Market Shift to Horizontal Wells and Larger Jobs Haynesville Example


I. Deep shale plays requiring long laterals

II. Pressure pumping equipment availability

III. Limited wellsite location sizes

IV. Strong environmental scrutiny

V. Need for effective water management strategy

North America has 25% of worldwide reserves but 75% of pressure pumping equipment

Global Gas Markets and Pressure Pumping Equipment


I. Plug and Perf

Perforate several clusters, isolate with drillable bridge plugs

II. Sliding Sleeves

Annular isolation using ECPs (ie: Swell Packers, etc)

Horizontal Frac Completion Methods


III. Coiled Tubing Assisted PinPoint Fracturing

Frac with coiled tubing in the well, isolate zones with sand plugs

Main Types of Horizontal Frac Completion Methods (CONTINUED)


Plug and Perf Method vs. PinPoint Stimulation

A typical Haynesville Plug and Perf frac:

5 clusters per 50m interval 5 shots per cluster 80bpm 19,600 HHP @ 10,000 psi Rate per perf: 3.2 BPM/perf 2 frac intervals per day

Pinpoint stimulation requires less equipment and a smaller footprint

A typical PinPointStimulation job with CTU:

1 cluster of perforations per job 3 hydrajetted perforations per interval 30bpm 6,250 HHP @ 8,500 psi Rate per perf: 10 BPM/perf Multiple intervals per day Aggressive frac designs

creating a compelling sustainability option for our customers

Water Treatment Services UV Bacteria Control

Greener FracFluids

Improved Environmental Performance Recycling Produced Water and Greener Frac Fluids


Produced Water Recycling

Purpose is to clean water in order for use in fracturing operations

Electrical charge coagulates suspended matter

Handles wide variety of source waters (TDS range = 100 to 300,000 mg/l)


On-the-Fly Bacteria Control

Ultraviolet (UV) light treatment kills bacteria

Used inline with frac spread up to 100 bpm

Eliminates the need for common fracturing biocides


Sourced from products used in the food industry

Systems developed for slickwater, linear gel, or high viscosity crosslinked system

Applicable for reservoirs up to 150 deg C

Can be mixed in a variety of base mix waters, including produced water

Greener Frac Fluids
