Abstract
A method for determining distribution data for a disposal domain parameter to increase assurance in a cuttings injection process, including performing a fracturing simulation using a site specific datum to obtain a fracturing result, determining a probability of creating a new fracture using the fracturing result and a probability model, performing a plurality of fracturing simulations using the probability and a distribution associated with the probability to obtain disposal domain information, and extracting the distribution data for the disposal domain parameter from the disposal domain information.
Claims16
A method of determining disposal domain information for a cuttings injection process at a site, comprising:
- performing a first fracturing simulation using a site specific datum to obtain a first fracturing result;
- determining a probability of creating a new fracture in a formation at the site using the first fracturing result and a probability model;
- performing a plurality of fracturing simulations to obtain the disposal domain information, wherein the performing a plurality of fracturing simulations comprises:
- assigning a type of distribution for the probability of creating the new fracture in the formation at the site,
- selecting a first value for the probability of creating the new fracture in the formation at the site using the type of distribution
- running a second fracturing simulation using the first value as input to obtain a second fracturing result, wherein the second fracturing simulation is one of the plurality of fracturing simulations, and
- determining the disposal domain information using the second fracturing result;
- and
- generating an operational parameter for the cuttings injection process at the site using the disposal domain information.
