Aggressively Passive:
Microseismic Opportunities Over an Oilfield’s Life

Presented by Peter M. Duncan
MicroSeismic, Inc., Houston, Texas

Passive seismic, especially microseismic monitoring, is to conventional seismic as a stethoscope is to a sonograph. It is continuous 4D. It is accomplished by listening carefully to the sounds emanating from the earth and then diagnosing what is happening down there. Passive seismic techniques not only can create an image of the reservoir and its plumbing, but also shed light on how the fluid is flowing through the pipes.

Grasping the completeness of the passive science, one can see that it provides the opportunity to contribute over the lifetime of an oilfield from discovery to abandonment. Passive seismic can accomplish reconnaissance 3D exploration at an attractive cost and lead to new discoveries. Microseismic monitoring of a hydrofrac can and does provide valuable information on completion and development strategy. Gas or fluid injection operations for primary or secondary recovery are prime candidates for passive monitoring to prove regulatory compliance, validate reservoir conformance, and estimate recovery efficiency.

This lecture will present a view on the history and development of passive seismic techniques, a discussion of state of the art through case histories, and a vision on where this technology will play a role in the smart oil field of the future.

Rock Physics modeling of Unconsolidated Sands: Accounting for Non-Uniform Contacts and
Heterogeneous Stress Fields in the Effective Media Approximation with applications to
Hydrocarbon Exploration

We show that by treating the contact stiffness as a variable, one can extend the effective
medium approximation used to obtain elastic stiffness of a random pack of spherical grains.
More specifically, we suggest calibrating the effective media approximation based on
contact mechanics by incorporating non-uniform contact models.

The simple extension of the theory provides a better fit to many laboratory and field
experiments and can provide insight to the micromechanical bonds associated with
unconsolidated sediments.

This approach is motivated by repeated observations of shear-wave measurements in
unconsolidated sands where observed shear-wave velocities are lower than predicted
by the Hertz-Mindlin contact theory.

We present in detail the calibration process for well-log data from a North Sea well
penetrating a shallow gas discovery and a deepwater well in the Gulf of Mexico.
Finally, we demonstrate the benefit of using this model
for AVA analysis of shallow sand targets in exploration and reservoir studies

Talk #1 "Some Applications of Wavelet Transform in Seismic Data Processing"

Ground-roll, swell noise, guided waves, and random noise are just some of most persistent types of noise in land, marine and OBC data. These types of noise can be hard to remove with traditional Fourier-based methods without damage to the signal. Wavelet Transforms present a relatively new set of tools to aid seismic processing. These tools have been successfully applied for compressing and de-noising purposes. In this talk I will give a brief theoretical background for Wavelet Transforms and provide details about some of the wavelet-transform-based filters and algorithms used in the research community. I will show results of both 1D and 2D Stationary Wavelet Transform (SWT) - based filters for groundroll and coherent noise removal in prestack data. I will also show 2D SWT filters for acquisition footprints and random noise suppression in poststack data. More recent applications of SWT would include F-X deconvolution and resolution enhancement in wavelet transform domain.

Talk #2 "High - Order Seislet Transform"

The seislet transform is a wavelet-like transform that analyzes seismic data by following variable slopes of seismic events across different scales. In the case of multiple components, the transform turns into a frame (an invertible overcomplete representation) and becomes suitable for analyzing data with multiple frequencies (in 1-D) or multiple plane-wave slopes (in 2-D and 3-D). We extend this approach to a higher order, using t he Cohen-Daubechies-Feauveau 9/7 biorthogonal wavelet transform (the basis for the JPEG2000 compression scheme) as a template. Using synthetic and field-data examples, we demonstrate that the new transform can provide a better compression rate for seismic events than the Fourier transform, discrete wavelet transform, or the low-order seislet transform. Therefore, the high-order seislet transform can be more suitable for data processing tasks such as data regularization and noise attenuation.

4D Seismic in the Deepwater – Challenges and Rewards

David H. Johnston

ExxonMobil Exploration Company

Time-lapse or 4D seismic data has proven value in reservoir management, increasing reserves and recovery by locating bypassed and undrained hydrocarbons and optimizing infill well locations and flood patterns. 4D seismic can also decrease operating costs by reducing uncertainty in the reservoir geologic model and flow simulation, optimizing completions, and minimizing the number of dry holes. 4D is simply the use of multiple seismic surveys shot over a producing field. Changes in the seismic response typically occur because of production-induced changes in saturation and pressure. Successful 4D projects have been carried out in a wide range of geographical areas, geological settings, and depletion scenarios.

To maximize the value of a 4D seismic project, planning for 4D is a critical part of an overall field lifecycle strategy. In exploration, assets can be screened for potential 4D application. Early in development planning, 4D seismic models based on reservoir flow simulations and geologic models are used to estimate the magnitude and interpretability of the 4D response, evaluate optimal survey repeat times, and assess potential business impact. Once the field is under production, effective 4D project execution requires collaboration among asset team geoscientists, engineers, and field operations with geophysical acquisition and processing specialists.

ExxonMobil’s experience in West Africa and the Gulf of Mexico demonstrates that the deepwater production environment presents unique opportunities and challenges for 4D projects. Issues range from the impact of surface facilities on data quality to contending with ongoing field operations. In addition, aggressive drilling schedules dictate a rapid turnaround of 4D data. But these fields have high drilling and well intervention costs and 4D seismic may be the only available field-wide reservoir surveillance tool. This presentation shows how ExxonMobil uses 4D seismic technology in deepwater reservoir management and discusses some of the challenges faced in its applicationTEST
