First and foremost the units built by OGW are all designed and robust enough to hold up in the field. Units are transported in standard shipping lanes and then final basic assembly connections are made on site. Units can be customized for permanent installation by client request.
CLWM - Closed Loop Water Management Plant
The permanent plant site is designed to take in dirty water through pipeline or trucked volumes, similar to a traditional SWD location. The plant would charge a per bbl fee to accept water from operators and then clean the total daily volume accepted. The cleaning process produces a clean softened brine which can then be purchased and immediately picked up by the same trucks that brought in the dirty water.
Truck costs and traffic are significantly reduced for the operator because they are no longer paying for empty transit time. The plant includes a truck wash out station, the wash water from which, is processed right along with all of the other dirty water accepted at the site.
The water cleaning process also produces a market ready lime slurry from the softening process which can be used in multiple industries. In addition, the process returns a small percentage of fresh water that is safe for surface release or irrigation purposes.
Once an MWR unit has completed a string of well recycles, the operator has the option of returning the last volume of dirty water to our CLWM location instead of traditional disposal. Plants may be a permanent installation on OGW permitted property, or they can be built as semi-permanent operations on partnership properties during times of strong market demand or scarce water supply.
MWR - Mobile Water Recycling Units (14K bbl/day capacity) designed and deployed for use with the following:
- Well Site Central Hub - Temporary or lay flat lines can be used to create a hub and spoke system to connect a group of nearby wells in order to consolidate water volume to reach MWR efficiencies.
- Well Workover String- Initial well is treated with traditional water sources, then after workover, water is recycled with MWR unit which produces clean standard brine which may be used to workover the next well in the string, - eliminating the need to purchase additional fresh water and transport/dispose of the 'dirty' water. At the end of the string the dirty water is brought back to the CLWM plant (see below) for final cleaning.
- Regional Water Collection Site - In some areas regulation allows for the collection and storage of water in tank batteries or pits. Water can be collected for a period of time until the facilities reach capacity at which point the MWR units can be deployed to recycle the volume in storage, bringing the available capacity of the collection site back to 100% for the next season, job, etc.
- SWD Site - Traditional SWD sites are limited by their permitted well capacity or pressure. With the addition of a MWR unit, an SWD operator would immediately increase their intake capacity by 14K bbl/day and increase the lifespan of the SWD well by decreasing the time and expense of costly repair and replacement of pumps and gear.
We pride ourselves on a results-oriented approach which relies on consistent output and quality control through independent lab verification at every stage.
We work every day to perfect water filtration in all its forms; keeping this valuable resource healthy and viable to meet the demands of the O&G industry now and in the future.
OGW's key difference in the market is that our technology and methodology produces a consistent clean brine during operations. This is important so that operators and frac companies can plan ahead to create effective chemistries using a standardized brine versus fresh water. This reduces the need to continually purchase and truck fresh water for each frac and/or workover job. OGW's standard offering is a 10lb. brine, but customized options are also available.
The flexibility of the unit is key to its effectiveness for the field. Each play, zone, formation, region, client, and even well has different contaminants and different re-use goals/needs. OGW's MWR units can be tailored to meet the needs of each client. Components can be added, deleted, and/or re-sequenced based on the type of water and contaminants being treated and SCADA systems can be configured to produce usable data for each client.
At Oil & Gas Water Technology Group, we've taken our collective experience in closed loop salt water control to create our own methodology to meet market demand for a clean, soft, industry usable brine.
The key to effectively cleaning any set of water or effluent is layering the steps and sequencing them so that you get the most bang for your buck. The units transition between mechanical, chemical, and biological options as needed so that each step reaches its maximum efficiency. All units have an optional final step of adding desalination to take the final product to clean fresh instead of clean salt water.
