SECTIONS IN SEGOFS

INTRODUCTION SEGOFS ENERGY SERVICES LIMITED (SESL) is a 100%

Nigerian company, was incorporated in January 2006 with a primary focus on the provision of top class drilling support services to the oil and gas industry, with arms specialized in provision of directional drilling, 3D laser scanning, pressurized habitat, consultancy and training services.

SESL is guided by the motto:- Do It Right The First Time.

SESL Clients includes:NAOC, CHEVRON, TOTAL, EXXONMOBIL, CONOIL and so

on.

VISION OF THE ORGANIZATION

To maximise the use of local expertise, supported by cutting edge technologies to deliver services to our clients under a competitive price regime without compromising quality, safety and environmental issues.

SESL BUSINESS

HSE POLICYIntroduction Safety is the condition of being protected from or

unlikely to cause danger, risk or damage. Unsafe acts includes, Failure to wear PPE. Wearing unsafe clothing. Horseplay. Unsafe Conditions includes, Hazardous environment. Hazardous equipment.

Continuation… Near misses includes, A personnel was descending a stair case and his

shoe slipped of due to wetness of the floor. He would have fallen down and sustain serious injury (broken legs, hands, broken ribs and teeth) but was able to hold the two rail and regained balance.

Accidents are unplanned incidents causing injury and death. Examples are

Situation where a stab suspended from a crane falls and squashes an unsuspecting worker below it.

SAFETY GOALS The SESL goals establishes for safety includes: Provide safe and healthful working conditions. Prevent accidents and accidents-related causes. Eliminate occupational illnesses. Protect the environment. And so on.

General Safety Guidelines Employees shall ensure that proper clothing and PPEs

are worn all times. Apply safe lifting procedure while engaging in the act

of lifting. Employees should be familiar with company and client

emergency notification system.

SAFETY INCENTIVES Almost all accidents are preventable. They are caused

by Human error Omission Failure to observe Ignorance Inexperience. And so on.

Awards and gifts are given as incentives for employees that meet company safety goals.

SAFETY VIOLATION AND DISCIPLINARY ACTION

Progressive disciplinary action on safety violation are: Verbal Warning. Written Warning. Final Written Warning. Termination.

HSE POLICY STATEMENT A policy is a course or principle of action adopted or proposed

by an organization or individual. SESL HSE Policy is enacted to ensure maximum security, safety of personnel and protection of the environment.

SESL safety policy statements are summarized thus Health policy Safety policy Environmental policy Emergency Response Policy Security Policy Transport Policy Community Relations Policy Cashes Policy Drug And Alcohol Policy

PERMIT TO WORK This is a permit that must be obtained before one is

allowed to work in any oil and gas facility. Permit to work includes: General Work Permit Hot Work Permit Confined Space Entry Permit. Excavations Permit Lockout Tagout

Introduction to Directional Drilling

Directional Drilling is the science of deviating a wellbore along a predefined course to a defined subsurface target.

Applications of Directional: Sidetracking Inaccessible Location Multiple Exploration Wells from a Single Wellbore Onshore to Offshore Drilling Horizontal Wells

WELL PLANNING Well planning is defined as those engineering activities,

which follows follow on from the identification of a subsurface target for a well (exploration, appraisal, or development well) until the completion of that well. This activities includes:

Definition of well objectives Planning of well trajectory Selection of drilling hardware (bits, tubulars, mud etc) Planning of casing points Selection of logging tools(MWD, LWD) Testing program and decision criteria for testing Completion program and criteria for completion

SURVEY Survey are carried out to ascertain the latest bottom-

hole position. At the end of a successful survey, the following three

pieces of information are known: Survey Measured Depth Borehole Inclination Borehole Azimuth

SURVEY CALCULATIONS METHOD

Survey calculation methods include: Tangential Method Average Angle Method Radius of Curvature Method (Most Accurate) Minimum Curvature Method (Most Accurate) Survey in SESL is calculated using Minimum Curvature

Method

FEATURES OF A DIRECTIONAL WELL PROFILE

A directional well profile is the planned well trajectory from the surface to the final drilling depth by projecting the wellbore onto two plotted planes.

In order to determine the best geometric well profile from the surface to the bottomhole target, the following information must be known

Position of surface location

Position of target location

The true vertical depth

Features of a directional well profile are as follows: Surface Location Kickoff Point Well Inclination End of Build Hold Angle Tangent Section Start of Drop End of Drop Target Displacement Target Location Drop off Rate Build up Rate

Continuation… Turn Rate Measured depth Horizontal displacement Azimuth
