Describe the scope of work in detail. Please include a summary of key deliverables.
The challenge of the project was to determine the lithological type of the soil in the process of drilling an oil well in real-time 30 meters ahead of a sensor and, in consequence, make the process of drilling a well and its usage less unprofitable and more efficient. To solve the main problem, it was required to build a tool for calculating interpretations automatically.
To achieve this result, we used XGBoost and the method of predictive analytics that allowed us to predict what would happen when drilling an oil well 20 meters ahead of the sensor unit at the end of the plugged bit. A large part of the case was devoted to the data preparation for training to predict the lithological difference effectively.
In the course of problem-solving, it was established that for effective prediction it is necessary to use underground maps, which are known as interpretations so we made this as well. The solution has been successfully deployed and allowed the company to save money by using it as a part of an interface for well-drilling machines operators.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
Through this project we built a mathematical model that forecasts what formation will occur 50 meters ahead of the sensors, based on MWE and MWD.
Value for Drilling Engineers is to reduce the risk of missing the target formation.
Value for an oil-producing company is to reduce costs of drilling well due to inherent risk that can cost $100 000 - $2 000 000
Describe their project management. Did they deliver items on time? How did they respond to your needs?
We tracked the number of working hours on Upwork, we also regularly received reports on completed tasks, and we had access to Trello, where we could track the progress of the work. In addition, we had calls once or twice a week to clarify all issues.
What was your primary form of communication with Crazy Pumpkin?

What did you find most impressive or unique about this company?
This team showed a high level of professionalism in solving our complex task, they approached the work on the project very responsibly and carefully. And we were completely satisfied with the result of our cooperation.

We were satisfied with the cooperation and did not encounter any difficulties. We can definitely advise Crázy Pumpkin as a reliable partner who can help in solving even very complex and non-trivial tasks.

BACKGROUND
Please describe your company and your position there.
I'm an executive at OmegaLab.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Crazy Pumpkin, and what were your goals?
We had a large-scale project for a client in the medical sector and lots of things weren't working properly, the task was very complex - fixing existing bugs and also developing new features for the patient portal.
SOLUTION
How did you select this vendor and what were the deciding factors?
We found them through referral
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
We started working together over a year ago on a large medtech project when we needed more resources, we started with a trial period and then integrated their tech lead into our processes to work on the bug fixing first, they helped us plan the initial bug fixing assessments and fixing tasks and they helped to outline milestones for each iteration before testing.
We then requested for 3 more of their developers to join our team - one for bug-fixing issues and the other senior developer for new feature development. The tech lead that we hired first was the one who was helping with the management and orchestrating of the whole project that's why we then asked them for more people to join another project as we needed some help with technical management there.
How many people from the vendor's team worked with you, and what were their positions?
1 CTO/tech lead 1 Senior full stack developer 1 Python developer 2 front end Angular developers 1 AI/Machine learning engineer
RESULTS & FEEDBACK
Can you share any measurable outcomes of the project or general feedback about the deliverables?
The guys at Crazy Pumpkin helped us with the bug fixing (this process took less time than we initially planned because the team was very organized and fast, it took us 30% less time for this stage than we planned) and also with the development of the new features and we've also invited them to join another project in fintech that we're still working on together.
They are all very knowledgeable with great expertise, mathematical academic backgrounds, and great work ethics which helps a lot when working with such complex projects and developing long-term business relationships.
Describe their project management style, including communication tools and timeliness.
We used Slack and telegram for communication with Google Meet planning calls, the team was always very efficient with communications and always provided updates on time, and always communicated any issues straight to us so we could solve them quickly. For project management we used Jira and Trello and for time tracking we used Toggl.
What did you find most impressive or unique about this company?
We had almost 24/7 access to the team, it felt like they are actually part of the company rather than a distant outsourcing agency, they are actually there when we need them and ready to jump on a call with a 10min notice. They also are very knowledgeable with mathematical and engineering academic backgrounds (quite a few senior developers have PhD levels) which is quite impressive.
Are there any areas for improvement or something they could have done differently?
Not sure, we're very happy with this partnership as the code quality is amazing and the communication is also great...
