Tenders Are Invited For Drilling And Exploration Work - Construction Of The Kruszwica Gt - 1 Geothermal Well For The Exploration Of Thermal Water Resources From The Lower Jurassic Formations In The Kruszwica Area

Drilling And Exploration Work - Construction Of The Kruszwica Gt - 1 Geothermal Well For The Exploration Of Thermal Water Resources From The Lower Jurassic Formations In The Kruszwica Area. 1. The Subject Of The Order Is The Construction Of The Kruszwica Gt-1 Geothermal Well For The Exploration Of Thermal Water Resources From The Lower Jurassic Formations In The Kruszwica Area. The Aim Of The Works Is To Search For And Recognize Thermal Waters In The Lower Jurassic And, Optionally, Lower Cretaceous Formations By Drilling The Kruszwica Gt-1 Exploration And Appraisal Well In The Area Of ​​Kruszwica. The Order Includes Drilling Of The Kruszwica Gt-1 Exploration And Appraisal Vertical Geothermal Well To A Designed Depth Of 3,290 M (±10%). The Borehole Is Assumed To Enter The Ceiling Of The Lower Jurassic Deposits At A Depth Of Approximately 2,750 M. Geological Supervision Will Constantly Correct The Assumptions Of The Geological Works Project In Terms Of The Depth Of The Borehole (In Relation To The Project Assumptions), The Structure Of The Borehole, The Piping System And Sampling. The Exact Method Of Filtering And The Depth Of Foundation Of Individual Pipe Columns Will Be Determined By The Geological Supervision In Consultation With The Plant Operations Manager, Based On The Obtained Test Results And The Geological Situation In The Well. The Subject Of The Order Includes All Works Necessary For The Proper Drilling Of A Geothermal Well, Enabling The Ordering Party To Obtain Optimal Parameters Of The Thermal Water Intake, In Particular: A) Preparation Of The Operation Plan As Well As All Necessary Documents And Studies For The Proper Execution Of The Borehole And Geological Works; B) Obtaining, Before The Commencement Of Works, All Decisions And Permits Necessary To Commence Geological Works, In Particular The Decision Of The Territorially Competent Director Of The District Mining Office Approving The Traffic Plan For Drilling A Drilling Hole And Geological Works; C) Carrying Out Preparatory Work (Protecting The Area Against Possible Technological Leaks And The Negative Impact Of The Drilling Process, Preparing The Site And The Drilling Areas Facilities, Installing Devices And Installations, Equipment And Supplies, Supplying The Construction Site With Utilities: Energy, Water And Sewage Collection, Construction Of A Temporary Discharge Water Tank, Etc.); D) Construction Of A Vertical Geothermal Hole With A Depth Of 3290 (+/- 10%) M, Installation Of The Hole Structure (Pipe Columns: 24, 18 5/8, 13 3/8, 9 5/8 And Filter Column 6 5/8), Reinforcement Of The Hole Outlet; E) Performing Geophysical (Downhole) Tests After Completion Of Each Section Of The Hole (Diameter And Curvature Of The Hole, Lithological And Stratigraphic Profile Of The Hole, Dip Of Layers, Permeable Intervals Within The Formations Of The Deposit Zone, Condition Of Cementation Of Casing Pipes), Production Log Test For The Deposit Zone, Measurement Of Temperature Distribution In The Hole For The Entire Hole; F) Sampling Of Crumbs And Cores While Drilling The Hole, As Well As Sampling Of Water And Gases From The Deposit Zone; G) Delivery And Installation Of A Submersible Pump; H) Performing Cleansing Pumping; I) Carrying Out Hydrogeological Tests (Hydrodynamic Tests - Three Levels Of Efficiency); J) Performance Of Work Related To Completion
