Figure 4.7 – About pressure at the line injection

                  Injection  pressure  -  is  the  pressure  at  the  head  of  the
          water  injection  well  with  pumping  water  into  it.  In  practice
          waterflooding injection pressure ranges from 5 MPa to 16-20 MPa,
          and in some cases even 20-30 MPa and 40 MPa, accounting for an
          average of 13 MPa. The injection pressure should be greater than
