/B/Given data: Casing depth(3000 ft), Hole size(17.5-in).Casing(13.375-in OD,12.615-in ID,54.5 lb/ft). Drillpipe(5-in,19.5 lb/ft, 0.01776 bbl/ft).Pump(7-in- 12-in,Triplex at 95% eff, 0.136 bbl/st.).Shoe track (100 ft).Cementing program is neat cement(500 sks), yield slurry(1.15 ft/sk),Excess volume(50%). Determine: 1-Height of the cement in the annulus. 2-Volume of the cement in the casing. 3-Depth of the top of the cement in the annulus. 4-Number of barrels of mud required to displace the cement. 5-Number of strokes required to displace the cement.

Diameter (0.03m) of hole is doing by 1 point drill machine at cutting speed (60m/min), determine the spindle speed. The answer is; * 636*10-3 rpm 636619 rpm O 2636 rpm

A drillstring is composed of 9000 ft of 5-in 19.5-lbm/ft drillpipe and 1000 ft of drill collars having a 3.0-in. ID. COmpute the following items: a capacity of the drillpipe in barrels. b capacity of the drill collars in barrels. c. number of pump cycles required to pump surface mud to the bit. The pump is a duplex double-acting pump with 6-in liners, 2.5in rods, 16-in stokes and operates at a volumetric efficiency of 85%. d displace ment of the drillpipe in bbl/ft. e. displacement of the drill collars in bbl/ft. the OD of the collars is 8.0 in. f. loss in fluid level in the well if 10 stands of drill pipe are pulled without filling the hole. THe ID of the casing in the hole is 10.05 in. g. loss in fluid level in the well if one stand of drill collars is pulled without filling the hole. h,. change in fluid level in the pit if the pit is 8 ft wide and 20 ft long, assuming that the hole is filled after pulling 10 stands of drillpipe
