Welcome to the inaugural issue of Petroleum Technology Digest,
a joint effort by World Oil and the Petroleum Technology Transfer Council (PTTC) to provide
independent producers with field-proven solutions to their technical problems. In this publication, the
editors and PTTC staff present several recent case studies of exploration, drilling and production
techniques that have been tested successfully in oil and gas fields within the U.S.
These case studies have been solicited and developed by the PTTC. No
specific application of products or services is endorsed by PTTC. Reasonable steps are taken to ensure the
reliability of sources for information that PTTC disseminates; individuals and institutions are solely
responsible for the consequences of its use.
The not-for-profit Petroleum Technology Transfer Council was formed by the
U.S. oil and natural gas industry in 1994 to accelerate the dissemination of technology to independent
exploration and producing companies, and to communicate industrys needs to the R&D community.
PTTC is funded primarily by the U.S. Department of Energys Office of Fossil Energy, through the
National Petroleum Technology Office and Federal Energy Technology Center, with additional funding from
universities, state geological surveys, several state governments and industry donations. |

Vertical and horizontal redrills tap bypassed
reserves Production was increased by 850 bopd in a section of the offshore California
Carpinteria field held by Pacific Offshore Operators Inc. Zones that had not been adequately drained by
existing wellbores were accessed through a vertical-horizontal redrill program. |

Our Energy Links section has
even more website links divided into convenient categories: Government Agencies, Associations,
Operators, and Vendors/Services. |

Waterflood strategy evolves from improved 3-D
flow unit characterization A high-resolution, 3-D data set, combined with 3-D visualization
tools, led Yates Petroleum to a new waterflooding strategy design an individual waterflood for each
identified major flow unit. |
|
|
Polymer gels improve waterflood sweep
efficiency and oil recovery Polymer gel treatments in injection wells correct water
channeling problems, recovering 15,000 to 25,000 bbl of incremental oil to date. |
|
|
Waterflood in Kansas field should boost
recovery by five million bbl Engineered waterflooding based on integrated reservoir
characterization and modeling work has proven to be profitable in Stewart (Morrow) field in western
Kansas. |
|
|
CT-deployed dewatering system installs quickly
in gas wells A new coiled-tubing-deployed electric submersible pump system addresses liquid
loading in shallow gas wells and is up to 50% faster to install than conventional pumping systems. |
|
|
Using alkaline-surfactant-polymer floods as an
alternative to waterfloods An alkaline-surfactant-polymer (ASP) flood in Cambridge
Minnelusa field at the end of primary production increased ultimate oil recovery to 60.9% of original
oil-in-place from the swept area. |
|
|
New additive provides inexpensive solution to
well and facility cleanup Field performance tests have confirmed that a process to render
most hydrocarbons non-hazardous can provide a fast, safe and economical way to remediate "typical"
spills and leaks. |
|
|
How to reduce electrical power costs without
sacrificing production rate By installing timers and pumping during off-peak hours, Equinox
Oil reduced electrical power consumption in Illinois South Albion field by 25%. |
|
|
Microbial process cuts cost of injection water
treatment in half Overall water treating costs in a portion of Wilmington Oil field in
California were reduced by 50%, without sacrificing protection. |
