ADVANCED WELL CONTROL FOR COMPLETIONS & WELL INTERVENTION PROFESSIONALS 31 August – 4 September 2015 | Bandung | Indonesia

About this course In the aftermath of the Macondo blowout most operating companies across the

globe are reviewing how they manage well control. In most cases the focus of

attention has been directed towards drilling operations. However, many well

control incidents occur during completion, workover and intervention operations.

This five day course covers all of the important aspects of well control during dead

(killed) well completion and workover operations. Also covered are live well

intervention operations (wireline, coiled tubing and hydraulic workover).

With the inclusion of subsea intervention riser systems, riserless subsea

interventions, pumping and stimulation operations and well testing operations

the syllabus goes beyond that currently covered by the IWCF well intervention

pressure control course.

Course Objectives

This course is designed to improve your understanding of well intervention and

completion well control. By the end of the course:

You will be able to identify the necessary well control requirements for

completion, workover and intervention operations on both live and killed

wells.

You will understand the consequences of a loss of well control and therefore

the importance of ensuring that the correct control are in place, and

maintained throughout the operation.

You will have the necessary skills to enable you to properly identify the risks

associated with working on live wells and to further ensure that the necessary

mitigation is in place to reduce risk to an acceptable level.

You will understand the importance of crew competence with respect to well

control and well integrity during completion and intervention operations.

Should a well control incident arise, you will have the necessary skill to

minimise the loss of containment and make restore control.

Who Should Attend

This is an important course for anyone who is responsible for planning

completion, workover or intervention operations. It is especially relevant those

with a supervisory role at the well site.

Pre-Requisite

Although prior attendance at an IWCF or IADC well control course is not essential,

students who have a basic knowledge of completion and intervention well control

techniques will find the course easier to follow. Students should be able to carry

out basic hydrostatic and volume calculations before attending the course (these

will be covered, but only briefly - more of a refresher than formal instruction.)

Students must bring a calculator. Note: The majority of the course will be taught in Oilfield units (feet, inches, psi, PPG, bbls etc).

About your Expert Trainer Howard Crumpton Howard has over 30 years in the oil industry. During that time he has worked exclusively in well intervention and completions.

After a number of years working for intervention service companies (mostly slickline) he joined BP as an offshore well service supervisor. He was responsible for the day to day supervision of well intervention work on many of BP’s North Sea platforms. This included coil tubing, e-line, slickline and stimulation operations. An office based role as a well operations engineer followed. He was responsible for planning, programming and organising of all the well intervention work on the Bruce and later the Magnus fields. In 1995 Howard moved into completion design. Since then he has designed many platform and sub-sea completion’s, often travelling to the rig site to oversee the installation. In addition to his day to day work as a completion engineer, Howard regularly teaches completion and well intervention courses all over the world. Current and more recent assignments include the following: Currently developing training material for the

BP/Chevron drilling training alliance in preparation for a new course – Completion Practices.

Carried out tubing stress analysis study for Tullow Oil. Field wide analysis for the Jubilee Field. A deepwater development offshore Ghana.

Carried out the design programming and supervised the execution of a new sub-sea gas lifted production well in the BP Dyce – Machar East field. Programmed the first use of Surgifrac coil tubing acid fracturing in the North Sea.

BP planned a number of extended reach wells from the Magnus platform. Brought in to assist with designing the completions, in particular to prepare a basis of design for intervention requirements in wells with long high angle trajectories.

Worked on the design, programming and offshore supervision of three ‘intelligent’ wells for Cairn Energy’s Sangu field in Bangladesh.

Completions engineer for Miller Platform, McLure and Rhum sub-sea development - BP Aberdeen. Responsible for all aspects of Miller completions, including determination of tubing size, metallurgy, detailed stress analysis, program preparation, implementation, direct offshore supervision and finally reporting and appraisal.

ADVANCED WELL CONTROL FOR COMPLETIONS & WELL INTERVENTION PROFESSIONALS 31 August – 4 September 2015 | Bandung | Indonesia

DAY 1 MORNING CASE HISTORIES

A series of well control incidents will be examined. Class discussion will focus on what went wrong. The class will also be encouraged to identify mitigation measures that should have been in place to prevent the incident. Amongst the incidents examined will be Macondo.

RECOGNISING POTENTIAL

In this session the class will examine a non oilfield safety related incident, for example the NASA space shuttle Challenger disaster. Can

the oil industry learn from the incidents like this in our approach to accident prevention.

