There are a number of areas in horizontal well casing design that may differ from a standard well. These mostly relate to the casing loading, although there can be instances where the capacity of the casing is purposely reduced. Casing loading Fpr the horizontal section itself, the stability of the formation must be determined in … Horizontal well
Casing is one of the most critical well consumables with respect to timing. Total elapsed time for procurement of Oil Country Tubular Goods (OCTGs) varies from 6-18 months. This includes tendering procedures, placing of the purchase order, manufacturing and delivery to the required location. 1 Timing Normal deliver-time from a mill once an order has … Ordering casing
The burst, collapse and axial strengths of casing are directly related to wall thickness, and hence are reduced by wear. The casing must be designed so that wear will not reduce the strength of the casing below that which will enable the well to be drilled and operated safely and efficiently. 1 Introduction Unless there … Influence of wear on casing strength
Ditch Magnets The metal worn away from the casing and tooljoint is carried by the mud to the shaker header box where it will be attracted to the ditch magnet. Not all the metal particles will be trapped and so the amount of metal cannot be used as an exact quantitative measurement of metal worn … Monitoring Casing Wear
1. Hold safety meeting with crews before starting running the liner and report in iadc. 2. Make up plug dropping head on drifted single and lay in v door. Prepare 10m of chicksan lines. 3. Make up and bakerlock shoe track. Test floating equipment Make up torques: Min ft.lbs Opt ft.lbs Max ft.lbs Rih 4 … 4 1/2″ Liner running programme
In High Presure High Temperature (HPHT) environments, high differential pressures often lead to the use of high strength, thick-walled, and occasionally non-standard, casing. High temperatures compound the design problem by reducing the yield strength of the casing steel, by causing significant thermal linear expansion of the steel, and by generating high pressures in sealed annuli … HPHT well
Tie-back packers are generally run in the following circumstances: – an inflow test has been performed and has failed – the CBL indicates that a hydrocarbon bearing interval is poorly isolated from the liner lap – time savings are envisaged. In this case the packer could be run integrally with the liner hanger. The inflow … Tie-Back Packers – General Information
In the detailed design phase, the casing designer determines the material grade and casing wall thickness for each section of the casing scheme selected, which will allow it to withstand all realistically expected loads throughout the life of the well. Selection of relevant load cases Before design calculations can be performed for a given casing … Detailed Design and Analysis
This article describes the uniaxial collapse, burst, axial and compression design factors, and the triaxial design factor, recommended for use, together with a brief overview of the considerations which led to the choice of the generally accepted values. Each uniaxial design factor is defined as the minimum ratio required between the corresponding casing strength tabulated … Casing design factors
