Innovative technologies to minimize well control issues caused by seepage to total lost circulation
Talk to an expertLost circulation is a common and costly challenge in drilling and cementing operations. It occurs when drilling fluid or cement slurry flows uncontrolled into formations with high permeability, fractures, or voids. During cementing, lost circulation can compromise zonal isolation, impede production, and lead to other expensive consequences.
Losses can occur due to natural geological formation features or fractures induced during drilling or cementing. Induced losses happen when the equivalent circulating density (ECD) exceeds the formation fracture pressure and causes the formation to crack. Understanding the root cause of the lost circulation event is critical to design a successful treatment.
We offer solutions for various loss scenarios that range from minor seepage losses to total losses. Before we tailor a treatment, it is important to understand the specific loss challenge. Considerations include loss rate, loss type (permeability, fractures, vugs, etc.), loss zone depth, formation permeability, and fracture size. By focusing on the unique aspects of each challenge, we deliver innovative and effective solutions.
We can help manage your toughest loss challenges and support your goal to achieve the required top of cement. Our approach integrates state-of-the-art digital twins, engineered fluids, and lost circulation materials to create customized LCM solutions.
Halliburton experts use Particle Wizard™ and Lost Circulation Wizard™ software during the job design and tailoring process. They strike a balance between the most effective LCM and fluids package to clear critical equipment dimensions and optimally seal the formation for its unique conditions.
