How do you keep your SWD Data and profits from going downhole?

When operating a modern Salt Water Disposal well, there is no disputing that data management and invoicing are critical to the plant’s profitability. Operators must know the origin, volume, truck, time of delivery, and date for all of the loads entering the system. This identification information can be entered by the SWD operator or by the truck driver in either a paper ticket format or a touch-pad computer screen on-site. SWDs have unique requirements for accounting, administrative duties, and mandatory reporting to the state or Tribe. Many owners find it frustrating when trying to find a data management system that is flexible and able to accommodate the demands of a SWD.

With today’s market volatility, it is extremely important to streamline data management processes, reduce… Continue reading

Oil Skimming Operation

Introduction

SWDs receive waste water from oil and gas exploration and production activities. Waste water usually contains significant quantities of crude oil entrained in the fluid but the word “significant” can mean a large fraction or a barely perceptible trace. The amount of oil and the ability of the SWD operator to skim the oil will determine the economics of crude oil production from any given SWD. The process can be done many ways and may involve simple settling in the tank battery and enhanced settling by way of a “gunbarrel” separator or a centrifuge. The more common technologies used in the oil field are discussed below.

Skimmed oil sales add to the revenue of many SWDs around the country. Crude oil recovered from… Continue reading

Filter Systems Applicable to SWDs


Introduction
Waste water injectate may contain a significant volume of particulate material when it is delivered to the SWD. Initial filtering and settling within the tank battery will remove most of the particulates from the stream. Final filtering prior to injection may be needed. While some SWD operators do not use filters prior to injection, there are several alternative technologies that can easily be applied to initial and final filtration in order to protect the injection zone and extend the well’s useful life. These technologies are discussed below and can be used for either initial or final filtering steps.

 

Filtration with Replaceable Filters
The simplest setup for filtration involves a steel vessel with several internal filter-pods that accept single-use fabric filters or perforated, re-useable… Continue reading
