Webb1 feb. 1982 · Summary. A one-well field test of nitrogen WAG (water alternating gas) injectivity was conducted to determine whether a reduction in water injectivity would occur after injection of nitrogen. A 40% reduction was observed immediately after nitrogen injection. Following three short WAG cycles, water injectivity increased to its pretest … WebbEXAMPLE STEP RATE TEST The following is an example of a Step-Rate Test with tabular and graphic results.
