Abstract The Total Exploration and Production Nigeria Limited has been operating its first discovered field in Nigeria for more than 40 years as an oil dominated field but the future potential of the field is gas. Hence, the decision to upgrade the field to harness the gas potential as well as achieving the national priorities of flare down and gas supply to the domestic market. After several studies and evaluation of various options, it was decided to carry out the upgrade in Simultaneous Operations (SIMOPS) mode. The upgrade involved triple SIMOPS of oil and gas production, drilling in a gas well cluster and heavy construction (Upgrade Projects). This SIMOPS is uncharacteristically complex with the following elements; more than 3 years non-stop activities, more than 6 million man-hours, more than 4,000 people working together out of which more than 80% are semiskilled and unskilled local community personnel; involvement of consortium of 3 contractors who have never worked together in the past, more than 15 major subcontractors, unknown underground conditions of the installations, aging facility with assets integrity challenges, over 2000 lifting of loads above high pressure live-lines, large number of thermal engines (mobile and stationary) and other ignition sources in hazardous zones and so on. The Company (Project management team and Production team) together with the contractors jointly put together some well thought out Safety initiatives to contain the identified risks. Some of these initiative include; effective risk assessment mechanism, strict control of ignition sources and looping the ignition engine Emergency Shut-Down (ESD) to the plant ESD, drop object study and crash test of protective barrier built across high pressure live-lines, sectionalization of SIMOPS zones, joint project and production emergency drills, technical and HSE competence development to mention but a few. More than 24 million contractors’ man-hours achieved and about 6 million man-hours remaining with a lot of challenges that the project has encountered. This paper will present in detail what the company implemented to achieve HSE results such as Total Recordable Injury Rate (TRIR) of 0.37 and Lost Time Injury Frequency (LTIF) of 0.10.
Abstract Several ‘mini’ planning existed in the past in some operations’ departments in TEPNG-JV district. These planning were not quite effective as they were neither integrated nor centrally coordinated. There were no structured processes, no structured planning review meetings, no common planning rules and no planning organization. The various disciplines simply worked in silos. Looking at the title, the questions that might be on the lips of the reader is what is integrated operations planning? What does it entail? What role does it play in day-to-day business of oil and gas production? Integrated Operations Planning is a consolidated, ‘live’ planning that gives a single view on all planned operational activities. It is a decision-making tool used by Top management, Managers, Engineers and Technicians at varying degrees. It is used in identifying and resolving operational conflicts, optimizing production, negotiating contracts, deciding on SIMOPs (Simultaneous operations) and Co-activities, rig planning, wells interventions planning, budgeting, forecasting short, medium and long term offshore and onshore accommodation needs as well as in the preparation of the yearly reserves evaluation (PRIME) and Long term planning (LTP) exercises. Integrated Operations Planning (IOP) encompasses all key areas of operations; Drilling, Completion & Well Interventions, Shutdown operations, Engineering (Process, Mechanical, Instrumentation, Electrical, Structural), Construction, Maintenance, Contracts, Procurement, Technical Logistics, Production Technology, Geosciences, Development Planning, HSE, Production, Inspection, Gas business, LNG, Government and Partners Interface. This planning, which started a few years ago in TOTAL E&P Nigeria (TEPNG-JV District), has been quite impactful, as it has resulted in time, monetary and resources savings. This paper seeks to highlight these impacts.

