Work Detail

Seismic Processing Services – Implementation Of Processing Services For 3D Seismic And Wide-Angle Seismic Measurements, Seismic Interpretation Of The Results And Digitization Of Geophysical Borehole Measurements. Swe Energie Gmbh (Swe E) Is A Company With A Majority Stake In The Stadtwerke Erfurt Group. As Part Of The Decarbonization Of The City Of Erfurts Central District Heating System, Swe E Is Examining Deep Geothermal Potential In The Erfurt Area. For This Purpose, Swe E Carried Out The Bmwe-Funded Project “Seismikeffizienz” Between February And June 2026 As Part Of The “Geoefficiency, Deep Geothermal Energy For Erfurt” Project. The Background To This Project Is That The Deep Subsurface In The Footwall Of The Thuringian Basin Is Completely Underexplored. The Exploration Target Is Crystalline And Can Be Assigned To The Area Of ​​The Central German Crystalline Zone (Mdkz). A Possible Deep Geothermal Reservoir Could Be Found In The Area Of ​​The Erfurt Fault Zone. Therefore, One Focus Of The Seismic Exploration Was To Search For Depth Disturbances Using A So-Called Wide-Angle Measurement. The Second Focus Was On The Areal Characterization Of The Transitional Floor And The Overburden To Optimize Drilling Planning. For This Purpose, A 3D Model Is Built. The Measuring Area Covered A Total Of 259.8 Km² (136 Km² 3D Seismic Plus 123.8 Km² Wide-Angle Measurement). 14,326 Excitation And 15,085 Reception Points Were Carried Out In The Main Measuring Area As Well As 4,722 Additional Reception Points For The Wide-Angle Measurement (Full Capacity: 19,576 Geophones Of The Inova Quantum Type). The Coverage Level Was Over 400 With A Bin Size Of 15 M X 15 M. The Total Raw Data Volume Is Approximately 92 Tb Of 3D Data And Approximately 6 Tb Of Wide-Angle Data. The Subject Of The Tender (Lot 2) Is The Processing And Seismic Interpretation Of The Data As Well As The Digitization Of Borehole Measurements. The Scope Of Services Includes In Particular: • Data Acquisition And Project Management, • Data Preparation And Preprocessing, • Standard Processing, • Common Reflection Surface Processing (Crs), • Pre-Stack Time Migration Including Velocity Modeling And Qc, • Pre-Stack Depth Migration, • Seismic Interpretation Of Layer Boundaries And Faults To Create A 3D Structural Model And • Digitization Of Borehole Measurements. The Bidder Must Submit A Technical Processing Concept (Max. 20 Pages) That Serves To Evaluate The Quality Of The Offer And Can Be Freely Designed In Its Presentation. In Particular, The Concept Must Comprehensibly Represent The Aforementioned Processing Steps As Well As The Seismic Interpretation Of The Data Set And Ensure The Best Possible Representation Of Steep Depth Faults As Well As A Reliable Velocity Model. Crs, Pre-Stack Time Migration And Pre-Stack Depth Migration Must Be Shown Separately In The Offer In Terms Of Functionality And Price. The Results Of The Individual Processing Steps, In Particular Standard Processing, Crs Processing, Pre-Stack Time Migration And Pre-Stack Depth Migration, Must Each Be Delivered As Independent, Documented Data Sets.
