Management procedure of the drilling wastes
(cuttings barns) recycling, generated during
production wells drilling in Surgil field
where: К 1 – factor considering degree of meteorological station security. It is defined according to
table 1 of Appendix 2 (“Instructions on calculation of evaporation from reservoirs surface”. L. Gidrometeoizdat,
1969). In our case, the factor considering degree of meteorological station security is
equal to 1.3;
К 2 – factor considering relief character in observation point of. It is defined according to table
2 of Appendix 2 (“Instructions on calculation of evaporation from reservoirs surface”. L. Gidrometeoizdat,
1969). In our case, the factor considering degree of meteorological station security is
equal to 1.0;
К 3 – factor considering average length of air stream speeding-up over reservoir at its various
security. It is defined according to table 3 of Appendix 2 (“Instructions on calculation of evaporation
from reservoirs surface”. L. Gidrometeoizdat, 1969). In our case, the factor considering degree
of meteorological station security is equal to 0.55;
v ф – wind speed at the height of weathercock for design period of time (month), m/s.
Conversion factor is calculated by formula:
r = (К х е п – е 200 ) / (е п – е 200 ), (P2.4)
where: К – factor considering relative reduction of steam tension over mud and depending on
chemical compound and concentration of dissolved substances. For binary mud the volume of factor
considering relative reduction of steam tension over mud is defined depending on the nature of
the dissolved substance, its concentration expressed in weight percent and temperature according to
Appendix 11 (“Instructions on calculation of evaporation from reservoirs surface”. L. Gidrometeoizdat,
1969). In our case, the factor considering relative reduction of steam tension over mud is
equal to 0.94.
calculations of water thickness evaporation from cuttings storages by months, carried out by
formulas P3.1-P3.4. by months are resulted in table P3.1.
