SPECIFICS OF VISCOUS OIL PRODUCTION USING A DRAIN-HOLE WELL

A Successful Experience in Optimization of a Production Well in a Southern Iranian Oil Field

A Novel Integrated Approach to Oil Production Optimization and Limiting the Water Cut Using Intelligent Well Concept: Using Case Studies

Intelligent well technology has provided facility for real time production control through use of subsurface instrumentation. Early detection of water production allows for a prompt remedial action. Effective water control requires the appropriate performance of individual devices in wells on maintaining the equilibrium between water and oil production over the entire field life. However, there...

Optimal Well Placement Improves Heavy Oil Production

Compared to vertical or lowinclination wells, horizontal wells can deliver higher production rates, higher recovery factors, and more efficient use of steam in thermally enhanced recovery projects for heavy oil. However, the shallow, thin, and friable sand reservoirs in Columbia’s Girasol field present several challenges to the accurate placement of horizontal wells. Schlumberger was contracted...

Macular hole surgery using silicone oil tamponade.

BACKGROUND/AIMS Most surgeons performing macular hole surgery using long acting gas recommend strict postoperative face down posturing for 10-15 days. Patients with chronic systemic illness such as arthritis may be unable to carry out this postoperative regime. Thus there is a need for alternative techniques that would eliminate such a regime. The authors review a series of patients who underwe...

Statins for the treatment of asthma: a discovery well, dry hole or just snake oil.

and the NIH funded COPDGene Project. It is not essential to solve the dilemma of whether the term COPD expresses correctly the protean clinical presentations of the same disease or that it combines different clinical entities, but it is necessary to realise that there are needs and research opportunities in an area that is largely unknown. The words ''expira-tory airflow limitation'' expresses ...
