5 m3 per well-job in average were performed in 10 steam huff-puff wells from March 2007 to March 2008 and 9 operations were successful in that the oil output rose and the water production dropped notably in a period exceeded the production cycle in some cases.

This SDA was successfully used in two steam huff-puff wells with 8 and 10 m3 of working fluid injected per well.

This combinational clay stabilizer in 10% aqueous solution was successfully used in antiswelling treatments of steam huff-puff wells at Gudao 24 well-times with treating radius being in range 1.

During exploiting heavy oil in steam huff-puff production wells, Electric cables are usually used to heat produced liquid.

Resin-coated sand FSJ-Ⅴ for sand control in steam huff-puff production wells is prepared from a commercial bor-containing phenolic resin, FB, an amine containing curing agent, quartz sand of particle size 0.
