    Drilling Technology and Costs existing geothermal well costs to make rough estimates of EGS drilling costs as a function of depth. Oil and gas well completion costs were studied to determine general trends in drilling costs. Research and development in EGS continues today with an EGS European Union project at Soultz, France, and an File Size: 2MB. It depends on a target depth, rate of penetration, and mission of the well. The geothermal well's D&C costs are higher than conventional oil and gas wells due to the larger diameter of the wells.

    Abstract Openhole logging tools have been used without wireline in memory logging for 20 years, in an important and growing market. A new system in field trials in Canada and Russia in further expands the operating envelope overlap between wireline and logging-while-drilling by making step changes in communications, autonomy, performance, and : Shawn Kupchenko, Neill Gilhooley, Sam Ash, Alyn Carrahar. @article{osti_, title = {Geophysical well logging operations and log analysis in Geothermal Well Desert Peak No. B}, author = {Sethi, D K and Fertl, W H}, abstractNote = {Geothermal Well Desert Peak No. B was logged by Dresser Atlas during April/May to a total depth of m ( ft).

Division of Geothermal. GEOTHERMAL WELL LOGGING AND TESTING by Pierre UNGEMACH 1. INTRODUCTION Logging and testing of geothermal wells are essential segments of any field exploration and development strategy addressing relevant reservoir engineering and resource management issues.

They constitute in deed a too vast domain, actually the substance of numerous books. As geothermal resources are considered renewable and can be used to generate baseload electricity while producing very low levels of greenhouse gas emissions, they can play a key role in future energy needs.

This book, edited by a highly respected expert, provides a comprehensive overview of the major aspects Book Edition: 1. RESEARCH AND DEVELOPMENT OF LOGGING TECHNOLOGY FOR DEEP GEOTHERMALRESOURCES, NEDO The development of two logging tools for deep geothermal resources was carried out by NEDO.

One is the PTSD (Pressure,Temperature, Spinner and Density of fluid) logging tool which uses a memory gauge and overcomes temperature effects associated with an electric logging cable.

Interpretation methods are relatively sophisticated in the petroleum industry. Principles and classification of well logging methods INTRODUCTION There are many different methods of well logging that can be employed for solving various problems connected with geophysical exploration (Singh, et al ).

These methods are based on different physical principles and have different operational techniques.

The primary purpose of this program is to expand access to the geothermal resource by reducing the cost of drilling and completing geothermal wells. This cost is typically two to five times that for an oil well of comparable depth, and well cost is usually about half the total capital investment for a geothermally-powered plant to generate Author: John Finger.

The Iceland Deep Drilling Project (IDDP) is a long-term program to improve the efficiency and economics of geothermal energy by harnessing Deep Unconventional Geothermal Resources (DUGR).

Abstract While traditional mudlogging techniques provide largely qualitative data, the prime objective of Advanced Mud Logging (AML) is to provide quantitative real time measurements in aid of a complete formation evaluation.

To achieve this, welCited by: 3. ogy, memory tools are now being developed to meet the needs of the oil exploration and geothermal indus- tries, and are capable of operation up to °C (Lysne, ).

Commercial memory tools to meet that specifi- cation are costly. The objectives for the present devel- opment were: to develop an inexpensive tool, using readily avail- able off-the-shelf electronic components and trans- ducers.

Rotary drilling is the most efficient technology applied in the oil and gas industry. It is a drilling technology that relies on continuous circular rotation of the bit to break rocks, while drilling fluids circulate through the bit and up the wellbore to the surface, making possible to drill safely and efficiently the well.

The Geothermal Log Interpretation Program at the Los Alamos Scientific Laboratory is charged with the development of log interpretation techniques to address geothermal problems. As part of this effort an assess- ment was made of potential benefits that might result from appli- cation of improved logging.

Research and Development (R&D) can improve geothermal drilling technologies in order to reduce its costs, but the main challenge today is to improve market conditions for geothermal deep drilling. However, the deep geothermal drilling market has still not been thoroughly assessed.
