This calculator calculates the change in length of pipe hanging in the hole due to tension, ballooning, buoyancy and thermal effects.
This information provides insight to aid in preventing common failures and improving industry practices to reduce incident rates in addition to saving time and money.
This GATEKEEPER article focuses on the prediction, prevention and remediation of liquid loading, including discussion of liquid loading analysis.
Casing and tubing that are subjected to combined loads have higher collapse strength than previous formulas would predict, permitting the use of thinner walled, or lower strength, pipe than formerly required.
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.
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.
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.
This paper describes research efforts and technology development associated with the next generation of high pressure, high temperature (HPHT) well designs.
Material selection is a nuanced process. A primary assessment based on environmental and operating conditions enables identification of outright inappropriate materials and allows a general selection to be made.
Viking has the expertise to help operators better understand past well failures and frac performance by working together to develop improved frac designs and execution.

From fracture design to execution and post-treatment analysis, Viking’s approach offers the operator technically supported decisions when conducting fracturing and stimulation operations.
Viking Engineering provides onsite support for all fracturing and stimulation operations. The onsite Viking team ensures that operations are executed as it was designed and planned while making sure to achieve the project objectives. This gives our clients peace of mind throughout the process.
Surface operational temperatures >302°F (150°C) makes well design, materials and equipment selection critical for Geothermal wells. Viking Engineering’s knowledge and expertise helps to deliver your required solutions.
Provides fit-for-service evaluations, testing and analysis for evaluating complex downhole failures, pipeline failure investigations and forensic services for midstream and downstream clients and also provides services to the renewable energy sector.
Viking Engineering has performed many materials selection projects to help operating companies produce oil and gas safely and within budget.
The Viking team merges the mechanical and dynamic thermal-hydraulic aspects to bring a true systems approach to annulus pressure management.

Failure analysis is a critical process in determining the physical root causes of problems. The process is complex, draws upon many different technical disciplines, and uses a variety of observation, inspection, and laboratory techniques
The Viking QA Team provides experienced and competent QA & TPI Inspectors around the globe, providing mill, post mill and vendor surveillance on critical casing and/or tubing strings, drill pipe, line pipe, downhole engineered equipment and accessory items.
GATE follows a similar methodology to threat identification in risk assessment (e.g. FMEA), and analyses the relations between possible causes, and prevention and maintenance measures to highlight the cause(s) to be addressed.
Provides fit-for-service evaluations, testing and analysis for evaluating complex downhole failures, pipeline failure investigations and forensic services for midstream and downstream clients and also provides services to the renewable energy sector.
The Corrosion and Materials Team for oil and gas developments and water and gas injection systems forms one of Viking’s core oil and gas engineering services.
Viking can help you design and implement a tailor-made Risk Based Inspection (RBI) Program.
GATE can improvise, implement and manage a cost-effective plan for your asset to ensure safe and continuous operation.
Integrity engineering consulting starts at design stage where the corrosion control strategy is laid-out to reach the desired service life with minimum interruption.
Viking uses our systems engineering, materials and integrity management, commissioning and operating knowledge of onshore and offshore water injection systems around the globe to reach a solution that is optimized to the need of each Client and each asset.
Our engineering support extends to developing and coordinating corrosion testing and inhibitor qualification programs, to validate both material and chemical selection choices.
At Viking, we take flow assurance engineering and modeling to operations. By using a systems engineering approach, Viking addresses the challenges from modeling to development of operational strategies to optimize flow assurance engineering in the production system. Flow assurance modeling is a key aspect of engineering design work, especially in deepwater oil and gas developments.

At Viking, Flow Assurance engineering and modeling is designed to assist in project decision making.
Injection into hot and high-pressure deep water reservoirs is often constrained by concerns associated with fracture propagation.
Preparing for operation of a major oil and gas facility is a daunting task. Viking provides standard operating procedure (SOPs) generation, maintenance planning (CMMS, Spares), FMEA and RCA studies and Control System Tuning and HMI Screen Development.
Operations Readiness systems developed late in a project and in silos can’t reach the potential of becoming the powerful tools that they were developed to be.
The main difference between the GATE Stream-Based HAZOP and a typical HAZOP is that we define nodes based on ‘streams’.
Viking uses an innovative phased approach. High level SOPs are developed early based on the PFDs. These are then matured to mid-level and finally to detailed procedures as the project matures.
We have a broad knowledge in generating plans for the initial startup of wells, subsea tie-backs and new platforms.
Life extension is a comprehensive review of a facility or vessel to determine if improvements are required, and what is needed to extend the operational life.
