Oil, Gas and Mining

Oilfield

LANDU Landercoll® is a vital additive in oilfield operations, designed to control fluid loss and adjust rheology in water-based oil-well servicing fluids. It delivers pseudoplastic flow properties, enhancing workability, suspension stability, and overall fluid performance in drilling, cementing, and completion processes—ensuring reliable and efficient results in demanding field conditions.

LANDU Hydroxyethyl Cellulose (HEC) for Oilfield Applications LANDU Hydroxyethyl Cellulose (HEC) is used to control fluid loss and rheology in oilfield applications, particularly in water-based oil-well servicing fluids. It exhibits pseudoplastic (shear-thinning) behavior, improving flow characteristics and suspension stability. HEC also enhances workability, making it a reliable additive for drilling, cementing, and completion operations.

Drilling & Completion/Workover

Drilling Process

Drilling fluid plays a crucial role in oil and gas exploration by performing several essential functions. It is used to transport drill cuttings to the surface, control subsurface pressure, and cool and lubricate the drill bit during operation. A well-formulated drilling fluid enhances drilling efficiency, safety, and equipment longevity.

Completion Process

In the completion phase, completion fluid is essential for maximizing production efficiency. It helps transport remaining cuttings and maintain the integrity of the wellbore, ensuring a clean, stable path for oil and gas flow. Proper use of completion fluid supports well productivity and long-term performance.

Cementing Process

During the cementing process, cementing fluid is used to protect the casing and prevent damage while sealing the wellbore. It fills the inside of the casing and blocks the inflow of formation fluids from the outside. In this application, LANDU HEC functions as an effective fluid loss additive, helping to minimize water phase loss, improve sealing efficiency, and ensure well integrity.

Fracturing Process

The fracturing process is a key step in shale gas extraction, where fracturing fluid is used to create and extend fractures in the reservoir rock. This allows proppants to be effectively transported into the wellbore, keeping the fractures open for gas flow. In this application, LANDU HEC acts as a rheology modifier, ensuring proper fluid viscosity and easy separation of proppants, enhancing the efficiency and control of the fracturing operation.