COMMAND AND CONTROL

Using examples the class will discuss the importance of having clearly

defined roles and responsibilities for well-site personnel. AFTERNOON WELL CONTROL FUNDAMENTALS

A revision session - to ensure all participants are able to perform the basic hydrostatic and volume calculations that are an essential part of any well kill planning.

WELL CONTROL AND WELL INTEGRITY BARRIERS Based on the NORSOK D010 document the concept of well control barriers will be introduced to the class. Using well schematics, participants will be asked to identify primary and secondary barrier envelopes. The class discussion will also cover barrier failure and

remedial actions to restore barrier integrity in the event of a failure.

DAY 2 MORNING COMPLETION AND INTERVENTION FLUIDS

This session will cover the fundamentals of using workover and completion fluids (principally brines). It will concentrate on brine weight adjustments associated with density loss because of temperature increase. A brief summary of the main formation damage

mechanisms associated with poorly designed fluid systems will be included.

WELL CONTROL DURING LIVE WELL INTERVENTIONS - WIRELINE

Wireline pressure control equipment will be described (slickline, e-line and braided cable). Barrier philosophy for performing wireline interventions on live wells will be discussed at length. The session will also include best practices to prevent loss of pressure integrity and mitigation should pressure integrity be lost. A class exercise (working in

teams) will be used to reinforce the lecture. AFTERNOON RECOGNISING KICKS AND SHUTTING IN THE WELL

Shutting in a well during completion and workover operations is often complicated by having 'non standard' pipe across the BOP. For example how should the well be shut in if there is weak, holed and corroded pipe, sand control screens, or ESP cables across the stack when a kick occurs.

KILLING A LIVE WELL – BULLHEAD

This session introduces the first of the three main well kill methods that will be taught. After being taken through a worked example, the participants will be given a series of well kill problems to solve. Time

permitting, tapered string and deviated well examples will be introduced. This session will also begin to address some of the problems associated

with killing multi-lateral wells, multi-zone wells high angle or horizontal wells and wells with depleted reservoirs.

DAY 3 MORNING WELL CONTROL DURING LIVE WELL INTERVENTIONS - COILED TUBING

Coiled pressure control equipment will be described. Barrier philosophy for performing coiled tubing interventions on live wells will be discussed at length. The session will also include best practices to prevent loss of pressure integrity and mitigation should pressure integrity be lost. A

class exercise (working in teams) will be used to reinforce the lecture.

WELL CONTROL DURING WELL TEST OPERATIONS This session will concentrate on the barriers that are in place during a

well test using a DST string and temporary (well testing) production facilities. The correct response to the failure of a downhole barriers and a leak at surface will be discussed.

AFTERNOON

KILLING A LIVE WELL - REVERSE CIRCULATION

This session introduces the second of the three main well kill methods that will be taught. After being taken through a worked example, the participants will be given a series of well kill problems to solve. Time permitting, tapered string and deviated well examples will be

introduced. DAY 4 MORNING

WELL CONTROL DURING LIVE WELL INTERVENTIONS - HYDRAULIC

WORKOVER The basic hydraulic workover unit pressure control equipment will be

described. Barrier philosophy for performing snubbing operations on live wells will be discussed at length. The session will also include best practices to prevent loss of pressure integrity and mitigation should pressure integrity be lost.

WELL CONTROL DURING PUMPING AND STIMULATION OPERATIONS.

AFTERNOON

PROCEDURES FOR DEALING WITH GAS MIGRATION

WELL KILL - LUBRICATE AND BLEED

This session introduces the last of the three main well kill methods that will be taught. Both the constant volume and constant pressure method will be taught. After being taken through a worked example, the participants will be given a series of well kill problems to solve.

DAY 5 WELL CONTROL DURING SUBSEA (FLOATING UNIT) COMPLETIONS,

WORKOVERS AND INTERVENTIONS

This session will describe the tree basic intervention riser systems used with horizontal (spool) trees, conventional 5 x 2 dual bore vertical trees and mono-bore vertical trees. An overview of the disconnect procedure for each riser type will be included.

The subsea session will also discuss the effects of water depth of formation fracture pressure riser margins and choke line friction. The class will be given a subsea well kill problem to solve.

RISERLESS SUBSEA INTERVENTIONS A brief overview of interventions using mono-hull vessels and the sub-sea wireline lubricator.

WORKOVER PROBLEM A final class exercise (time permitting) will be based on a workover problem. The participants will be given a data pack detailing the workover requirements for a failed well. Working in teams they will be

asked to prepare a well kill plan, determine barrier requirements (for removal of the production tree and installation of the rig BOP) and identify the principle well control risks associated with the operation.
