Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drilling operations lack efficient multi-domain planning and control systems that integrate real-time data from various drilling phases and environments, leading to suboptimal resource field development and increased operational risks.
Innovation Solution
A multi-domain planning controller that utilizes compiled multi-domain code to issue calls to a planning domain definition language planner, receiving and dispatching actions for physical operations, integrating with a system that includes processors, memory, and computer-executable instructions for real-time decision-making and action dispatching across multiple domains.

Engineering Contradiction Analysis
1Productivity
If traditional drilling control systems are used, then system simplicity is maintained, but operational efficiency and decision-making precision deteriorate due to lack of real-time multi-domain integration
Solution Approach 1:
The control system is segmented into multiple independent planning domains (e.g., drilling domain, completion domain, workover domain), each handled by separate PDDL planners. This allows real-time multi-domain planning without requiring a monolithic complex system, as each domain can be processed independently while maintaining overall integration through the common runtime environment.
Solution Approach 2:
The PDDL planning framework provides universal functionality across multiple drilling domains. The same planning infrastructure supports different operational phases (drilling, completion, workover) and various equipment types, reducing overall system complexity while enabling comprehensive real-time control across all domains.
2Measurement precision
If real-time multi-domain planning is implemented, then decision-making precision is improved, but computational time and processing complexity worsen
Solution Approach 1:
By dividing the planning problem into separate domains with dedicated PDDL planners, the computational burden is distributed rather than concentrated. Each planner processes only its specific domain's data and constraints, enabling real-time decision-making precision without requiring excessive computational time for a single monolithic analysis.
Solution Approach 2:
The system uses pre-compiled multi-domain code and pre-defined PDDL domain specifications that are prepared in advance. This preliminary preparation of planning frameworks and domain models allows the runtime system to execute decisions quickly without performing complex compilation or setup during real-time operations.
3Reliability
If integrated multi-domain control is used, then operational risk reduction is achieved, but system complexity and integration difficulty worsen
Solution Approach 1:
The PDDL planning framework acts as an intermediary layer between different drilling domains and the control system. This standardized interface mediates communication between domains, enabling integrated control and comprehensive risk management without requiring direct complex point-to-point integration between all system components.
Solution Approach 2:
The unified PDDL planning system provides universal control functionality across all drilling operations (drilling, completion, workover). This single multi-functional system reduces operational risks comprehensively while avoiding the complexity of maintaining separate specialized control systems for each domain.

AI summary
A method can include, in a runtime environment of compiled multi-domain code for multiple different domains that describe physical operations performed using equipment, responsive to input, issuing a call to a planning domain definition language planner; responsive to the call, receiving a plan that includes at least one action; and dispatching at least one of the at least one action to call for performance of at least a portion of at least one of the physical operations.
