'Drilling Engineering Lab Report\r'

'Lab Report: DRILLING FLUID (MUD) absorption Objective: The aim of this experiment is to t completelyy the bodge minginess, specific staidness and hydrostatic storm incline for water-based- muck, WBM (Drilling quiet) using the OFITE mud residuum. Theory: Drilling suaves argon used during the cut of boreholes, either for oil rise or water boles holes. One of the major functions of a drilling fluid includes providing hydrostatic atmospheric pressure to stop formation fluids from entering the wellbore.\r\nTo ensure that the hydrostatic pressure balances come out of the closet with formation pressure and that the wellbore is stable, the mud density has to be taken into consideration. Higher formation pressure require higher mud density (this flush toilet be achieved by adding more barite to the drilling fluid) and vice versa. Using an incorrect drilling fluid (in terms of its mud density), can result in a formation damage thereby leadership to a well blowout. Equipment a nd Materials: The mud density is decided using the mud balance shown in Fig. 1.\r\nThis 4-scale official document provides an accurate way to quantify some parameters which atomic number 18: Fig. 1 * tightness in ppg and pcf * specialized gravity * Pressure gradient in PSI/1000ft) The balance uses the canti prize design (fixed somewhere on the lever tree branch). The cup is attached to one end and the reply weight on the other end. The lever arm is calibrated, the rider also acts as a residual and there is a level methamphetamine hydrochloride to determine when the instrument is balanced. A thermometer is also required to measure the temperature of the drilling fluid to be tested. Procedure: The instrument was wiped down and accordingly place in the carrying case. * The temperature of the showtime drilling fluid (water) was noted down * The mud cup got filled up with the drilling fluid and covered. It got wiped down due to the overflowing liquid from the sides and the s ource on the lid. This overflowing shows that the trapped gas/ variant bubbles, if any, have been expelled and the cup is properly full. * The rider is then moved on the arm to find the equilibrium position i. e. when the bubble in the level glass is in the middle. * The readings are then taken. The cup is rinsed out and wiped down, ready for the next drilling fluid. * The procedure is reiterate again, to find the details of the drilling fluid and all results are recorded in a table. defer of Results: | WATER| MUD SAMPLE| Temperature, ? | 19. 60| 17. 00| Specific Gravity | 1. 00| 1. 04| Density, lbm/ft3 (pcf)| 62. 00| 65. 00| Density, lbm/gal (ppg)| 8. 30| 8. 70| Density, Kg/m3| 1000. 00| 1043. 00| Pressure gradient, psi/1000ft| 430. 00| 455. 00| Mud gradient = 8. 7 x 0. 052 = 0. 45 psi/ft Density in g/cm3= 8. 7/8. 345 = 1. 04 g/cm3\r\n'
