Sikasil® WS-355 N | Weather Sealing

2021-12-29 · Sikasil® WS-355 N is a high-performance sealant suitable for jointing natural stone, such as marble, granite, sandstone and quartzite. With these materials, no staining of the joint edges occurs, unlike with conventional silicone sealants. Sikasil® WS-355 N is used for sealing facades, e.g. cladding of natural stone or other materials.

Sandstone Acidizing, GOM Field | Schlumberger

The sandstone acidizing experiments showed that a proposed mud acid blend (9/1.5 HCl:HF) increased the permeability of the perforated sandstone cores by about a factor of two. Surprisingly, comparable performance was obtained with the baseline acid currently used by the operator (10/10 HCl:acetic acid [HOAc]). The digital analysis of the tested ...
