Abstract: 1. A method for installing a tubular member axially through at least one over-pressured region of the earth, said tubular member having an upper end and a closed lower end, said method comprising the steps of: drilling a borehole to a depth proximate the top of, but not into, said over-pressured region of the earth; inserting said tubular member into said borehole, wherein said closed lower end of said tubular member is positioned proximate the top of said over-pressured region of the earth; inserting a filler material into at least a portion of said tubular member; and applying a force to said upper end of said tubular member, whereby an interval of said tubular member, including said lower end, is driven through said over-pressured region of the earth. 2. The method of Claim 1 wherein said closed end of said tubular member comprises a pre-installed grout plug. 3. The method of claim 1 wherein said filler material is a granular material. 4. The method of Claim 1 wherein said filler material is cement. 5. The method of Claim 4 further comprising allowing said cement to set-up prior to applying said force to said upper end of said tubular member. 6. The method of Claim 1 further comprising the step of drilling through said filler material and said closed lower end of said tubular member after said tubular member has been driven through said over-pressured region of the earth. 7. The method of Claim 1 wherein said tubular member comprises well casing, and wherein said method further comprises the step of installing a production tubing string inside said well casing after said tubular member has been driven through said over-pressured region of the earth, said production tubing string used for producing hydrocarbons from a subterranean reservoir located generally beneath said over-pressured region of the earth. 8. A method for installing a tubular member axially through at least one over-pressured region of the earth, said tubular member having an upper end and a closed lower end, said method comprising the steps of: drilling a borehole to a depth proximate the top of, but not into, said over-pressured region of the earth; inserting said tubular member into said borehole, wherein said closed lower end of said tubular member is positioned proximate the top of said over-pressured region of the earth; installing a force transmission means into said tubular member, said force transmission means extending from a distance above said upper end of said tubular member to a distance below said upper end of said tubular member; said force transmission means adapted to transmit a driving force from a point above said upper end of said tubular member to said lower end of said tubular member; and applying a driving force to said force transmission means, whereby an interval of said tubular member, including said lower end, is driven through said over-pressured region of said earth. 9. The method of Claim 8 wherein said force transmission means comprises a mandrel which is adapted to engage with a drive shoe means attached proximate said lower end of tubular member. 10. The method of Claim 8 wherein said lower end of said tubular member further includes a drive shoe means, and wherein said force transmission means is adapted to engage with said drive shoe means. 11. The method of Claim 8 wherein said lower end of said tubular member is closed by a closure plate. 12. The method of Claim 8 further comprising the steps of removing said force transmission means from said tubular member after applying said driving force to said force transmission means, and drilling through said closed lower end of said tubular member. 13. The method of Claim 12 wherein said tubular member comprises well casing, and wherein said method further comprises the step of installing a production tubing string inside said well casing after said tubular member has been driven through said over-pressured region of the earth, said production tubing string used for producing hydrocarbons from a subterranean reservoir located generally beneath said over-pressured region of the earth. 14. A method for installing a tubular member axially the earth, said tubular member having an upper end and a closed lower end, said method comprising the steps of: inserting said tubular member into the earth; inserting a filler material into at least a portion of said tubular member, whereby increasing the driving full resistance of said tubular member, and applying a force to said upper end of said tubular member, whereby the tubular member is additionally driven through the earth. 15. The method of Claim 14 wherein inserting a filler material into the upper portion of the upper end of said tubular member and said force is also applied to the filler material. 16. The method of Claim 14 wherein further comprising the steps of initial drilling a borehole through the earth and inserting said tubular element into said borehole. 17. The method of Claim 14 wherein said closed end of said tubular member comprises a pre-installed grout plug. 18. The method of claim 14, wherein said filler material is a granular material. 19. The method of Claim 14 wherein said filler material is cement. 20. The method of Claim 19 further comprising allowing said cement to set-up prior to applying said force to said upper end of said tubular member. 21. The method of Claim 14 further comprising the step of drilling through said filler material and said closed lower end of said tubular member after said tubular member has been driven to the aimed depth. 22. The method of Claim 14 wherein said tubular member comprises well casing, and wherein said method further comprises the step of installing a production tubing string inside said well casing after said tubular member has been driven through the earth, said production tubing string used for producing hydrocarbons from a subterranean reservoir. 23. The method of Claim 14 wherein said tubular member comprises a pile. 24. A method for installing a tubular member axially the earth, said tubular member having an upper end and a closed lower end, said method comprising the steps of: inserting said tubular member into the earth; installing a force transmission means into said tubular member, said force transmission means extending from a distance above said upper end of said tubular member to a distance below said upper end of said tubular member; said force transmission means adapted to transmit a driving force from a point above said upper end of said tubular member to said lower end of said tubular member, whereby increasing the driving full resistance of said tubular member. applying a force to said upper end of said tubular member, whereby the tubular member is additionally driven through the earth; removing the driving force means from said tubular element; drilling through said closed lower end of said tubular member. 25. The method of Claim 24 wherein further comprising the steps of initial drilling a borehole through the earth and inserting said tubular element into said borehole. 26. The method of Claim 24 wherein said force transmission means comprises a mandrel which is adapted to engage with a drive shoe means attached proximate said lower end of tubular member. 27. The method of Claim 24 wherein said lower end of said tubular member further includes a drive shoe means, and wherein said force transmission means is adapted to engage with said drive shoe means. 28. The method of Claim 24 wherein said lower end of said tubular member is closed by a closure plate. 29. The method of Claim 24 wherein said tubular member comprises well casing, and wherein said method further comprises the step of installing a production tubing string inside said well casing after said tubular member has been driven through the earth, said production tubing string used for producing hydrocarbons from a subterranean reservoir. 30. The method of Claim 24 wherein said tubular member comprises a pile.
