... existing well in Offshore Mahakam field become a base case by targeting both shallow reservoirs with sand control requirement and deeper reservoirs at consolidated sandstone. Conventionally, side-track wells are drilled in two separated section to allow Gravel Pack completion inside 9-5/8" casing...

... Abstract One of the major technical challenges to this project was placing horizontal open hole gravel packs (HzOHGP) within the narrow pore pressure to frac-gradient (PPFG) margin in the target reservoirs. This paper addresses the steps taken to overcome this challenge. To maximize the use...

... Abstract Openhole gravel pack is the preferred completion method of sand control in unconsolidated deepwater formations with sanding tendencies. The design phase of an openhole gravel pack treatment spans drilling of the reservoir section, wellbore preparation, sand screen installation, gravel...

... Abstract Achieving complete and efficient gravel packing is the primary objective when tasked to install an effective sand control completion. This paper describes the challenges faced during the selection, design, planning and execution phases of the open-hole horizontal gravel pack...

... Abstract The Badamyar project is an offshore gas field located 220 km south of Yangon in the Republic of the Union of Myanmar. In February 2017, four gas wells were successfully drilled and completed using horizontal openhole gravel packing in the Badamyar gas field. The downhole completion...

... to some degree are likely to happen from the carbonates in this field. To minimize the risk of solids production, an openhole gravel pack (OHGP) system was designed and deployed. Horizontal OHGP involving screens equipped with shunt tubes for alternate packing are commonly deployed in unconsolidated...

... in lower main until deep zone. Handil shallow zone consists of multi layer reservoirs located at depth 200 to 1500 m TVDSS. This zone is penetrated by different kinds of completion well techniques: gravel pack well for shallow zone and tubingless and dual string well for main and deep zone. The oil...

... technology for well placement. The well was designed with no smart completion due to surface power limitation. First time in the region a dual defensive sand control mechanism was selected, Gravel Pack & Sand Screens. The 1 st ever horizontal well was drilled S field meeting its objective at Q4-2017...

... breakthrough due to inadequate cement quality to isolate water bearing sands below the lower high pressure reservoir Risk 4 – Potential prolonged drilling, hence rig down during the monsoon season Risk 5 – Potential sand production from shallow reservoirs due to unsuccessful gravel pack The steps...

... control for contrasting water encroachments. Due to the unconsolidated nature of the target reservoir, this well is designed for Open-Hole Gravel Pack (OHGP) with specialty 3D filtration screen to manage sanding issue. This paper highlights 2-in-1 application of ICD with enabled zonal shut-off sleeves...

... grain sizes/permeability, premium screens with an enhanced gravel pack technique were used to complete the wells. This paper discusses the development and successful application of this integrated method. A significant challenge in these fields is ensuring hydrocarbon flow through the complex, highly...

... Abstract Multizone Single Trip Gravel Pack (MZ-STGP) Completion has been utilized as primary sand control system in Total E&P Indonesie. Over 250 wells have been successfully delivered since 2005 to maintain production plateau. Currently, the main challenge of this system is how to tackle...

... for Vietnam's domestic gas supply. The infill vertical wells will be completed open hole with external gravel pack and screen as the solids control measures. Reservoir Characterization Artificial Intelligence Drillstem Testing drillstem/well testing offshore Vietnam complex reservoir solid...

... Abstract An aqueous-based linear gel composition comprising diutan gum and an environmentally acceptable stabilizer has been developed for gravel packing applications. This aqueous-based gel works at elevated temperatures greater than 300°F. The rheological properties of these linear gels...

... and the tubing, thus reducing the injectivity. A series of pulsed-neutron logs were recorded in five (5) problematic wells. The objective was to determine if fines migration was the cause of the blockage, using silicon activation and neutron-gamma ray spectroscopy. Silicon activation, also known as Gravel Pack...

.... Because of the many challenges faced in combining the multizone gravel-pack system and the intelligent completion components, both had to be re-engineered to allow for a perfect interface. This resulted in the first intelligent completion installation inside a shunt-tube gravel pack with multizone packers...

... before and after well intervention. In order to provide a cost effective solution for the new potential layer below the existing gravel pack zone, through tubing gravel pack technique was chosen as the sand control technique. This enabled the new zone to be produced in the optimum draw down without...

... A Figure 10 Sieve analysis of five wells in field M Figure 8 water production in a well completed with gravel packs Figure 7 water production in a well completed with gravel packs Abstract In some Persian oil fields hydrocarbon recovery is mainly from sandstone reservoirs...

... Abstract Cased-hole gravel packing is commonly utilized to control sand production from oil and gas wells. The success of a cased-hole gravel-pack job depends on the ability to effectively pack perforation tunnels, which act as conduits between the reservoir and the wellbore for hydrocarbon...

... were deemed unlikely to succeed in this environment and as such these complicated uphill wellbore trajectories required the development of a novel, reverse-port gravel-pack system. This paper will discuss the gravel-pack system and how it addressed the difficult scenarios, including: How...
