Problem $1$

A four$-$point multirate isochronal test was performed on the

gas well in homework No$.3.$ The results of the test are

given in the table below.

Tasks

a$.$ Plot the backpressure $($or empirical$)$ curve.

What are the values for the backpressure exponent,

$n$ and the coefficient, $C?$

Is flow mostly laminar or turbulent?

b$.$ Plot the quadratic $($or theoretical$)$ curve using the Jones,

Blount & Glaze method.

What are the values of the coefficients a and $b?$

Assess the completion and if necessary, recommend

any remedial work to

improve the condition

of the well.
