Abstract
Official abstract text for this publication.
One of the challenges of modern hydrocarbon production is the efficient sealing of a lost circulation zone. It has been discovered that it is possible to efficiently seal the fractures of lost circulation zones by formulating a fracture sealing composition based on a width of the fracture. In particular, it has been found that when the spurt loss volume is less than or equal to the fracture volume capacity of the fracture, then the sealing fluid can be pumped into the wellbore to form a sealing relationship with the fracture.
First claim
Opening claim text (preview).
What I claim is: 1. A method for improving wellbore pressure containment comprising: a) selecting a fracture sealing width of a fracture connecting to a wellbore in a formation; b) defining a particulate fracture sealing composition; c) determining a spurt loss volume for the fracture sealing width at different concentrations of the defined particulate fracture sealing composition in a fluid; d) evaluating a fracture volume capacity by:…
