Areas of Specialization

Stimulation Design, Analysis, Supervision & Quality Control

Pre-Stimulation Evaluation
Ely and Associates' engineers perform a detailed formation evaluation prior to the design of a stimulation treatment. Well test data, logs, core data, etc. are all evaluated and considered in design of an optimized stimulation treatment. Ely and Associates' engineers also make completion recommendations for optimizing stimulation. Such completion recommendations include casing and cementing programs, perforation placement and breakdown/ bailout procedures.

Stimulation Design
Utilizing information evaluated in the pre-stimulation formation evaluation, Ely and Associates uses sophisticated fracture design software to design a stimulation treatment.
Ely and Associates personnel also stay updated on the latest technology in fluid and proppant selection. This helps to assure the client that he receives the best available fluid, additives, and proppant for his application.

Stimulation Supervision and Quality Control
Ely and Associates' personnel have over 100 years of combined experience in field supervision and quality control of stimulation treatments. Detailed supervision, which includes quality control of fracturing fluids and additives, is essential for the success of all hydraulic fracture treatments. Basic quality control procedures, such as monitoring fluid viscosity and conducting pre- and post-treatment inventories, are performed on every treatment Ely and Associates supervises.
Additionally, Ely and Associates can provide intense quality control, which includes the prejob analysis of fluid viscosity on site at in-situ conditions, to determine gel stability and proper breaker loadings.
After the frac treatment, Ely's engineers provide recommendations for flow back of the well to maximize frac fluid cleanup and minimize damage to the fracture.

Post Stimulation Evaluation
Ely and Associates' personnel can also design, conduct and analyze post-stimulation pressure transient tests along with the analysis of production history to evaluate the effectiveness of the stimulation treatment.

Coalbed Methane Projects
Ely and Associates have been involved in numerous coalbed methane projects in Alabama, New Mexico, Wyoming, Colorado, Utah, Kansas, as well as Europe and Australia. New fracturing techniques and fluid systems have been developed by our firm for these areas. In most cases, due to relatively low bottom hole temperatures and pressures of coalbed methane deposits, quality control on these wells is critical to their success.

"Frac Pack" Stimulation Treatments
Ely and Associates' personnel have been been in the forefront of high permeability fracturing in the Gulf of Mexico, the North Slope and throughout the world. On-site diagnostics and optimization of tip screenout treatments for near wellbore damage removal as well as quality control of gravel pack operations are services supplied since the inception of the company.

On-Site Quality Control of Critical Cementing Treatments
Ely and Associates' personnel have a tremendous amound of experience in design and optimization of critical cement jobs for onshore and offshore operations

Short Courses

Hydraulic Fracture Treatment Design and Quality Control
This course offers insight into the theory and practice of hydraulic fracture treatment design. Topics covered include pre-fracture formation evaluation, well completion for stimulation, fracture design models, and selection of fluids, fluid additives, and proppants. Onsite fracture monitoring and quality control are also discussed in detail.

Hydraulic Fracture Treatment Evaluation
This course describes analytical techniques which can be used in the evaluation of hydraulic fracture treatments. Topics covered include post-fi.acture pressure transient test analysis, predicting performance and estimating ultimate recovery from fractured wells, fracture treatment optimization and the effect ol non-ideal conditions susuch as fracture closure, variable fracture conductivity, fracture damage, and non-Darcy flow on post-fracture well performance. Because of its importance to post-fracture analysis, pre-fracture formation evaluation and test analysis are also discussed.
This course is designed for reservoir and production engineering responsible for evaluating the results of hydraulic fracture treatments and predicting post-fracture well performance. It is our ideal follow-up to the Hydraulic Fracture Treatment Design and QualityControl short course.
