Why pre-drilling through a template is back on the agenda in the offshore industry
2. PROVEN TECHNIQUE
Since the 1970s many operator’s fingers were burnt with the first versions of well tiebacks which were misunderstood, less extensive and coupled with bad experiences. Things have now changed for the better with companies, such as Claxton, offering bespoke templates to operators – taking into consideration all the construction and drilling interfaces as well as relevant environmental and soil data.
Using Claxton Engineering as an example, the company’s templates now support over 55 major developments around the world showcasing that the application is robust and tailored for any operator working offshore.
Time is money and money is scarce. Given the current economic conditions, operators can set up a rig safely and cheaply in the time a pre-drilling template can be designed and fabricated.
Whilst bespoke templates and asset survey’s require time to complete by the engineering service you’re working with, the turnaround from design to installation can be a matter of a couple of months rather than years to have a platform ready for installation.
The delivery time of the platform can then determine the number of wells to be pre-drilled. Therefore when the jacket and top side are installed, the pre-drilled wells can be tied back to the platform and drilling resumed meaning operators can begin production sooner – making it one of the most cost-efficient applications in the offshore industry.
