Real-time automated control and characterization of drilling fluid rheology
Problem statementDrilling is one of the most expensive activities in any oil and gas operation. Monitoring drilling and completion fluid and maintaining these at desired levels of viscosity and density is essential for optimum drilling fluid performance, efficient hole cleaning, and Equivalent Circulating Density (ECD) management, as well as preventing...
RAPIDClean: fast, accurate real-time simulations for hole cleaning operations
Problem statementImproper hole cleaning is a major cause of non-productive time (NPT) in drilling. Current hole cleaning practices are mostly based on experience, rules of thumb and simplistic calculations, and do not necessarily work as expected in all scenarios. Available models do not include parameters such as fluid compressibility, pipe rotation...
Automated real-time optimization of formation fluid sampling using artificial intelligence
BackgroundFor capital-intensive exploration and production projects, understanding the chemical and physical properties, phase behavior, compatibility, spatial distribution, and hydraulic connectivity of reservoir fluids is critical for long-term planning and operation. Often, reservoir fluid samples acquired via formation testing represent the only...
Advanced sensors for RT determination of mud density and flow rate in high-pressure conditions
Problem statementLost circulation can have disastrous consequences including blowout (uncontrolled kicks) and loss of life, so close monitoring to quickly assess and control such events is essential. Market estimates indicate that over $2 billion USD is spent annually to combat and mitigate these events. Real-time measurement of mass flow is critical...
A cost-effective downhole strain sensor tool for retrofit or new installation
Problem statement Hydraulic fracturing involves fracturing of bedrock formations by pressurized liquids and is one of the key technologies used for unconventional oil production. Usually strains on the order of 10–5 to 10–6 propagate ahead of the fractures. Monitoring and characterizing the strain on wellbores can be a formidable challenge,...
Simple drill system process for accurate determination of formation properties
Problem statementKnowledge of rock mechanical properties at subsurface conditions is essential to hydrocarbon exploration and production industry. Current methods to obtain this data include seismic amplitude measurements prior to drilling, while-drilling methodologies (LWD and MWD) using drill acoustics and post-drilling methods that use wireline logging...
Injection or production of fluids from a single horizontal or deviated wellbore
A versatile system for oil well injection and productionProblem statementRecovering hydrocarbons from low permeability reservoirs is challenging due to low mobility of fluids in pore spaces. Enhanced Oil Recovery (EOR) efforts, including steam injection and chemical flooding, for such reservoirs depend on fluid injections to recover oil unavailable...
