- W1963965910 abstract "Abstract For those who are familiar with the financial risks, it is very clear that showing a profit is not an easy task for a small turnkey drilling company. In fact, a small mis-step could spell disaster for a small turnkey contractor. This is an undeniable fact. It is also true that both Major Operators and Independents alike are sensitive to drilling bid prices even during times of prosperity and favorable oil and gas prices. Beating down the turnkey prices often, in some quarters, is considered a good sport. What must a small turnkey contractor do then? In order to meet the challenge of profitability for a small turnkey operator, the author introduced a simple Modular Drilling Fluid System that solved many costly problems. The Modular Drilling Fluid System, in nearly 70 wells, eliminated the gumbo problem and cut the drilling days by 20 to 50 percent. The reduction of drilling days, to the contractor, meant increased bit life by as much as 30 percent, savings in fuel costs by about 30 percent, savings in rig repair cost by about 30 percent, and a host of other savings. In this paper, in his comparative analysis, the author examines the bit records and other pertinent field data from three wells drilled in the same field and discusseses the principles of a modern Modular Drilling Fluid System that allowed a small turnkey contractor to become financially and technically successful. Furthermore, for analyzing the efficiency of the operational parameters such as bit hydraulics, weight on the bit, and rotary speed of the same small turnkey rig that drilled the above-mentioned wells, the author uses the simple yet powerful principles of Minimum Energy. This is done in order to quickly and easily point out where it is possible to save on the expenses of the small turnkey contractor. In this method, although more emphasis has been placed on hydraulic and mechanical energy, or power, all of the expended energies or powers of the rig system can be integrated over time. Applying a modified form of a combination of Lagrangian and Hamiltonian Integral1-7 carries out this process. The operational performance of the turnkey drill rig is said to be efficient when the value of this Integral is at a Minimum in comparison with the performance of the other drill rigs, or zero ideally. This technique enables the contractor to closely monitor his daily operational expenditure of Energy or Power and succeed both technologically and financially." @default.
