This my first column as Executive Editor of the Reservoir Engineering (RE)
part of SPE Res Eval & Eng. I would like to start by thanking Anil
Ambastha for his efforts as Executive Editor during the last 3 years. As RE
Executive Editor of SPE Res Eval & Eng, Anil managed the review of
more than 300 papers and reduced the average turnover time to 60 days per RE
paper. I am happy that Anil has decided to continue as an Associate Editor for
This brings me to the peer-review process, which is an essential part of
SPE’s mission to disseminate knowledge. The peer-review process aims to
guarantee the quality of the published papers as well as a timely review of all
submitted papers to expedite the sharing of new ideas and knowledge. Currently,
SPE Res Eval & Eng has approximately 30 Associate Editors and a
large pool of Technical Editors who do the actual reviewing. However, to
maintain the quality and timely delivery of reviews, we need more qualified
people who want to commit to conduct paper reviews. If you are interested,
please look at http://www.spe.org/authors/docs/pr_process.pdf.
This issue brings you 10 papers that reflect areas of current activity in
the industry. Two papers on formation evaluation discuss new, better, and
faster ways to collect data during drilling and also during injection
processes. There are three papers that provide improved understanding of
tight-gas-development schemes and resource quantification. Three other papers
cover aspects of different enhanced-oil-recovery processes.
Characterization of Sampling-While-Drilling Operations presents the
results of a study that compares the quality of sampling-while-drilling
operations with conventional wireline-formation-sampling techniques.
High-Resolution Reservoir Monitoring Using Crosswell Seismic provides a
brief description of the measurement theory and its capabilities and
illustrates the application of the technique with two case histories.
Impacts of the Number of Perforation Clusters and Cluster Spacing on
Production Performance of Horizontal Shale-Gas Wells presents the results
of a simulation study that aims to quantify the geomechanical effects of
fracture spacing in horizontal wells used in tight gas developments on the
production performance of such wells. Probabilistic Production Forecasting
for Unconventional Reservoirs With Stretched Exponential Production Decline
Model presents a probabilistic performance forecasting method for
stimulated wells in unconventional gas reservoirs with and without production
histories. A New Analytical Method for Analyzing Linear Flow in Tight/Shale
Gas Reservoirs: Constant-Rate Boundary Condition presents an analytical
method for analyzing pressure responses in tight gas reservoirs completed with
wells with multiple fractures.
Enhanced Oil Recovery
The Role of Diffusion for Nonequilibrium Gas Injection Into a Fractured
Reservoir contains a study that illustrates how the oil production from a
fractured dolomite field that has been produced for 50 years could benefit from
using the same reservoir for gas storage. The increase in oil production is
governed by the diffusion of gas components into the oil. Validation of
Toe-to-Heel Air-Injection Bitumen Recovery Using 3D Combustion Cell Results
presents simulation results that demonstrate that laboratory results of
air-injection experiments with an unconventional injector/producer geometry can
be reproduced numerically. Thermally Active Polymer To Improve Sweep
Efficiency of Waterfloods: Simulation and Pilot Design Approaches presents
a workflow for the evaluation of the technical feasibility of in-depth
conformance treatments, which may improve the sweep efficiency of
Carbon Capture and Sequestration
Storage of CO2 as Hydrate in Depleted Gas Reservoirs presents results
of a simulation study that evaluates the technical feasibility of
CO2 storage as hydrate in depleted methane gas reservoirs.
Gas Lift Optimization Using Proxy Functions in Reservoir Simulation
the paper describes an efficient gas lift optimization scheme that combines
single well type analysis with surface network analysis depending on the
interaction between the wells.
The above papers were all reviewed and ultimately approved in the
peer-review process. However, the conclusions presented in these papers are not
cast in stone. As sharing of knowledge and experiences is essential, SPE
welcomes further "discussion" of any paper published in any SPE journal.
Therefore, please feel free to submit a discussion of a paper to SPE. I look
forward to receiving such discussion letters.
