SOLUTION 63 Nest has been tested on 3 real fields. The result is the following: WELL INTERVENTIONS OIL PRODUCED KTONS OF EXTRA INCREASE OIL PRODUCTION 105 Nest provides a solution for geologists and oil field operating companies. In a few clicks 70% are customized for individual well parameters. or maintain oil production rates. All Nest solutions to do and which wells shall be involved in order to increase of appearance, and, most importantly, it proposes ready solutions: what is required and seconds it finds wells with production losses, defines their amounts, time and reasons ROBOTIZED OILFIELD DEVELOPMENT (BIG DATA)

Nest provides recommendations using rationale logic. Nest 2014 INTELLIGENCE ARTIFICIAL Machine learning Customized % to determine well performance anomalies, calculated impact of each well on other wells for each cell of the field during flooding. Examples of customized approach: even for not too many wells. have enough time for such detailed analysis Reservoir and production engineers do not for each well, based on empirical data (BIG DATA). The software makes assumptions customized replaced with robotization production engineers are Many tasks of reservoir and Nest 2015 Evolution of oilfield development software AUTOMATION, Monitoring (Landmark) DecisionSpace Production Avocet IAM, OFM (all SLB), Avocet Surveillance, solutions: Avocet, Examples of software tailor the approaches to meet the requirements of the exact wells. Robotic customized approach includes using algorithms capable of returning to the software source code when new experience (BIG DATA) is accumulated, and APPROACH WITH A CUSTOMIZED ROBOTIZATION ROBOTIZATION ANALYSIS ANALYSIS TOOLS SOLUTION
Nest answers the question “ What to do? ”, but it doesn't answer the question “ How to do it ?”. That's why Nest in no way influences well operations. Here it is required to address CHECK AND VALIDATION OF MEASUREMENTS REGISTRATION OF ANOMALIES RELEVANT MEASURES the question “How to do it?” RECOMMENDATIONS Monthly work to select well intervention techniques (more relevant to reservoir engineers) Nest doesn't solve this problem Nest solves this problem A reply to the question “What to do for a well?” MEASUREMENTS GENERATION OF Nest is a support tool for reservoir and production engineers. It saves a significant amount of time both for real-time solutions A reply to the in case of unexpected production anomalies, and for long-term solutions. Production Lifecycle Management DETERMINATION OF REASONS LEADING TO ANOMALIES GENERATION OF RECOMMENDATIONS question “What PRODUCTION to do for a well?” Work of oilfield and production engineers Daily work of production and reservoir engineers SEARCH FOR NEW POSSIBILITIES OF HOW TO INCREASE SOLUTION
