THE OFFSITE PROJECTS TEAM HAVE COMMISSIONED VARIOUS STRATEGIC PROJECTS IN 2022 IN LINE WITH THE GDN FIVE (5) YEAR PLAN AIMED AT DEVELOPING AN ADVANCED, RELIABLE, AND SAFE GAS DISTRIBUTION NETWORK TO MEET THE KINGDOM’S GROWING GAS DEMAND.
 Hafeera and Shabach Redundancy Pipelines: This project aims to install new pipelines at the south part of the GTN to enhance the redundancy and reliability to supply the Khuff gas to Al Dur Power and Water plant Phase I and II through DDP station. Pipelines were installed and commissioned as per project scope.
 PU Hookup Plan for Eight (8) Wells: Following the discovery of new gas reserves in the Jauf and Jubah reservoirs, Tatweer Petroleum has undertaken a Drilling Program to drill eight new Pre-Unayzah wells in the Bahrain Field for appraisal purposes. The project is in progress and during 2022 one (1) well has been completed and put onto production. The remaining wells are expected to be commissioned starting from Q2 2023 with the target to complete all wells hook up by Q1 2024 based on the current drilling plan.
 Khuff wells Ultimate Tie In Destination (UD): Considering the depleting reserves and pressure in the Khuff gas reservoir and in order to ensure that gas demand over the upcoming years is met, a set of existing and new Khuff wells have been identified to be connected to Low Pressure (LP) facilities (GDUs and NCFs). Ten x well hook-ups are under execution and 19 x well hook-ups are under Tendering.
 CGDF Compression Facilities (Central NCF): In order to support the depleting Khuff reservoir pressure, a feasibility study to install CGDF Compression Facilities was completed during 2022. Based on modelling and forecast input and as a feasibility study outcome, central NAG compression facilities (CNCF) will be installed upstream of the existing CGDF to enhance the NAG system deliverability in order to meet the Kingdom’s Khuff gas demand. The Central NCF Station capacity is currently under evaluation.
 LP Modifications of K42 and K43: In order to meet gas demand during the Low Pressure (LP) operating phase and to prolong the life of connected wells, a comprehensive debottlenecking study to enhance the capacity of existing seven (7) remote GDUs# K37 to K43 during the LP operating phase was conducted by Schlumberger (CAMERON). The study report defines modifications to be carried out to increase expected LP capacity from 25 to 43 MMSCFD. Implementation will be in stages.
Gas Distribution Network (GDN) Projects
The Offsite Projects team have commissioned various strategic projects in 2022 in line with the GDN Five (5) Year Plan aimed at developing an advanced, reliable, and safe gas distribution network to meet the Kingdom’s growing gas demand.
Highlighted below is a high-level summary of the key, strategic GDN project updates for 2022:
 GDN Debottlenecking and improving redundancy project: The Project introduces two new gas pipelines from Hidd Metering Station (HMS) to Alba Gas Station (AGS) jump-over and caters to the forecasted pressure drop of the Khuff gas reservoir, eliminates existing bottlenecks in the pipeline network, introduces redundancy to the system and enables the safe transportation of re- gasified liquefied natural gas (LNG) from Bahrain LNG to the Bahrain Field. All stages of the project are under construction currently.
