Well Delivery Difficult Index

Estimate precise project contingencies.,A quick and efficient alternate for project., Advanced and accurate drilling difficulty.

Why WDDI?

Drilling is complex and prone to unpredictable risks,unlike other industries with more predictable outcomes.

WDDI is a model that provides a reliable well contingency (WC) based on Well complexity, ensuring realistic project economics,preventing cost overruns , and avoiding excess capital raising.

Why You Need This?

Drilling consumes 45-60% of field development costs, making accurate contingency planning critical.

Traditional contingency methods (e.g., AFE, Monte Carlo, P90) are often inadequate, leading to unsustainable project economics or compromises in deliverables.

WDDI addresses these by considering 45 key factors influencing,

Drilling Efficiency

Risk

Time & Cost

How does WDDI work?

By exhaustive studies, research and discussions with project managers we have identified 45 factors that affect project delivery. These 45 factors have been categorized into three groups namely Leading, Lagging and Fixed.

Leading factors reduce the complexity of the project while Lagging factors increase the complexity. The Fixed factors are those that are uncontrollable
By using Reductio-ad-absurdum WDDI works in five stages of logical sequences to minimise subjective estimates and ensuring reliability in inputs

Factors that Affect the Complexity of a Well

Contingency applied using the general principles may make the budget, project and well economics, and funding requirements may appear to be robust but in reality, they may not sustain as they are not designed for specific well situations.

How is the Well Contingency applied to the Well?

Step 1

Estimate the Most Likely Outcome
The most likely risk,time, and cost of a well are estimated using the preferred well engineering approach- based on data,design,and technical analysis.

Step 2

Add Contingency Buffer
A “Contingency Up To” value is added to the most likely estimates to account for potential uncertainties and operational challenges.

Step 3

Analyze and Optimize Contingency
If needed, the contingency is further analyzed to identify its root causes and develop mitigation strategies to reduce its impact.
