Erratum to: Production of Superlight Saraline Drill-In Fluid

  • Badrul Mohamed Yan Muhammad
  • Abdul Aziz Abdul Raman
Erratum

The name of the first author should be Badrul Mohamed Jan Muhammad.

In the title and throughout the article “drill-in fluid” should be replaced by “completion fluid.”

In the text of the paper “drilling” should be replaced by “perforating,” and “pressure differential” should be replaced by “underbalance.”

Figure 2 was inadvertently omitted from the article in the Russian version. It is here attached with its caption:
Fig. 2

a) Images of mixture separation at various amounts of homogenizing agent (stability of mixture less than 1 day). A) 1%; B) 3%; C) 5% w/w. b) Stable super lightweight completion fluid with homogenizing and stabilizing agents.

The second to the last paragraph on page 403 should read:

The results of determining the characteristics of fluids with different Saraline:GB ratios containing homogenizing and stabilizing agents are reported in Table 2. Addition of a homogenizing agent in the amount of 1–5 wt.% fluid (see Fig. 2a) with a Saraline:GB ratio of 75:25 reduces the viscosity of the mixture. This is because montmorillonite is the basic component (of the order of 90%) of the homogenizing agent, and in reacting with the glass bubbles, causes agglomeration of the mixture [8, 9]. The density of the mixture containing this agent increased, which decreased the underbalance in the wellbore. However, the stability of the mixture is very low (less than 1 day). A stabilizing agent must be added to obtain a stable fluid. Figure 2b shows the stable super lightweight completion fluid with homogenizing and stabilizing agents.
