaluation program is carried out by collecting as much subsurface information as possible. This was applied because of available subsurface data to support the development geothermal project are very limited. On the other hand, the program is very influenced and directly involve to the drilling operation that might risks the drilling operation, in term of well stability and well cost perspective. Thus, the effective and efficient techniques are highly required in the making of proper formation evaluation program. The main purpose of formation evaluation is to get a better understanding of subsurface geology and developed geothermal system so the best future strategy of field development can be determined. By doing this evaluation while drilling, it will give an advantage to the drilling operation itself. Knowledge of the real-time drilled formation, in term of its behavior, characteristic, and composition, will help the improvement of drilling performance and increase the well success ratio. -

Mud Logging – Rapid Analyses of Well Gases with an Agilent Micro GC
Mud Logging – Rapid Analyses of Well Gases with an Agilent Micro GC Application Note Oil and Gas Exploration, Mud Logging Author Remko van Loon Agilent Technologies, Inc. Abstract Oil and gas exploration operations require the analysis of dissolved natural gas in samples from the well within short run times. This application note addresses the use of an Agilent Micro GC for rapid, accurate mud logging analysis. Analytical test - ing of drilling fluid sample using the Agilent Micro GC has proven to be an excellent technique for analyzing individual hydrocarbon gases to assist with lithology reports for the mud logging field. The instrument's small form factor and low consumption of operating gas provides an ideal solution to incorporate into drilling operations. Introduction Table 1.

These are poorly understood. It is not uncommon to see as much as a measurements and information are gathered periodically on the ten-fold variation in mud gas response while drilling formations drilling rig. that have similar logs. Also, cumulative production has a poor Drilling parameters – or their proxies, such as string weight, correlation with mudlogging mud gas response in horizontal weight on bit, block height, drillstring length, pump strokes, wells. Mudlogging can be improved and more effective if we pump capacity per stroke, pump pressure, mud motor rotation, understand and account for the mud gas variations.
