Low Frequency (3-D) Seismic Identifies
Hydrocarbons | Low
Frequency (LF) seismic anomalies associated with hydrocarbon
reservoirs have been observed by various industry and
academic groups. Spectraseis has invested heavily in both
research and in computer software to develop workflows for
reducing both transient and stationary noise, calling on experience
from over 30 LF surveys around the world. Data are
acquired using well known, standard equipment. Broadband seismometers nominally record data for 24 hours to
capture a full diurnal cycle. Noise is then separated from
potential hydrocarbon reservoir-related signals utilizing
methods in the time, frequency and spatial domains. After
analyzing the data for possible near surface effects,
statistical attributes are calculated that can be related to
hydrocarbon potential and ultimately to reservoir
parameters. An article in
Hart's E&P March issue discusses
potential LF application in unconventional reservoirs.

Good High-Level Summary of Woodford
Shale Development | An article
in the February issue of
World Oil
("An Unconventional Play with Conventional E&P Constraints,"
by Pramod Kulkarni, Editor) provides a good overall summary
of the Woodford play (geological context, operator activity
and technology challenges). Information is provided about
rotary steerables, advanced LWD and production logging,
high-volume fracing and ultra-lightweight proppants.
Still time to register for the "2011 Woodford Shale Summit," March 29-20, Norman,
Oklahoma --- offered by the University of Oklahoma
and the Interstate Oil and Gas Compact Commission. A
technical session includes presentations titled "Woodford
Production History and Future Analysis" and "Horizontal
Drilling/HF State of the Art Technologies."

Sharewell's EM-MWD Operates Efficiently at Greater Depths
|
Standard mud-pulse MWD technology can't operate efficiently
in deep wells, with lost circulation, no fluid returns or
high lost-circulation material concentrations. Sharewell's
EM (electromagnetic) MWD system however transmits real-time
data via EM signals through the formation instead of using
fluid pressure pulses through the drill pipe. The system
enhances the receiver's ability to extract very weak signals
from large amounts of noise, enabling it to recover
information from EM tools deployed at greater depths or in
geological formations not conducive to EM transmissions.

Petroleum Technology Alliance's (PTAC)
Shallow Gas De-watering Pump Consortium
|
The purpose of this PTAC Consortium is to facilitate the
demonstration of technical performance under simulated and
actual field conditions in order to assist in the
commercialization of new low-cost reliable pumps for shallow
gas wells. PTAC sought proposals from innovators (proposals
were due March 14, 2011). PTAC will use a stage-gated
process, starting with an in-house review based on the
candidates information and testing data. Successful
candidate technologies will advance to bench testing at C-FER
(Centre for Frontier Engineering Research). If bench testing
is successful, the candidate technologies will advance to
field demonstration. Industry partners (Cenovus Energy,
Inc., Encana Corporation, Enerplus Corporation) each
provided direct funding, their expertise and will pick up
costs in the field where testing will be performed.
