Well Stimulation and Sand Control

Diagnose production problems related to formation damage and recommend appropriate solutions. Upon completion of this module, the participant should be able to: diagnose various types of formation damage and identify stimulation candidates, design a matrix acid stimulation treatment based on specific well conditions and reservoir characteristics, specify the materials, equipment and pumping schedule for a hydraulic fracturing procedure, and apply traditional and modern sand control methods to optimize well productivity.

Optimizing Matrix Stimulation Treatments for Carbonate Completions

​Matrix stimulation treatments in carbonates are generally considered to be low risk. Production increases from these treatments are routine and the "success" of these treatments are perceived to be high. However, many treatments realize only a small fraction of the true well potential. If a more rigorous evaluation criterion is used, many treatments would not be considered successful.

Sponsored Webinar: Extending the Life of Your Maturing Assets— Acid Stimulation and Water Conformance

In most conventional reservoirs, less than 50% of recoverable hydrocarbons are delivered in the initial development phase. As capex budgets tighten, operators continue to explore means of maximizing production from their existing well assets. Current production and projected opex vs. capex trends show an increasing demand for maximizing production from existing and maturing wells. These macro drivers have steered development efforts in key segments, including acid stimulation and water and gas conformance. Join our Schlumberger experts as they discuss how you can extend the life of your maturing assets with a focus on stimulation and conformance. A cursory look into the challenges and design workflows, coupled with cost-efficient, sustainable, and low-risk innovative solutions will be reviewed in this very insightful seminar. Content for this webinar is provided by Schlumberger. By registering, your contact information will be shared with the sponsor.

The Role of Inflow-Control Devices in Optimizing Horizontal Well Performance

Downhole sensing technology today provide engineers continuous measurements for flow condition diagnosis. The measurements include temperature, pressure, acoustic, and strain, with distributed temperature sensors (DTS) and distributed acoustic sensors (DAS) being more commonly used compared with other measurements. Since the optical fiber technology introduced to the industry, it has advanced dramatically. Many field applications have been proven effective and beneficial. From downhole flow condition characterization, we can diagnose flow problems, monitor, control, and optimize producing and injecting well performance, monitor well stimulation, both matrix acidizing and hydraulic fracturing, and optimize treatment designs. There are rich field application examples to show the potential of the technology. One of the keys of applying downhole sensing technology is to develop models and methodologies to interpret the senor measurements. This is challenging, because from data collection and processing, to model development, to invert the measured parameters to flow profiles, it is extremely mathematical and computationally intensive. In this lecture, we will review current status of downhole sensing technology, explain the available models and approaches for interpretation, and present field application examples including production profiling, horizontal well flow control, matrix acidizing optimization and multi-stage hydraulic fracture diagnosis. The lecture is based on publications by the author and other SPE publications. The lecture illustrates the power of DTS as a tool for production problem diagnosis and well performance optimization.
