PROS Incorporated provides complete flowback services to the oil and gas industry. Our 24-hour flowback service prevents environmental spills and lost production with a focus on moving the well safely from completion to production. PROS Incorporated Technicians monitor the well, including separator equipment, measure flowback, prevent spillage by arranging for hauling services, shutting the well in, or switching tanks; and provide a daily report.
Pressure Volume Temperature: PVT sampling
Pressure volume temperature (PVT) analysis is the process of determining the fluid behaviors and properties of oil and gas samples from an existing well. PROS, Inc. have experienced technicians trained in PVT sample collection working with Core Laboratories / Pencor.
The duration of conditioning a well depends on the volume of altered fluid around the perforations as a result of producing the original fluid below its saturation pressure, and the rate at which the altered fluid is produced. The following parameters should be continuously measured during the well conditioning program: reservoir pressure, reservoir temperature, wellhead pressure, wellhead temperature, separator pressure, separator temperature, separator or stock tank liquid rate, separator gas rate, water production.
Sampling should be done only after the well has been cleaned and free of completion fluids; producing at least ten times the volume of the completion fluid. If a well was not sampled before reservoir pressure declined below the saturation pressure, a development well in a virginal section of the reservoir should be considered for obtaining representative samples.
Flash Liberation Sampling
Flash liberation is a process involving a sudden pressure change that causes the crude oil to quickly separate or “flash” into in an oil and gas mixture. PROS, Inc. have experienced technicians trained in Flash Liberation sampling collection and can provide three phase separators for the sample collection.
Live Density Collection
PROS, Inc. offers a process for collecting live densities under pressure for density analysis. PROS, Inc. laboratory then runs the samples through a densitometer for live oil and water density analysis.
Gas, Oil, & Water Sampling
PROS, Inc. offers a trained technicians for collecting gas, oil, and water samples. It’s critical when taking gas, oil, and water samples to follow API protocol for proper collection, handling, and processing. PROS Laboratory can also provide the following laboratory tests.
PROS, Inc. Laboratory Test Analysis
PROS, Inc. perform the following Laboratory test in the field and at the Bakersfield laboratory making sure to adhere to all company policies and procedures. PROS, Inc. uses API Field Sediment & Water Standard Chapter 10.4 for cuts and Manual of Petroleum Measurement Standards (MPMS), Chapter 9.1 Standard Test Method for API Gravity of Crude Petroleum and Liquid Petroleum Products by Hydrometer Method.

PROS, Inc. is a California State Water Resources Control Board
Designated Third Party Contractor for SB-4 Water Sampling
California has been producing oil and natural gas (gas) for over 100 years and currently is the third largest producer in the United States. The majority of oil production in the state is concentrated in the southern San Joaquin Valley, but oil production also occurs in the Los Angeles and Central Coast areas.
The volume of oil and gas that is produced from an oil or gas well may be enhanced by using well stimulation treatment. Well stimulation treatments include processes such as hydraulic fracturing (also known as fracking), acid fracturing, and acid matrix stimulation. Well stimulation methods involve pumping a mixture of liquid, chemicals (which can include acid), and/or sand down an oil or gas well under high pressure to fracture or dissolve portions of the rock formation. The process creates voids whereby oil and gas can more easily flow toward the well.
In response to concerns over potential impacts of well stimulation activities on water resources, Governor Brown signed Senate Bill 4 (SB 4) in 2013, which amended the Public Resources Code and Water Code as they relate to oil and gas well stimulation activities. This legislation created new requirements for oil and gas operators, the Division of Oil, Gas, and Geothermal Resources (DOGGR), the State Water Resources Control Board (State Water Board), regional water quality control boards (Regional Water Boards), and other agencies to implement when performing or permitting well stimulation treatments.
The State Water Board is required to designate one or more qualified independent third-party contractors to perform property owner requested water quality sampling and testing (Pub. Resources Code, §3160, subd. (d)(7)(B)).
