HPHT Services

HPHT projects are challenging and carry greater risks and rewards than conventional drilling projects. Since 1996 Salos Sunesis Limited (SSL) has supported Oil and Gas Majors and independents successfully deliver their HPHT projects.

As an organisation we provide an end to end service across the full HPHT planning and delivery life cycle including; project planning and setup, drilling programme review & optimization, DWOP & HAZID facilitation, development and review of well control manuals & procedures, operational readiness audits and the provision of training and coaching. All our services are designed to ensure the safe and efficient delivery of the well.


The coaching provided by Salos Sunesis improves performance in the execution of the well programme, enhances the core competencies and practical knowledge of the team. Our HPHT Coaches are typically deployed at the start of the 12 ¼” section, or earlier, to close any gaps and improve performance and awareness of the rig personnel prior to reaching the HPHT section.

Valuable rig time will be saved through their deployment and our unique approach to coaching and as a result we bring a number of significant safety and performance advances to our clients drilling operations.

Our coaching team have 24 hour access to our Project Asset Coaching Systems (PACS).  This support system has been developed by SSL to ensure that our onsite coaches can maximise their impact, accelerating the competence and performance of the the crews that they are training and coaching.

Training and accelerating competency at the worksite

We have a wide range of training programmes to meet the needs of our clients. These can be delivered in class room or rig site. We regularly deliver training to shore based engineering teams, as part of their preparation and planning for drilling an HPHT well. As an integral component of the onsite coaching we further enhance the competency of the crews by providing a series of intense training modules. These short modules are typically delivered at the end of shifts and are further enhanced with practical drills, daily check sheets and “coaching moments” at the worksite. These positive interactions are designed to improve operational awareness, knowledge and performance.

Over the last two decades Salos Sunesis have become the preferred technical advisor to many clients who have come to understand the significant impact our involvement can bring.  

“We used Salos Sunesis as our HPHT advisor on our Romeo well in the North Sea. This was the first HPHT well we had drilled in the UK section of the North Sea. The well was in partnership with TOTAL. As it was our first well we wanted the best resource for HPHT training in Aberdeen and Salos Sunesis came to us highly recommended. I am pleased to say they did not let us down. They organised our crew training, helped with the HPHT manual & went offshore and supported our efforts. All in all a great job. I can recommend Salos Sunesis and will be using them again on future projects.”
