A method of Determine a net pressure based on optimizing a waste injection process, the method including simulating a simulation formation based on input parameters, determining a closure pressure in crease per unit slurry volume based on the simulation, calculating a dis posal capacity of the selected formation, and outputting the disposal ca Determine closure pressure based on I pacity is also disclosed. simulation Calculate a disposal capacity based on the net pressure and the closure -/110 pressure Calculate time interval of cuttings re injection based on the calculated aW disposal capacity Output at least one of disposal capacity and time interval of cuttings I re-injection Figure 1 W O 2 0 0 9/10 5 3 3 0 A 3 ||IlIlII|IllV||lllIlllllIIl||II|||I||V|||||I||II|I||||II||II||||||||I|I|I|||||||||||| NZ, OM, PG, PH, PL, PT, RO, RS, RU, SC, SD, SE, SG' as to applicant's entitlement to apply for and be granted SK, SL, SM, ST, SV, SY, TJ, TM, TN, TR, TT, TZ, UA, a patent (Rule 4.17(ii)) UG, US, UZ, VC, VN, ZA, ZM, ZW. - as to the applicant's entitlement to claim the priority of (84) Designated States (unless otherwise indicated, for every the earlier application (Rule 4.1 7(iii)) kind of regional protection available): ARIPO (BW, GH, GM, KE, LS, MW, MZ, NA, SD, SL, SZ, TZ, UG, ZM, Published: ZW), Eurasian (AM, AZ, BY, KG, KZ, MD, RU, TJ, - with international search report (Art. 21(3)) TM), European (AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, Fl, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, - before the expiration of the time limit for amending the MC, MK, MT, NL, NO, PL, PT, RO, SE, SI, SK, TR), claims and to be republished in the event of receipt of OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, ML, amendments (Rule 48.2(h)) MR, NE, SN, TD, TG).
