General Meeting: Proppant Placement in Complex Secondary Shale Fractures - A New Frontier for Fracing Fluids

ABSTRACT of Presentation

Operational practice with hydraulic fracturing has evolved from using conventional linear gels (mostly guar and derivatives) to polyacrylamides (slickwater). The latter is currently the dominant trend, providing low cost friction reduction, low viscosity and simpler chemistry needed for high pump rates, opposite to guar systems. Only drawback: poor proppant suspension. The physical structure of rocks within so called Low Mobility Plays make proppant placement a major issue due to very small fracture widths limiting access to proppant sizes commonly used.

A novel fluid additive that shows lower viscosity and similar friction reduction as polyacrylamides has been tested to evaluate its suspension properties. API 13 rheology was measured and settling tests were conducted using Multiple Light Scattering technology, which makes simpler and more accurate follow up of settling processes in transparent, translucent, and opaque media, providing data on average particle size and hydrodynamic parameters such as velocity of a moving front of decanting particles.

It has been established that proppant size and load suspension is directly related to the novel additive concentration, but no direct relationship with viscosity. This means that lower additive concentration can suspend smaller size proppants. Results show that suspension of proppants from this study is a time dependent process, it could be very short lived as in the case of conventional FR’s and some HVFR’s, or it can be extended from minutes to several hours or even days, after using the appropriate dosage.

Registration & Walk-ins

All attendees are encouraged to register and pay online for this event. This is a more efficient means of registering for the event and enables the registration process at the meeting to move much faster. Walk-in space is available on a seat-limited basis at a fee $5 more than the on-line registration fee.

Parking for this event

The TOTAL Plaza building (1201 Louisiana Street across from the Houston Hyatt Regency Hotel) is connected to the downtown Houston tunnel system. Using the tunnel system, those working downtown can walk to our meeting in air-conditioned comfort.

If you will drive to this meeting, the following summarizes available parking:

The image above shows how to access the valet parking area at the new location of the Petroleum Club. Enter from Milam Street and exit onto Louisiana Street. Parking fee for this valet parking is $15. Be sure to get discount parking sticker at registration table if you use this valet parking service.

Surface parking lots are available to the south of the TOTAL Plaza building (between this building and the former EXXON Building), including one surface lot adjacent to the TOTAL Plaza Building - pay at meter (cost ~ $9). Other surface lots in the area cost $8 - $9 and they frequently are full by mid-morning.

Parking is also available in the Hyatt Regency Hotel parking garage across the street. Prices vary depending on time in the garage. Cost for 2 hours of parking is $12. Parking is also available via valet at the Louisiana Street entrance of the hotel. Cost is about $10.
