ABSTRACT: TECHNICAL PROGRESS REPORT
Annual Report: June 2001 - June 2002
Realtimezone- George Scott III
Ongoing Phase 2 work comprises the development and field-testing of a real-time
reservoir stimulation diagnostic system. Phase 3 work commenced in June 2001,
and involved conducting research, development and field-testing of real-time
enhanced dual-fluid stimulation processes. Experimental field-testing to date
includes three well tests. Application of these real-time stimulation processes and
diagnostic technologies has been technically successful with commercial production
from the "marginal" reservoirs in the first two well tests. The third well test proved
downhole-mixing is an efficient process for acid stimulation of a carbonate reservoir
that produced oil and gas with 2200 psi bottomhole reservoir pressure, however,
subsequent shut-in pressure testing indicated the reservoir was characterized by
Realtimezone continues to seek patent protection in foreign markets to the benefit of
both RTZ and NETL. Realtimezone and the NETL have licensed the United States
patented to Halliburton Energy Services (HES). Ongoing Phase 2 and Phase 3 field-
testing continues to confirm applications of both real-time technologies, from well
testing conducted over the last 12-month work period and including well test
scheduled for year-end of 2002.
Technical data transfer to industry is ongoing via Internet tech-transfer, public
presentations and industry publications. Final Phase 3 test work will be focused on
further field-testing the innovational process of blending stimulation fluids
downhole. This system provides a number of advantages in comparison to older
industry fracturing techniques and allows the operator to control reservoir fracture
propagation and concentrations of proppant placed in the reservoir, in real-time.
Another observed advantage is that lower friction pressures result, which results in
lower pump treating pressures and safer reservoir hydraulic fracturing jobs.
Here’s what’s next.
