HORIZONTAL SHALE WELL OPTIMIZATION
Many decisions go into drilling and completing a horizontal shale well, which means that there are also many areas for potential optimization. For example, lateral landing point, completion program, and perforation design play a large part in how a well performs. All are variables that we, as engineers, influence and are areas where we specialize.
Our team's expertise and abilities lie in determining the results of these decisions in terms of the completion and how they affected the overall performance of the well. This knowledge and understanding of the reservoir are crucial for optimization.
Hydraulic Fracture Modeling
BCI uses the Meyer integrated suite of software to design and analyze hydraulic fractures using both 2D and 3D models. MShale, a discrete fracture network (DFN) fracture model, uses client-provided data to describe the reservoir, the well, and the resultant hydraulic fracture conductivity and dimensions for a given completion design. The specific focus of these projects can be one or several of the following:
Lateral landing point sensitivity
Hydraulic fracture design/analysis
Determination of created fracture properties for use in a production simulation model
Cluster Efficiency and Fracture Pressure Analysis
Applied Post-Job Analytics (APJA) is a post-job engineering-based analysis of horizontal well fracture treatment data that communicates meaningful patterns and results about the completion that include …
Perforation and Cluster Efficiency Analysis
2D Fracture Geometry and Contacted Area
Stress Shadowing and Geomechanical Effects
APJA is a rigorous analysis of each well's specific treatment data to determine the fracture design and completion effectiveness. This work is done with 2D fracture propagation models to promote first-order modeling efficiency that encourages application to more wells. Indeed, when applied to a single well, this methodology is informative. Still, with rigorous engineering review and integration of multiple stages and multiple wells, meaningful trends develop, and large-scale value emerges that will support improved design changes.
The process was developed in-house, published over several technical papers, and validated with multiple tracer and fiber optic data sets.
Correct end of job ISIP by considering Storage+Mid-Field Fracture Complexity Effects (SPE #176919) to define true width-opening net pressure for fracture geometry determination.
Define apparent net pressure trend that describes stress shadowing effects (SPE #140514) and how they relate to friction and geomechanical effects.
Calculate created and propped 2D PKN geometry, contacted Reservoir Volume, Mid-Field Fracture Complexity extent, and proppant volume inside fracture.
Calculate open perforations and estimate contributing clusters to determine equivalent cluster spacing with no need for Step-Rate Tests.
Production Simulation & History Matching
MProd, from the Meyer suite of software, is a single-phase analytical production simulator and the tool we use for production simulation and history match production simulation. We use this in conjunction with unconventional Rate Transient Analysis (RTA) workflows to obtain a solid understanding of the reservoir and the resultant completion.
Fracture and Production Optimization
The final step is pulling all of this together in a way that includes all of the relevant data that has been acquired and the modeling work performed to arrive at an optimized design
Over time operators acquire data about their wells and their reservoirs, but the total value of the data has not been recognized. No oilfield data is cheap to obtain, so pulling every ounce of value from it is essential. Our team has the knowledge, tools, and ability to understand each data set's worth and then integrate this data to unlock its full potential.
Our team of on-site supervisors have extensive experience across all major unconventional basins in North America and do far more than ensure proppant gets pumped. Before any job, the client sets key performance indicators (KPIs) and agrees upon them. These KPIs can range from logistics, NPT tracking, and even safety metrics recorded and then compiled into an end of well report for the client.
The BCI team is a preferred trainer for the Meyer Suite of Software and can provide individual or team training on any of these tools.
Additional formal training courses include:

Unconventional completion design and theory
