Subsurface Exploration Information Needs and SPARQL Queries
This page contains all information needs and SPARQL queries for the Semantic web resource for the Slegge database. Each information need is translated to zero or more SPARQL queries. Some information needs does not have a SPARQL query translation since they require data that is not covered by the Slegge database, and some information needs are translated into multiple SPARQL queries in order to capture variations in the ontology vocabulary and SPARQL expressivity.

1 Information Need 001
In my area of interest (AOI) return the wellbores that penetrates chronostrat unit <C1> and return information about the lithostratigraphy and the hydrocarbon content (saterated and moveable + shows) in the wellbore interval that penetrates the <C1> unit. Also return information about other wellbore intervals with hydrocarbon content (saterated and moveable + shows) in the wellbores with hydrocarbon in <C1>. ## DOMAIN: well, stratigraphy ## COMMENT: ## The hydrocarbon content is not well modelled or mapped yet. ##The "Area of Interest (AOI)" is rather ## abstract and must be conretized in any sparql query. It is ## interpreted in the SPARQL here as either Field, or some arbitrary ## rectangular geographic area ## Queries 07 and 08 only differ in that AOI is field in one, and a geographical area in the other.

3 Information Need 003
Wellbore reservoir info: (previous question in a different manner) In my AOI, return wellbores with reservoir • If there is reservoir, then give assosicated information (overlapping 3d line intervals with attributes + ?3d points with attributes) – Chronostratigraphy (wellbore interval with name, hierarchy, top and base age, top and base depth (MD RKB, TVD MSL,..) – Lithostratigraphy (wellbore interval with name, hierarchy, top and base depth (MD RKB, TVD MSL,..) – Hydrocarbon content (saturated and moveable, residual, shows) – Reservoir properties: Porosity, permeability, Net to Gross ratio, Net thickness (MD), Net thickness (TVD) • Return also any information about insuffisient data coverage to an- swer the question • Possible answer for a wellbore: Wellbore W3 has got a OIL discovery in C1 in the L1. The well bore also got a discovery (gas with oil leg, down to situation) in C2/L3 ..+ TVDs, MDs, porosities, . ## DOMAIN: well, stratigraphy, reservoir ## COMMENT: A "reservoir" is (at least in this context) a wellbore ## interval with measured fluid or gas presence. Specifically, a ## reservoir is here (surprisingly) not a 3d volume, but rather the ## porition of the 3d volume intersected by the ## wellbore. "Insufficient data coverage" is probably out of ## scope. Gross depth is depth measured along wellbore, while net ## depth is the difference in vertical depth between bottom and ## top. (Recall that wellbores are usually not vertical). Net-to-gross ## ratio is the ratio of these depths. It is not clear what "measured ## net thickness" means. Probably this is an error in the ## question. "MD RKB" means : measured depth along wellbore from the ## "rotary kelly bush". The latter is just a standard reference point ## for a wellbore, and its nature is not important for geologists. ## 05.q asks for all the depths of any stratigraphic zones overlapping with the reservoir. ## 06.q asks for all the measurements done along the reservoir plus that 05.q asks for. To be complete, both these blocks are put in optional

Input: A list of wellbores
Output: List all reservoirs (wellbore intervals with measured fluid presence) in the wellbores. For each reservoir list: porosity measurement, permeability measurement, net-to-gross ratio, net and gross thickness, top and bottom in measured depth and true vertical depth of the reservoir and finally all stratigraphic units of stratigraphic zones overlapping/intersecting the reservoir.

Limit to all wellbores with core in Brentgruppen and show key atributes in a table. After connecting to EPDS (slegge) we could for instance limit futher to cores in Brent with measured permeability and where it is larger than a given value, for instance 1 mD. We could also find out whether there are cores in Brent which are not stored in EPDS (based on NPD info) and where there could be permeability values. Some of the missing data we possibly own, other not. ## DOMAIN: well, core, stratigraphy ## THe last question, about cores in EPDS vs. NPD is not properly ## modelled and mapped yet.

I need Well, Wellbore, Wellbore Path, Wellbore Cored Interval, Well- bore Stratigraphy, Core Samples, Sample Analysis, Analysis Permeability, Analysis Porosity to be integrated in such a way that: It is possible to have a result set containing all important attributes in- cluding location. The result set can be filtered by stratigraphy, wellbore name and the other attributes. It should be possible to cross plot permeability vs. porosity vs. depth (MD RKB, TVD MSL, TVD below sea bottom). TVD values can be extracted by using the MD RKB values along 3D wellbore pathes. It should be possible to identify which cores exist in / are missing in either EPDS or NPD or Petrobank. It should be possible to identify which data we have access to that is not loaded into EPDS ## DOMAIN: well, stratigraphy, permeability, depth, core

Input: List of well/wellbore names and stratigraphic units, whether to include child units? Minimum or maximum permeability, minimum or maximum porosity
Output: Output wellbore intervals with the given stratigraphic units, including child units are interpreted. Give all cores taken in overlapping intervals, give permeability, porosity measurements taken in the intervals, output measured depth from rkb and true vertical depth from sea level and sea bottom of the intervals. For the cores also list if they are stored in npd, epds, or both.

I recently got a task to show what wells have cores in a specific set of stratigraphic units. I wanted to do a more generic approach for reuse, and aimed at identifying all wells with cores and what units these cores intersect. Then any user could later filter for the unit(s) of interest. I do several steps to encounter this. Also I include some additional information such as link to wellbore images and link to the EPDS document finder. Next step could be to include more info from internal database(s) and data from the UK side in addition to additional calculations. ## DOMAIN: well, core, stratigraphy

68 Information Need 068
Average effective porosity values of Etive Fm.
##DOMAIN: Porosity, stratigraphy
##COMMENT: All wells with effective porosity logs in the Etive Fm. (between two well markers)
Average porosity if any data source already has it OR, we calculate this in Petrel using porosity logs in loaded into Petrel and the well top markers.
69 Information Need 069
Wells with logs covering > than 1000m vertically ## DOMAIN: log
70 Information Need 070
All wells with time-depth relationships ##DOMAIN: seismic, wellbore ##COMMENT: "Time" means the time for a seismic wave to return.
71 Information Need 071
All wells with TIME_CKS time-depth relationships ##DOMAIN: seismic, wellbore ##COMMENT: "Time" means the time for a seismic wave to return. We do not yet know what TIME_CKS is
72 Information Need 072
Wells with sonic, density logs and time-depth relationships ##DOMAIN: wellbore, log, seismic
73 Information Need 073
Wells with sonic compressional, sonic shear, density, time-depth relationships and LFP log sets ##DOMAIN: wellbore, log, seismic
