... with conventional well designs, in greenhouse gas emissions and other air emissions, and in harmful releases from manufacture of materials and chemicals and treatment of wastes. Relevant for operations outside European waters, the LCA shows that production and waste treatment of drilling fluid may pose...

... dioxide injection has been implemented in many different underground geological formations since the early 1970's as a means of enhancing oil recovery. CO 2 injection purely for emissions reduction is however relatively new. This paper aims to identify key differentiators between conventional well design...

... 30 - 40% of the overall development costs. Therefore the actual operational efficiency of the rig will have a significant impact on the overall project economics. During the initial stages of a project it is essential that the project requirements such as the regulatory requirements, well designs...

... with the others spread amongst cased hole, tripping and casing operations. The appendix describes case histories of kicks which illustrate important lessons to be learnt. For well designers:- ♦ anticipation of raised pressures in the reservoir from water injection; ♦ assuming the worst when drilling...

... been thoroughly tested and applied to numerous incidents. Having reached the position where a tool is now commercially available and is used extensively by practitioners, an evaluation of current Industry practice in the area of kick simulation for well design and kick management on the UKCS has been...

... Abstract This paper summarises the factors influencing the well design for a high pressure high temperature (HPHT) * field development using a Not Normally Manned Installation (NNMI) in the UK sector of the Central North Sea (CNS). drilling operation spe 30364 well design production...

... practicable hazard well design notification Introduction In his report into the Piper Alpha disaster, Lord Cullen recommended that responsibilities for offshore safety should transfer from the, then, Department of Energy (DEn) to the Health and Safety Executive (HSE). This was accomplished in 1981...

... or short radius drilling techniques. Development in the subsurface equipment for completion and repair of wells have also provided the means to optimize the well design and its subsequent production life time cycle. The industry is carefully implementing the above techniques and entering new business...
