A high quality annular pack is critical to the reliability of sand control completions. Issues related to the quality of the annular pack and its interpretation play an important role in bean-up strategy, well performance, sand production and water influx complications. A detailed analysis of frac pack pumping practices, procedures, and downhole flow direction during the reverse out was performed across a wide subset of frac packed wells. It is shown that interpretation of radioactive tracer logs combined with pumping data play an equally important role in assessing the quality of the annular pack and potential mechanisms that could lead to an inadequate annular pack. The presentation will include case histories identifying best practices to achieve a consistent high quality annular pack.

Over the last five years, innovators have driven the development of several umbilical-less technologies to improve efficiency in well completions. To meet this demand, the industry has introduced both electric-hydraulic and less complex mechanical solutions. In this presentation, we highlight a technical solution that uses mechanical mechanisms to achieve all required functions of the tubing hanger running tool. We will present specific design solutions, functions, the underlying design basis, and qualification process. Additionally, we will share operational conditions and field experience gathered from 40 tubing hanger runs since the tool’s first field deployment in March 2022.

Completions in deepwater subsea environment are inherently complex, and many specific challenges are frequently overlooked when approaching these types of wells. Subsea well completions introduce significant technical and operational demands driven by the remote location of the wellhead on the seafloor, the harsh conditions of deepwater environments, and the limited ability to intervene once a well is placed on production. This presentation provides a structured overview of these design and execution considerations, emphasizing how floating rig dynamics, deepwater environmental effects, and specialized subsea equipment requirements shape the engineering decisions behind designing and deploying reliable, long life subsea completions.

As North Sea O&G reached 50-years (2015) it was clear that continued resource development would require step-changes in the efficiency of completion approaches. Low-cost, multi-stage and efficient deployment of conventional fracturing in an offshore, platform/rig-based, dry/wet tree environment was desperately required. At that point, a strategic journey began, with a suite of steps since taken, that have delivered real cost-effective access to stranded/challenged reserves. This presentation will recount that journey and indicate the opportunities and future for mature basins that await as a result.

Open-Hole Gravel Pack (OHGP) completions are being deployed in the Gulf of America (GoA) to deliver robust sand control and high productivity in unconsolidated, long horizontal reservoirs where cased hole designs are less effective. This campaign integrates advanced techniques—including pre-drilled liners, Managed Pressure Drilling, and wellbore strengthening—to address depleted formations, low fracture gradients, and complex operational risks. The result is one of BP’s most technically challenging completion programs, offering key lessons for future deepwater developments.

In achieving the low-cost technology to develop fields where limited reserve volumes are insufficient for fracpack with screen assemblies, screenless fracpack with smart fracturing system has been applied in Field B where fracpack have been the preferred sand control methods. This is the first debut of screenless fracpack in cemented monobore utilizing smart fracturing system in Asia Pacific. This presentation discusses the design intricacies, implementation and execution, production performance, and future recommendations.

Deepwater Assets in the Gulf of America (GoA) have been challenged in recent years by major production deferrals due to fail-close incidents of nitrogen (N) charged tubing retrievable surface controlled sub-surface safety valves (TR-SCSSVs). Remediation for these failure events were typically managed via a workover operation which required a mobile offshore rig unit (MORU) at considerable cost. The industry offers other alternative wireline retrievable valves, but these are all subsurface controlled designs that are not currently approved for use in GoA subsea wells due to federal regulations. This multidisciplinary project seeks to prove an alternative low cost and reduced scope solution for remediating production deferrals due to N2 related TR-SCSSV closures. A key enabler is the usage of a Light Well Intervention Vessel (LWIV) to perform the operation, which normally has greater flexibility in response time and scheduling of operations. With the availability of the LWIV, a WR-SCSSV intervention installation can cost approximately 50% and 30% less than the cost of a workover to replace a failed TR-SCSSV on a horizontal and vertical tree respectively. The eventual installation of the WR-SCSSV was performed according to plan, achieving the objectives of not only restoring the well to production, but installing a functioning well barrier element to further manage the life of well. Furthermore, this has unlocked well intervention and well management capabilities, previously unavailable in Deepwater Subsea environments of the GoA and beyond.

Operators face considerable operational challenges in deepwater completions, particularly in sand-control environments in managing high-pressure formations, maximizing stimulation rates and proppant volumes to ensure zonal coverage while reducing operational risks and costs. Traditional single-trip methods for sand-control wells often involve complex logistics, increased cycle times and project costs. Superior’s field-proven next generation Multi-zone Single Trip System, with an enhanced barrier valve and other proprietary features — delivers a streamlined, cost-effective solution. Integration of a barrier valve into the system, eliminates the need for a dedicated intermediate trip. This system enables treatment of multiple zones per well in a single trip at industry leading stimulation rates and volumes. It has consistently delivered outstanding performance in an ongoing high-profile, ultra-deepwater Paleogene project in Gulf of America, reducing risks, costs and enabling an early realization of returns for the operator.

Several ultrafine fields in the operations area were opportunities for development using existing facilities. However, previous failures and complex reservoir characteristics among other challenges demanded for an alternative sandface completion solution. SMP (Shape Memory Polymer) conformable screen ranked as the best solution for this project, based on multiple factors such as ease of installation, productivity and expected reliability for this type of reservoir. Rock geomechanical analysis and extensive qualification testing were key for successful planning and execution. Four wells were completed. Flow back and production results demonstrated completion success and allowed further consideration of similar fields.

Horizontal Open Hole Gravel Packing (HOHGP) has developed into a standard technique for complete high value wells both on and offshore. In this talk we will review the good practices that have evolved and why it is important to use them. In most cases, the best practices and lessons learned will be demonstrated using actual case histories.

Speaker(s): Sanjay Vitthal

An alternative lower completion concept, referred to as a High Angle Multi Fractured (HAMF) wells, is discussed. The system is designed for improved economic development of low mobility reservoirs in deep-water subsea environments such as the Paleogene/Lower Wilcox in the Gulf of Mexico. The talk covers the business drivers, system benefits, system design, qualification testing, and its functioning. Results from a field trial to mechanically test the system are shown and discussed.
