A Calculation Model for Steam Property Variation Along Wellbore Trajectory in SAGD Process
Steam-Assisted Gravity Drainage is an effective approach for recovering heavy oil and bitumen and its essence idea is to introduce steam heat into cold reservoir and reduce oil viscosity. In a typical SAGD process, two horizontal wells were drilled inside the target formation, one is put on the top …

Effectiveness of microseismic monitoring for optimizing hydraulic fracturing in California
… California provides a unique case study because steam injection, a type of hydraulic fracturing, has been used there for more than 60 years. Seven companies, varying in size and strategy, use steam injection in California. Some of these companies use microseismic monitoring technologies to …

Effects of high levels of steam addition on NOx̳ reduction in laminar opposed flow diffusion flames
… off" trend in NOx emissions with high amounts of steam addition has been observed in industrial gas turbine diffusion flame combustors. Experiments were performed to try to reproduce this trend in a laminar, opposed flow diffusion flame burner. Experiments were performed with Cli4, C2H4, CO, COIH2 …

On Steam Based Recovery Process Design
Steam-based thermal recovery process is the most commonly used recovery process for bitumen production from oil sands reservoirs. The most used thermal methods are Steam Flooding (SF), Cyclic Steam Stimulation (CSS), and Steam Assisted Gravity Drainage (SAGD). The choice of method depends on the …

Evaluation of Propane-Butane Mixtures as Solvent in ES-SAGD
SAGD (Steam Assisted Gravity Drainage) is a thermal recovery process for production of nearly immobile bitumen from the deeper oil-sand formation. In this method, two parallel horizontal wells are drilled near the reservoir bottom, one about 5 m higher than the other. Steam injected through the …

Single Well Completion and Management Strategies for Enhanced Recovery of Tight Oil Using Miscible Gas Injection
… well to well displacement using water and gas as injection fluid failed in tight oil largely due to short-circuits along fractures connecting adjacent injection and production wells. As an alternative, operators have tried alternating miscible gas injection with production in a single well …

Since there is no shallower production or steam injection for this particular field, the repeat surveys should have the same overburden, tuning, multiple-related and converted wave contamination. It appears reasonable to assume that any changes in amplitude between the repeat surveys would …
