Frac Field Planning & QA/QC
The backbone for any successful fracturing and stimulation operation is the QA/QC program behind it. In order to achieve all frac program objectives, every single part of the operation needs to be up to spec. Robust operating procedures also need to be in place to achieve design requirements.
Viking Engineering provides the operator with a comprehensive QA/QC plan tailored to each project to assure the success of the fracturing and/or stimulation operation. Viking’s team possesses a broad experience in all aspects of the QA/QC implementation program from material selection - including frac fluid, water, proppant/sand, chemicals - all the way to pumping and monitoring equipment.
We fully believe that in order to complete a successful operation, the collected data needs to be accurate and precise to be able to properly evaluate and further optimize the next job. For this reason, as part of this program, Viking provides full support on the required data acquisition plan and data analytics.

This calculator calculates the change in length of pipe hanging in the hole due to tension, ballooning, buoyancy and thermal effects.
The recent global over supply of crude oil and soft demand has resulted in oil companies shutting wells in to prevent destroying value and to protect their balance sheets. The time frame, until production startup becomes economic, is uncertain and therefore, it is imperative that appropriate actions are taken to maintain and manage the integrity of shut-in wells and associated delivery systems.
The time frame, until production startup becomes economic, is uncertain and therefore it is imperative that appropriate actions are taken to maintain and manage the integrity of the available Installed Production Capacity during shut-in.
This GATEKEEPER article focuses on the prediction, prevention and remediation of liquid loading, including discussion of liquid loading analysis.
Triaxial evaluation of loads is used extensively for casing and tubing string design and analysis. The paper presents a method of determining the triaxially based collapse strength of casing and tubing subjected to simultaneous axial and internal pressure loads.
Efficient access to multiple permeable natural gas zones located in deep, over pressured, and extremely corrosive environments presents a challenge for South Texas operating companies.
Vacuum insulated tubing (VIT) has been used successfully to mitigate the potentially harmful effects of annular pressure buildup (APB). In a recent deepwater installation, the subject well had lost alternate APB mitigation capability through a series of events. VIT was then chosen as the only viable technology.
A method is presented such that two parameters can be used to fully describe the thermal characteristics of a tubing string undergoing an injection or production process.
Artificial lift methods transfer energy to the produced fluid with the objectives of reducing the fluid density and the pressure head or boosting the flowing pressure.
A finite difference model was developed and used to simulate transient heat transfer in wells undergoing injection and production processes.
The flow of metal during Friction Stir Welding is clarified using a faying surface tracer and a nib frozen in place during welding. It is shown that material is transported by two processes.
This paper was prepared for presentation at the SPE Applied Technology Workshop on Risk Based Design of Well Casing and Tubing held in The Woodlands, Texas, U.S.A., 7-8 May 1998.
Deepwater high pressure, high temperature (HPHT) drilling environments present difficult challenges to well engineers.
This work is a discussion of how the limit performance is being defined and quality systems are being revised for API connections in accordance with the objectives of the LRFD method for OCTG.
When tubing heated by hot formation fluids contacts colder fluids entrapped in the annulus, the result is fluid heating and pressure buildup. Proper well design is critical in subsea wells.
New integral joint connections can withstand greater loads, increasing their range of applications. The use of IJC casing can allow a slimmer well to be drilled, reducing total well costs.
A wide range of aluminum alloys and other metals and alloys, particularly dissimilar materials, have been friction-stir welded in this study.
This paper describes research efforts and technology development associated with the next generation of high pressure, high temperature (HPHT) well designs.
Friction Stir Welding is a relatively new technique for welding that uses cylindrical pin or nib inserted along the weld seam.
This paper describes an investigation into the relationship between design criteria (minimum acceptable design factors and maximum acceptable number of pipes) and cost.
This GATEKEEPER discusses an effective subsea tree PWV (USV) leak test method. The test can be done quickly – entire test time is about 15 minutes, including the 5 minute monitoring time.
Annulus Pressure Management refers to an engineered approach ensuring that casing annulus pressures do not challenge the well’s integrity during the life of the well.
Determination of the proper 13Cr grade for sour service involves the investigation of domain diagrams, and often requires further fitness-for-service testing.
