(a)provides a spatial representation of the distribution of the following in the relevant complex—

(i)sediment;

(ii)rock;

(iii)wells (if any), and

(b)simulates the flow of fluids in the relevant complex.

(2) In this Schedule the following terms have the meanings given by Article 3 of the CS Storage Directive (and cognate expressions are to be construed accordingly)—

“corrective measure”;

“hydraulic unit”;

“leakage”;

“migration”;

“significant irregularity”;

“storage complex”;

Survey information

2.—(1) The survey information is any carbon storage information which—

(a)is survey data,

(b)if a device is used to generate the energy used in a survey, relates to the position of the device when measurements are taken during the survey,

(c)relates to the position of the sensors used to detect the energy used in a survey when measurements are taken during the survey,

(d)is data derived from the processing of survey data, where—

(i)the processing takes place during the survey, or

(ii)the data is used to create to the final product,

(e)is the final product,

(f)is a report relating to the acquisition or creation of survey data,

(g)is a report relating to the processing or reprocessing of survey data, or

(h)is a report relating to the final product.

(2) In this paragraph—

“the final product”, in relation to a survey, means the final 2D, 3D or 4D image of the subsurface which results from the processing of survey data—

“survey data” means data acquired or created in the course of a survey.

Well information

3.  The well information is any carbon storage information which—

(a)relates to the position or dimensions of a well, including the directional path of any borehole,

(b)relates to the materials, equipment and components used in any of the following activities in relation to a well (each a “relevant activity”)—

(i)drilling;

(ii)any test carried out on any fluids or other substances encountered;

(iii)any test carried out on the well;

(iv)any work for the purpose of bringing a well into operation and which is carried out after the well has been drilled (including, for example, the installation of a casing);

(v)operation;

(vi)maintenance;

(vii)suspending the operation of the well so that it may be re-used for, or in connection with, the storage of CO₂ or other works;

(viii)plugging;

(ix)abandoning the well permanently;

(x)monitoring;

(c)summarises a relevant activity, or

(d)relates to the strata, formations or fluids which are, or may be, encountered while undertaking a relevant activity.

Site information

4.—(1) The site information is any carbon storage information (other than the survey information or a CO₂ storage model) which relates to a matter specified in sub-paragraph (2).

(2) The matters mentioned in sub-paragraph (1) are—

(a)the subsurface;

(b)the geology of the strata;

(c)the geological formation of—

(i)a hydraulic unit,

(ii)a storage site, or

(iii)a storage complex;

(d)the chemical composition of a fluid occurring naturally in—

(i)a hydraulic unit,

(ii)a storage site, or

(iii)a storage complex;

(e)how CO₂ behaves, or may behave, in—

(i)a hydraulic unit,

(ii)a storage site, or

(iii)a storage complex;

(f)how CO₂ may migrate;

(g)the assessment of the integrity of any well in a storage site or a storage complex.

Injection and production information

5.—(1) The injection and production information is any carbon storage information which—

(a)is an estimate of—

(i)the total quantity of CO₂ that could be stored in a storage site or a potential storage site;

(ii)the proposed injection rates of CO₂,

(b)relates to the quantity of a fluid which is injected—

(i)in the period of 24-hours beginning when it is first injected, and

(ii)in each following period of 24-hours,

(c)relates to the injection rates for a fluid,

(d)relates to the quantity of a fluid or other substance which is produced from a storage complex—

(i)in the period of 24-hours beginning when the particular fluid or other substance is first produced, and

(ii)in each following period of 24-hours,

(e)relates to the chemical composition or characteristics of a fluid or other substance falling within paragraph (b) or (d),

(f)relates to the quantity of a gas which is—

(i)produced from a storage site, and

(ii)flared or vented, or used, in or during the operation of the site,

(g)relates to the chemical composition or characteristics of a gas falling within paragraph (f),

(h)relates to the pressure or temperature in a storage complex during—

(i)injection of a fluid, or

(ii)production of a fluid, or

(i)is, or relates to, the most recent version of a CO₂ storage model.

(2) In this paragraph “characteristics” includes temperature and pressure.

Monitoring information

6.  The monitoring information is any carbon storage information which relates to the monitoring of a storage complex or injection facilities for the purposes of—

(a)comparing the actual and modelled behaviour of a substance in a storage site;

(b)detecting any significant irregularities;

(c)detecting migration of CO₂;

(d)detecting leakage of CO₂;

(e)detecting any significant adverse effects on the surrounding environment;

(f)assessing the effectiveness of any corrective measures taken;

(g)assessing the safety and integrity, both short-term and long-term, of the storage complex (including in particular, the assessment of whether the stored CO₂ can or will be completely and permanently contained).

Installation information

7.—(1) The installation information is any carbon storage information which relates to—

(a)the position or dimensions of a relevant installation,

(b)the materials, equipment and components used in any of the following—
