WASHOUTCREEK 3C 3D

Arcis Seismic Solutions is pleased to announce Washout Creek 3C 3D survey located in

Township 46, Ranges 6 to 7 W5 and is currently available for immediate subscription.

This survey is designed to evaluate multiple zones from the Cretaceous to Devonian,

including producing formations such as Cardium, Belly River, Glauconitic, Rock Creek and

Duvernay.

In addition to this survey’s optimal acquisition parameters, Arcis provides proprietary tools

that will enhance imaging and azimuthal fold distribution for even greater assistance with the

placement of horizontal wells upon both deep and shallow targets.

Comprehensive Multicomponent Toolkit

Arcis Seismic Solutions’ multicomponent processing technology consists of a comprehensive toolkit of algorithms and workflows up to anisotropic PS

PSTM. These are used in conjunction with many years of experience in processing challenging land 3C (PP & PS), and 9C (PP, PS & SS), and ocean

bottom 4C (PZ & PS) datasets.

While it’s obviously challenging to adequately characterize the very thin Cardium formation

with surface seismic, we have had favourable feedback related to our work in the Bakken,

which might bear reasonable analogy to the Cardium play. In that case, the Bakken itself was

deemed to be too thin to admit fracture characterization, but by analyzing the anisotropy in

the thicker overburden, we were able to make certain important inferences about the Bakken

proper. With our high-effort, 3D/3C acquisition parameters, we are seeking favourable spatial

sampling for the wide azimuth coverage which is appropriate for applying various azimuthally

dependent fracture characterization techniques.

In particular, Shear-wave splitting fracture estimates from the 3C processing, as well as the

AVAZ/VVAZ/Curvature fracture estimates from the PP Processing, could give insight into the

fracture regime of the overburden. Further information about the overburden may be gleaned

from the analysis of the VP/VS ratio that comes out of the 3C processing (high values of VP/

VS tend to indicate more local anomalies where the lithology is less competent). We could

conceivably validate these various attributes against production data from nearby wells.

We intend to undertake, as a value added product, the additional processing of the 3C data/

AVAZ/VVAZ/curvature and we will seek production statistics to correlate.
