Landercoll™ HEC is used by the oil and gas industry for various applications such as rheology modification in fluids for drilling and completion of petroleum and natural gas wells.
Furthermore, Landercoll™ is used in hydraulic fracturing processes and it is an effective fluid-loss additive in well cements. Landercoll™ HEC is compatible with most additives such as biocides, antifoaming agents, oxygen scavengers, fluid loss control additives and retarders. As a naturally derived polymer, it is easily biodegradable.
Wells are often expected to produce hydrocarbons for a long period of time, which is only achievable with proper cementations of the well casing.
Landercoll™ products provide the following properties for the oil and gas industry:
l Rheology modification
l High salt tolerance
l Fluid loss minimization
l Clear Solution
Furthermore, Landercoll™ HEC as a naturally derived polymer, is easily biodegradable.
The choice of Landercoll™ types depends on the application and the requirements, the most commonly used types are Landercoll™ H and Landercoll™ HT grades.
