Introduction
This International Standard is based on API Spec 6A, seventeenth edition, February 1996, its errata and supplement, and API Spec 6AV1, first edition, February 1996. The contents of API Spec 14D (upon which ISO 10433 was based) and API Recommended Practice 14H (upon which ISO 10419 was based) have been incorporated in API Spec 6A, seventeenth edition.
The International System of units (SI) is used in this International Standard. However, nominal sizes are shown as fractions in the inch system. The fractions and their decimal equivalents are equal and interchangeable. Metric conversions and inch dimensions in this International Standard are based on the original fractional inch designs. Functional dimensions have been converted into the metric system to ensure interchangeability of products manufactured in metric or inch systems (see also Annex B).
Tables referenced in the main body of this International Standard which are marked with an asterisk are repeated in Annex B in US Customary units with the same table number as in the main body but with the prefix B. In figures where dimensions are only given in inches, the values of surface roughness have been indicated in accordance with US draughting conventions. See also Annex M for listings of tables and figures.
Users of this International Standard should be aware that further or differing requirements may be needed for individual applications. This International Standard is not intended to inhibit a vendor from offering, or the purchaser from accepting, alternative equipment or engineering solutions for the individual application. This may be particularly applicable where there is innovative or developing technology. Where an alternative is offered, the  vendor should identify any variations from this International Standard and provide details.

A well is classified as a "wildcat" (exploratory) well if Its purpose is to discover a new petroleum reservoir. In contrast, the purpose of a development well is to exploit a known reservoir. Usually the geological group recommends wildcat well locations, while the reservoir engineering group recommends development well locations. The drilling engineering group make. the designs and cost estima tes for the proposed wells. The legal group secure the necessary drilling and production rights and estab lishes clear title and rightof- way for access. Surveyors establish and stak e the well location .
Usually the drilli ng is do ne by a drilling contractor . Once the decision to drilllhc:well is made by management. the drilling engi neering group prepares a more detailed well design and writes the bid specifications. The equipment and procedures that the operator will require, together with a well desc ription, must be included in the bid specifications and drilling contract. In areas where previo us experience has shown drilling to be routine, the bid basis may be the cost per foot of hole drilled. In areas where costs can not be estimated with responsi ble certai nty, the bid basis is based on cos t per price per day. In some cases, the bid is based on cost per foot down to a certain depth or formation and cost per day beyond that point. When the wen is being financed by more than one company, the well plan and drilling contract must approved by dri lling engineers representing the various companies involved.
Aller drilling begins, the manpower required to drill the well and solve any drilling problems that occ ur are provided by:

• The drilling contractor.
• The well operator.
• Various dr illing service companies.
• Special consultants.

Final authori ty tests either with the drilling contractor when the rig is drill ing on a costper- foot basis or with the well operation when the rig is drilling on a cost-per-day basis. Shows a typical drilling organization often used by the drilling contrac tor and well operator when a well is drilled on a cost-per-day basis.

Quality runs deep
The driving force behind the advanced designs and successful installation of our products has always been our customers’ demand for more effi cient and reliable drilling. VetcoGray’s patented metal-to-metal seal, advanced material sciences and overall innovative approach combine to help our clients reliably drill deeper wells at the sea floor. 
We provide the broadest range of subsea wellhead solutions for global exploration and production. Our portfolio features the familiar MS-700, the SlimBore system for drill thru/slim riser applications and the MS-800 FullBore for ultra deep wells. All our solutions feature the fi eld-proven MS sealing technology and running tool designs.

Features and benefits
Metal-to-metal sealing
Fundamental to the MS-700 subsea wellhead system is the MS seal which has been proven to be the most reliable metal-to-metal seal offered in the industry.
Dual tapered sockets
The tapered socket design between the high-pressure and low-pressure housing reduces fatigue in the casing by transmitting the load directly into the conductor housing. No preloading is required to get maximum bending capacity.
Below-mudline equipment
16” submudline equipment allows an additional casing string to be hung at a predetermined position under the wellhead. The system is installed with a single trip running tool that installs both the casing hanger and the seal.
Running tools
Since the inception of the MS-700, VetcoGray has provided a host of running tools that reduce operating times and risk associated with drilling a subsea well.

Flopetrol Johnston–Schlumberger downhole tools history The history of the drillstem test (DST) goes back to 1926, when E. C. and M. O. Johnston developed the first commercial downhole testing tools. The two brothers were working in the oil fields in Arkansas, USA, where local conditions required frequent and expensive formation testing in a cased hole. The first tool developed incorporated a tester valve and a conical packer element (Fig. 3). It was used in openhole, saving the cost of running casing to test. The field tests were successful, and the brothers continued to work on improving the tools.
Many new tools and techniques were introduced by Johnston Testers. The 1930s saw the introduction of water cushions to reduce differential pressure, a straight hole packer that did not require a core hole and pressure recorders to distinguish between a bad well and tool problems.
During the 1940s reverse circulating subs were invented to get recovered oil out of the pipe before tripping out of the hole. In addition to numerous tool improvements in the 1950s, tubing conveyed-perforating was introduced.

Further developments resulted in the MFE* Multiflow Evaluator system in 1961, the first PCT* Pressure Controlled Tester valve system in 1971, the fullbore PCT system in 1980 and the intelligent IRIS tools in 1992. In 1994 a consortium of 11 clients qualified a full range of tools for hostile HPHT conditions with maximum annulus pressures up to 25,000 psi and temperatures above 400°F [204°C]. Later, a selection of tools with an innovative sealing system was qualified for temperatures up to 500°F [260°C]. The process continues (Fig. 4); the Schlumberger design team liaises with field personnel and clients to develop new downhole tools to further enhance
tthe capabilities of test strings—and thus maintains the tradition started in 1926.
