... Abstract Openhole gravel pack completions excel in unconsolidated regions due to their high flow area and efficient recovery with a low drawdown. Openhole water packing, utilizing low-viscosity brines for proppant transport, relies on swift local velocities. In horizontal wells, the process...

...Mechanical Completion This phase comes after construction and installation. Mechanical completion involves inspecting and testing all machinery, equipment, and site construction. The goal is to ensure everything matches approved drawings, specifications, and project requirements, making...

... Abstract The cardinal objective of working over an oil or gas well is to increase the well’s production performance. It involves stimulating existing production zone(s) with impaired production due to skin or other near-wellbore damage situations, pulling an existing completion, accessing new...

... alternative, despite inherent challenges. Comprehensive risk and uncertainty mitigation analyses were conducted, leading to the development of a robust and safe HWU work module. The inaugural deployment of the HWU on a shallow offshore well's initial completion was successful and incident-free. Encouraged...

... wells drilled at the crest of the structure to target gas for gas cap blowdown were observed to log a shallower GOC than the initial GOC. This was also corroborated by well test results on a completed gas-cap blowdown well. The well was recently completed across the original gas column. Fluid sample...

... flowlines. The production wells were completed with Frac-Packs for sand control and Intelligent Well Completion (IWC) systems to provide zonal information and control for effective simultaneous production of multiple zones per well. Several years after the start of production at Field X, failure...

...%). Reservoir Development History Production from the reservoir commenced over two decades ago from one completion. Later, two additional wells were drilled to sustain production in the reservoir. While the lower unit was only produced by one of the three wells, the upper unit was produced from all three...

... to pay little attention to designing and maintaining optimal gas lift systems. Some unique considerations are required for a dual gas lift system where both strings in a dual completion are on gas lift. Using a case study, this paper highlights key investigative questions and assessments to understand...

..., backflow and crossflow are major integrity problems in several injection wells in the targeted field, especially with fines migration and accumulation inside the lower completion during sudden or prolonged well shut-in. Formation solids are normally resident in the reservoir during the steady injection...

... The lower completions phase was designed to be executed in 4.7days, with a target expectation of 3.7days without any downtime. The initial objective was to expand ESS screens with the Axial Compliant Expander [ACE] Tool to the Expandable Bottom Connector [EBC] and retrieve the tool to surface...

All these focus on the completion design of the main bore, lateral bores, and junctions that connect the lateral and main bores. Hence, one of the factors to consider in designing multilateral wells is the junction type, which depends...

... Abstract Recent papers describe successful Single-Trip Completions (STC) operations carried out offshore Nigeria and other locations and has successfully shed light on implementation of this advanced technology, which represents a step change in operational efficiency. However, the cost...

It, therefore, becomes imperative for the completions planning team in collaboration with other relevant stakeholders to establish an "execution-friendly" reverse-out decision and communication protocol that will prevent...

... production rates with sand control. In order to achieve these goals, the sand control methodology deployed is the Open Hole Gravel Pack (OHGP) pumped through Concentric Annular Pack Screen (CAPS) system. This completion methodology has similar comparisons to the AX field completions where 19 completions...

... Abstract Unconsolidated sandstone formations are normally completed with one form of sand control or the other. The aim is to manage sand production as low as reasonably practicable and protect well and surface equipment from possible loss of containment. There are about 8 broad types of sand...
