1. Voor running casing een veiligheids meeting waarbij alle betrokkenen aanwezig zijn. Vermeldt in Dagelijks rapport. R/U om casing te runnen. 2. Make up & pipelock shoetrack volgens de running lijst. Check casing floats (collar + shoe) na het inlaten van de eerste 2 joints. Weatherford installeer centralizers volgens programma. Run casing volgens running lijst. 13.3/8 ” Casing Running Programme

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

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

The following planning guidelines shall be adhered to: The casing tally (bottoms up) shall be made listing the pipe as when racked. Casing length shall be casing running length and not total length. The casing tally shall be checked by multiplying the number of joints to be run in the hole by the average length Casing and Liner Operations Planning

The centralisation of casing and liners as well as the correct positioning of the centralisers are essential parts of any casing or liner job. The main reason for centralisation is to ensure a homogeneous distribution of cement around the casing. No centralisation or poor centralisation will cause channelling of the cement and hence produce a Casing Centralisation

1. General Running Procedure 1. Visually check each joint of casing/liner to ensure all joints are clear of foreign matter, measured and drifted. Note: To prevent foreign matter entering the string whilst running it is necessary to: use a casing/liner cover where appropriate ensure dope is only applied to the pin end joint prior to Casing and Liner Running Procedures

This article describes the recommended guidelines for casing storage, handling and transport that need to be taken account in the design phase of the casing. 1 Storage The design of pipe racks is dependent on local conditions. i.e.: required load bearing capacity and degree of permanency. Racks can be made with pipe supports (stringers) set Casing Storage, Handling and Transport

Due to potential frequent changes to casing specification, casing make-up torque and drift dimensions shall be as per the manufacturer’s recommendations.           Buttress Thread Casing Connections 9.5/8 – 13.3/8 OD Casing (BTC) Make-up torque valves of buttress thread casing connections sizes 9.5/8in to 13.3/8in OD shall be determined by carefully noting the torque required to make Casing Make-Up Torque
