Conversion of oil and gas wells to geothermal reinjection
Number of old, disused and abandoned oil wells around the globe is counted in millions. If just a small fraction could be converted for geothermal utilization, it could significantly reduce costs and environmental impact compared to making new wells from scratch. The focus of this project is …

Stuck pipe prediction in deviated wellbores: a numerical and statistical analysis.
… are based on unhindered, free settling in the wellbore and do not adequately account for the effect of vortices created as the drill string rotates about its axis. This thesis addresses both shortcomings, and presents improved cutting transport models that consider hindered centrifugal settling …

Applying Extended Reach Drilling to Optimize the Net Present Value of the Duvernay Field
Lateral length is a key well design parameter that impacts field planning, operations, hydrocarbon recovery, reserves booking and economics. Unconventional assets in North America are looking at long laterals as a potential to reduce Unit Development Costs (UDC) and maximize Net Present Value …

The design of a coiled tubing cutter for use in subsea oil drilling applications
… disconnect of an offshore system from a subsea wellhead during the testing of the well. Design requirements for the device were established by the requirements of the SenTree tool. Additional force requirements for the prototype were established through theoretical models and experimental tests. …

Efficient Modeling, Optimization, and LLM-Assisted Decision Support for Geothermal Well Arrays
Geothermal well arrays, which organize multiple geothermal wells into carefully planned geometric configurations, provide an opportunity to enhance energy production capacity and increase fault tolerance of geothermal systems. Closed-loop geothermal systems (CLGS), a type of geothermal well design, …

Artificial Recharge of Groundwater with Recycled Municipal Wastewater in the Pajaro Valley
… clogging can be significant in direct injection wells, but well design and maintenance can effectively address clogging. Surface spreading basins require less engineering and have lower operating costs than direct injection, and they are able to accommodate fluctuating flows of water, unlike …
