BP is a multinational oil and gas company headquartered in Houston, Texas. It is one of the world's seven oil and gas "supermajors", whose performance in 2012 made it the world's sixth-largest.

Achievements/Tasks

Team leader for the Information and Data Management Team in the Global Wells Organisation (GWO) in upstream BP Africa, Brazil, Australia, and Nova Scotia.

Business change lead, and coordinated the implementation of business solutions, such as SAP, Well Integrity Management Systems, Work Management tools, Data Management systems, and many more.

Provided basic information and data support and services relating to unstructured data working across all business teams within the Global Wells Organisation

Developed and maintained processes and supporting tools for information and data control.

Interfaced information and data control resources with partners, vendors, regulatory agencies, and other external bodies, keeping distribution contacts current.

Extracted data from well-logging systems (e.g. OpenWells, CasingWear, StressCheck, Well Cost, and Campos, among others) to build machine learning algorithms to solve various problems.

Built an Ensemble Learning Algorithm to predict whether or not there will be deviation at any given well depth in a drilling operation.

Used an MLP Neural Network to predict Torque and Drag in order to minimize/avoid well casing, and formation damage.

Processed huge datasets (over billion data points and 2 TB in size) for data association pairing and provided insights into meaningful data association and trends.

Used Python 3.0 (NumPy, SciPy, Pandas, SciKit-Learn, Seaborn, NLTK) and Spark 2.0 (PySpark, MLlib) to develop variety of models and algorithms for analytic purposes.

Used NLP techniques to do sentiment analysis using data from social media API