Abstract It is a unique situation amongst the fields operated by Total that has recently taken place on the OML58 Oil and Gas facilities located in the Niger Delta area of Nigeria. Major financial investments over 4 years, and more than 4000 workers at peak on the different locations of the field, for a total of more than 20 millions worked hours, were necessary to complete the first phase of the transformation of an oil producing site into a gas producing site. Eventually, the field will have its life extended for another 30 years, but if it is mainly oil that has been produced so far, 80 % of the future production will be gas. These few figures illustrate what is at stake in a region where Total has been operating for over 45 years and has confidence to go further and bring the installations to their full production capacity. Right from the beginning, it was decided that Simultaneous Production and Construction Operations (SIMOPS) would be the mode of operations. Large scale SIMOPS on remote existing aging facilities, spreading over years, is definitely not a usual challenge. It is even more difficult when it takes place on running installations where gas under high pressure circulates almost everywhere. Therefore, a dedicated organization allowing a strict control of the SIMOPS was implemented. The paper will describe the advantages of a transversal approach where production operations teams and construction teams are aligned on common shared objectives. It will also show how a challenging operating approach in a difficult context (unknown underground conditions, aging facility challenges, etc) can lead to a significant reduction of production short-falls without compromising safety. Furthermore, the case will also highlight how such a big project can positively impact the development of local communities and participate to their sustainable development.

Abstract The use of different fragments of planning's existed across entities in Total E & P - JV District but these planning were neither integrated nor centrally coordinated which resulted in: poor visibility of inter-relationship with other entities, making it time consuming to identify clashes and concurrent activity issues; inability to optimize/align activities with production shortfalls; use of different planning tools/templates which resulted in duplication of data/activities & planners spending much time in data entry and generating reports; and difficulty with linking Integrated Planning (IP) to organizational business model/budget which gives a poor overview of the operational cost/efficiency and resources optimization. These prompted the IP transformation project, where a review of the situation along with its limitation were discussed during workshops organized with entity schedulers and their management. Return on experience from other affiliates on Implementation of IP were also reviewed and data gathered/feedbacks from entities were used to develop the new IP deliverables. A central enterprise planning software was adopted, schedulers were selected, trained and processes, rules were equally defined and developed. We now have a single centrally coordinated IP database that now enables the identification of anticipate clashes and Synergies, proper POB management, enhancement of Contracts and Procurement to better anticipate required resources (materials), follow progress, Improved communication and transverse approach across the Total E & P JV-District, arbitration and report when required and incorporation of IP in established JV business processes. The scope of the transformation project includes HSE, Production, Maintenance, Drilling and Completion/Well Services, General Services, Events, Inspection, Engineering/Construction and Projects, Contracts and Procurement, Shutdown, Campaign of Works, Technical Logistics and General Activities. These entities can now extract planned activities with varied time scales with deliverables ranging from weekly, 4monthly, 1 yearly (work program) and 24 monthly.

Abstract OBAGI is an onshore oil field located on OML58, 85 km north-west of Port-Harcourt, Nigeria. It is composed of 26 stacked reservoir levels with an estimated total OOIP of 1.2 Gbbls. It was discovered in 1964 and has been producing since 1966 through 123 wells and 257 completions. 21 layers have been developed. With a global recovery to-date of 50% and an average producing water-cut of 75%, OBAGI can be considered as a mature oil field. Current activities are driven by two main objectives:to sustain short term production level, and to identify potential remaining resources for additional developments Appropriate monitoring and global static/dynamic review are the key factors to achieve these objectives. The short term objective is to maintain production by optimizing the injection capacity. Difficulties to model reservoir performance have resulted in implementation of an intensive monitoring program. This is to limit water production and to maintain/increase water injection capacity. For the long term, it is believed that potential resources not accessible with current wells could effectively double the remaining reserves. For this purpose, complementary developments have to be proposed to target clearly identified attic oil or by-passed regions. A pragmatic approach was adopted based on 2G model review, material balance study and fluid contact updates (with regular saturation survey campaigns) to identify additional reserves potential. The progress of the study is presented for one of the layers of the field. Introduction OBAGI is an oil field located onshore Nigeria (Figure 1) and discovered in 1964. The OOIP has been estimated to 1.2 Gbbls, split in 26 stacked reservoir levels (Figure 2). Oil production started in 1966 and the maximum of 70,000 bopd was reached in 1983. Both oil and gas productions are currently valorised thanks to Obite Gas Plant start-up in 1999 (also located on OML58). Therefore, although Obagi is mainly an oil field, 5 gas caps are also considered for future production. All produced water is reinjected into the field to minimise environmental impact and support the reservoir pressure.
