Safe-Shield Spacer enable operators to perform cement job with higher equivalent circulating densities (ECDs) without increasing the risk of formation break down and Safe-Shield LC4k is added to Safe-Shield Spacer systems to remediate against moderate, complete and total losses.
| Product | Description | Benefits | Applications |
|---|---|---|---|
| Safe-Shield Spacer | Safe-Shield Spacer is a Wellbore Guard Spacer for Cementing. | One sack solution, can be mixed on-the-fly with a weighted spacer. Enhances hole cleaning and mud removal prior to cement placement. Forms a shield against the formation to limit fluid invasion. Reduces formation damage from cement filtration or losses. Prevents cement fallback to achieve the desired TOC. Extends the frac gradient for higher ECDs. Density controllable and adjustable rheology. | For fragile, unconsolidated, and low fracture gradients formations. High-permeability formations. In wells where pre-job shows the ECD near or above the frac gradient. Ideal for wells with a narrow margin between fracture gradient and pore pressure gradient. |
| Safe-Shield LC4k | Safe-Shield LC4k is a Spacer Additive for Lost Circulation. | Improves the Safe-Shield Spacer system’s effectiveness when losses are challenging. Effective in sealing a wide range of fracture widths in various formations. Withstand differential pressures > 1,200 psi. Compatible with downhole accessories. Environmentally compliant for use in all areas. | Used during Partial to total lost circulation where fracture sizes between 10 to 4,000 microns. Used in high permeability formations, unconsolidated and fractured formations when losses were observed during the drilling phase. |
Product and customer insights
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.

AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
The East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
