I’ve just released an exclusive set of materials covering efforts to resolve the potentially crippling threats posed by Sustained Casing Pressure (SCP) in production both onshore and offshore. These materials provide a comprehensive overview of the challenges of dealing with the issue and what can be done to better diagnose at-risk wells.
The problems associated with SCP are felt across the offshore oil & gas industry, from operations in the Gulf of Mexico to right around the world. How to prevent it from occurring – and then recurring, as it often can – has become a pressing issue, especially as it’s not always possible to determine where the pressure source originates from.
Now, I’ve been able to release new information from renowned “Well Doctor” Dan Gibson, who offers expert insight into how to tackle the problem, and suggests that well operators adopt monitoring technology so that their production is extended and their assets protected.
The prevalence of SCP has been made known by a number of studies and reports in recent years. They point to the large-scale threat in the Gulf of Mexico, where it’s estimated that more than 8,100 wells are at risk due to symptoms that have emerged. Not all wells were adequately protected with casing that can hold back the pressure, and so there’s a real risk in the region of environmental pollution if disaster strikes.
Gibson, who is a highly experienced well integrity engineer, says that tighter government regulations in the past number of decades has meant well operators have been forced to improve the safety of their wells, and their reliability. They do this through monthly monitoring, daily checks and working out the SCP risk of each well – and working how to manage it if something goes wrong. But, says Gibson, a “deeper, more rigorous, analysis approach” is needed to adequately deal with the problem, especially at a time when many wells are already several decades old and are reaching the end of their lifecycle.
One of the difficulties in properly assessing and managing SCP, however, is the ever-smaller margins that oil & gas companies are working under, particularly at a time when oil prices have been plummeting. It can essentially mean that real SCP issues are put on the backburner as companies seek to cut back on costs amid lower earnings.
Meanwhile, Upstream Intelligence’s material release also contains expertise in the area from Professor Andrew Wojtanowicz of Louisiana State University, who has been extensively involved in early studies on the problem of SCP.
Professor Wojtanowicz presents an overview of the latent hazards of an ineffective SCP risk evaluation programme, and he outlines current methods of the remediation of gas migration. Operators can also gain insight into the science behind SCP diagnosis and find out about the professor’s “gravity displacement” method. His research has developed a viable “hydrophobic kill fluid” that should be of interest to all in this sector – details of which are available in the Upstream Intelligence whitepaper now available.
We believe these materials will help both onshore and offshore oil & gas operators in the Gulf of Mexico and elsewhere take preventative action against the threat of SCP, for more productive rigs and protection against environmental catastrophes.
It’s clear that with this information, oil & gas companies who make use of it are now in a position to better protect their drilling operations and also to ward off pollution problems. We encourage all operators to read our materials so that they can take effective action moving forwards.
The next steps on the battle against critical well integrity risks such as SCP will feature heavily at this year’s pioneering 2nd Annual Well Integrity & Lifecycle Management Conference 2015, which will take place at in, Houston TX, June 16-17.
Upstream Intelligence is proud to host a ground-breaking meeting that will allow you to efficiently maintain production levels, optimize investment and extend operational lifetime of your wellbore by honing your integrated well integrity strategy.
