DRILLTEC GUT GMBH

Based on experience of the execution of deep geothermal wells and the implementation of innovative technologies DrillTec has become a well-known partner of the E&P, Geothermal and other drilling related industry. DrillTec’s range of services includes:


  • Drilling of wells for hydrocarbons, geothermal and gas storage wells

  • Coordination and additional drilling services: e.g. pipe installation, casing drilling and supply of BHA components

  • Complex workover and abandonment services

  • Engineering services: planning, studies, local authorities procedures, personnel recruiting, drilling documentation including entire project management (EPC)


The operated drilling rigs are compact and modularly assembled and designed for high mobility and optimal transport. They are equipped with modern drilling software, enable a minimal visual interference because of low height, can be driven by generators as well as by power supply from grid and are suitable for cluster projects and geothermal wells because of their innovative skidding systems. Their high level of automation and safety standard (SIL) and their field proven pipe-handling systems are essential parts of the rigs. Our rigs are manufactured in-house and enable a flexible reaction on market requirements including innovative solutions for new technical developments.

DYNAFLOW RESEARCH GROUP

Dynaflow Research Group (DRG) offers high quality engineering services ranging from the typical to the most complex and critical technical issues in the field of mechanics and flow. Since the earliest developments in pressurized fiberglass reinforced piping (FRP) took place in the middle east around the 1980’s, DRG has had a strong presence in the design, analysis and third- party review of FRP systems. DRG is consulted by a multitude of parties among which are pipe manufacturers, EPC contractors as well as operators. DRG is a leading technical member of the ISO 14692 committee since its installment and participates in other committees such as the DNV committee for certification of fiberglass craftsmanship and the ISO TC6 WG5 committee

that is working to produce a standard that regards above ground non-tensile resistant FRP piping.


DRG also provides engineering services in the area of engineering design (cooling water- and firewater piping systems, pressure vessel design, boilers, tanks), failure analysis, due diligence studies, component design and manufacturing support.

Sand Screen applications for water wells


For a large potable water project in North Africa, Fiber Reinforced Plastic composites have been applied for the well casings and sand screens. Water wells drilled in the mountains transport fresh water over a long distance to urban areas. The FRP was used as an alternative for conventional carbon steel materials that are inherently prone to corrosion. DRG carried out design reviews of potential sand screen options for this project

Experts in (downhole) flow analysis

DRG has a thorough understanding of the physics behind the fluid flow phenomena and much experience with pipeline engineering. By combining its expertise in fluid flow behavior, dynamic oscillations, FEA and CFD analysis, DRG solves the most technically challenging problems for its clients.


Studies using fluid flow modelling including Computer Fluid Dynamics has been used in a number of well technology optimization projects. Examples are: A study to predict displacement efficiency of a fluid displacement method used to seal wells; and a force prediction - and optimization study of a novel directional drilling tool.

Piping for CO2 storage


For an underground CO2 storage in the Netherlands DRG carried out the engineering/design of the FRP piping system. CO2 is highly corrosive and FRP is an excellent alternative for steel options.


Geothermal well project in the Netherlands


Also for above ground piping, FRP is often used as a corrosion resistant alternative for conventional steel piping. For a geothermal well project in the Netherlands, DRG carried out the design of the above ground FRP piping to transport the (corrosive) water of the production well to the heat exchangers.

Training and Education


DRG offers an extensive (online) training program that comprise static and dynamic stress analysis of (fiberglass) piping, pressure vessel design, fluid flow and programming languages.

 

CLAUSTHAL UNIVERSITY OF TECHNOLOGY (TUC)

The Institute of Subsurface Energy Systems (ITE) at Clausthal University of Technology, Germany, was founded in 1943. Its Drilling and Production department has its focus on drilling technology, well integrity and production optimization. The institute has intensified its research and development efforts in the area of geothermal energy in the past decade. A number of projects are conducted addressing essential challenges in drilling geothermal wells as well as during the production phase aiming to reduce investment and operating cost for geothermal energy.


ITE disposes of several laboratories covering all major research fields in subsurface energy systems. One of the department’s most distinguished and unique facilities is the certified OCTG (oil country tubular goods) testing center, in which full scale pipes are exposed to all relevant types of loads according to API and ISO standards, resembling real operating conditions. Simultaneously, the outstanding expertise and technical equipment allows for fundamental research and development of new pipe materials, connections and full scale equipment. In regard to the current project, new testing techniques and procedures will be developed oriented towards glass fiber reinforced epoxy casing strings.

EARTHA

Eartha is a one-person firm providing technical consultancy services for the development of geothermal energy projects worldwide focusing on:
• Reservoir engineering
• Well test engineering
• Project Coordinator
• Technical Due Diligence / Feasibility Studies

Eartha develops DRGmic reservoir simulations for green fields to evaluate the well operating parameters, the response of the reservoir to various exploitation strategies, and resource design criteria for sizing the power plant capacity and its design point for inlet pressure, mass and temperature. And as well for mature (more than 10 year production history), large (wellfield of more than 100 wells) and complex geothermal projects (interference of geothermal neighbours) with the objective to evaluate and to forecast the response of the reservoir to production and injection of the geothermal fluids, to plan make-up wells, and mitigate reservoir performance decline caused by lack of pressure support and/or cooling.
Eartha also excels in coordination of geoscience and design engineering teams for the integration of resource assessment and development, and design criteria for gathering and injection system and power plant. Scope of services include assessment of the technical constraints provided by the geochemical characteristics of the geothermal reservoir fluid and gasses and its impact on well operating conditions, material compatibility, technical and chemical mitigation strategies to prevent or inhibit scale and corrosion reactions respectively. In addition, Eartha is competent in providing in-depth technical advisory to geothermal investors about the presented project and the available resource data room, and the technical implications of projected financial models of a future geothermal project.
