04/25 AM UPDATE - REGISTERED ATTENDEES - LUNCHEON STILL ON

Unconventional development of oil and gas shale and tight reservoirs has globally become very active in recent years. Current resource development focuses on primary depletion utilizing the initial reservoir energy to drive oil through complex fracture networks created through hydraulically fractured completions. Often, optimized hydraulic fracture designs deliver high initial production rates which rapidly decline until stabilizing at a relatively low rate and maintaining that rate for many years. Overcoming these trends to improve recovery is a major challenge.

This presentation describes the workflow and results associated with designing and field-testing two EOR (enhanced oil recovery) technologies in shale and tight reservoirs.

The first one is the application of using surfactants as a stimulation fluid additive in existing horizontal wells.

The second is a hydrocarbon gas EOR pilot under a huff and puff scheme. Both pilots were deployed in Permian Chevron unconventional asset.

Emphasis is placed on having a robust field test program that includes comprehensive surveillance and execution planning.

Various analysis techniques, including reservoir modeling and analytical methods such as rate transient analysis (RTA), decline curve analysis (DCA) and tracer response, are combined to provide an integrated interpretation of test results. The pilot results confirmed the major recovery mechanisms with quantifiable EOR responses.
